Using OpenID Connect (OIDC) to Protect Service Applications using Bearer Token Authorization
You can use the Quarkus OpenID Connect (OIDC) extension to secure your JAX-RS applications using Bearer Token Authorization. The Bearer Tokens are issued by OIDC and OAuth 2.0 compliant authorization servers, such as Keycloak.
Bearer Token Authorization is the process of authorizing HTTP requests based on the existence and validity of a Bearer Token. The Bearer Token provides information about the subject of the call which is used to determine whether or not an HTTP resource can be accessed.
The following diagrams outline the Bearer Token Authorization mechanism in Quarkus:
-
The Quarkus service retrieves verification keys from the OpenID Connect provider. The verification keys are used to verify the bearer access token signatures.
-
The Quarkus user accesses the Single-page application.
-
The Single-page application uses Authorization Code Flow to authenticate the user and retrieve tokens from the OpenID Connect provider.
-
The Single-page application uses the access token to retrieve the service data from the Quarkus service.
-
The Quarkus service verifies the bearer access token signature using the verification keys, checks the token expiry date and other claims, allows the request to proceed if the token is valid, and returns the service response to the Single-page application.
-
The Single-page application returns the same data to the Quarkus user.
-
The Quarkus service retrieves verification keys from the OpenID Connect provider. The verification keys are used to verify the bearer access token signatures.
-
The Client uses
client_credentialsthat requires client ID and secret or password grant, which also requires client ID, secret, user name, and password to retrieve the access token from the OpenID Connect provider. -
The Client uses the access token to retrieve the service data from the Quarkus service.
-
The Quarkus service verifies the bearer access token signature using the verification keys, checks the token expiry date and other claims, allows the request to proceed if the token is valid, and returns the service response to the Client.
If you need to authenticate and authorize the users using OpenID Connect Authorization Code Flow, see Using OpenID Connect to Protect Web Applications. Also, if you use Keycloak and Bearer Tokens, see Using Keycloak to Centralize Authorization.

Quickstart
Prerequisites
To complete this guide, you need:
-
Roughly 15 minutes
-
An IDE
-
JDK 11+ installed with
JAVA_HOMEconfigured appropriately -
Apache Maven 3.8.1+
-
A working container runtime (Docker or Podman)
-
Optionally the Quarkus CLI if you want to use it
-
Optionally Mandrel or GraalVM installed and configured appropriately if you want to build a native executable (or Docker if you use a native container build)
Architecture
In this example, we build a very simple microservice which offers two endpoints:
-
/api/users/me -
/api/admin
These endpoints are protected and can only be accessed if a client is sending a bearer token along with the request, which must be valid (e.g.: signature, expiration and audience) and trusted by the microservice.
The bearer token is issued by a Keycloak Server and represents the subject to which the token was issued for. For being an OAuth 2.0 Authorization Server, the token also references the client acting on behalf of the user.
The /api/users/me endpoint can be accessed by any user with a valid token. As a response, it returns a JSON document with details about the user where these details are obtained from the information carried on the token.
The /api/admin endpoint is protected with RBAC (Role-Based Access Control) where only users granted with the admin role can access. At this endpoint, we use the @RolesAllowed annotation to declaratively enforce the access constraint.
Solution
We recommend that you follow the instructions in the next sections and create the application step by step. However, you can go right to the completed example.
Clone the Git repository: git clone https://github.com/quarkusio/quarkus-quickstarts.git, or download an archive.
The solution is located in the security-openid-connect-quickstart directory.
Creating the Maven Project
First, we need a new project. Create a new project with the following command:
This command generates a Maven project, importing the oidc extension
which is an implementation of OIDC for Quarkus.
If you already have your Quarkus project configured, you can add the oidc extension
to your project by running the following command in your project base directory:
quarkus extension add 'oidc'./mvnw quarkus:add-extension -Dextensions="oidc"./gradlew addExtension --extensions="oidc"This will add the following to your build file:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-oidc</artifactId>
</dependency>implementation("io.quarkus:quarkus-oidc")Writing the application
Let’s start by implementing the /api/users/me endpoint. As you can see from the source code below it is just a regular JAX-RS resource:
package org.acme.security.openid.connect;
import javax.annotation.security.RolesAllowed;
import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import org.jboss.resteasy.reactive.NoCache;
import io.quarkus.security.identity.SecurityIdentity;
@Path("/api/users")
public class UsersResource {
@Inject
SecurityIdentity securityIdentity;
@GET
@Path("/me")
@RolesAllowed("user")
@NoCache
public User me() {
return new User(securityIdentity);
}
public static class User {
private final String userName;
User(SecurityIdentity securityIdentity) {
this.userName = securityIdentity.getPrincipal().getName();
}
public String getUserName() {
return userName;
}
}
}The source code for the /api/admin endpoint is also very simple. The main difference here is that we are using a @RolesAllowed annotation to make sure that only users granted with the admin role can access the endpoint:
package org.acme.security.openid.connect;
import javax.annotation.security.RolesAllowed;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/api/admin")
public class AdminResource {
@GET
@RolesAllowed("admin")
@Produces(MediaType.TEXT_PLAIN)
public String admin() {
return "granted";
}
}Injection of the SecurityIdentity is supported in both @RequestScoped and @ApplicationScoped contexts.
Configuring the application
The OpenID Connect extension allows you to define the adapter configuration using the application.properties file which should be located at the src/main/resources directory.
Configuration property fixed at build time - All other configuration properties are overridable at runtime
Type |
Default |
|
|---|---|---|
If DevServices has been explicitly enabled or disabled. When DevServices is enabled Quarkus will attempt to automatically configure and start Keycloak when running in Dev or Test mode and when Docker is running. Environment variable: |
boolean |
|
The container image name to use, for container based DevServices providers. Image with a Quarkus based distribution is used by default. Image with a WildFly based distribution can be selected instead, for example: 'quay.io/keycloak/keycloak:19.0.1-legacy'. Note Keycloak Quarkus and Keycloak WildFly images are initialized differently. By default, Dev Services for Keycloak will assume it is a Keycloak Quarkus image if the image version does not end with a '-legacy' string. Set 'quarkus.keycloak.devservices.keycloak-x-image' to override this check. Environment variable: |
string |
|
If Keycloak-X image is used. By default, Dev Services for Keycloak will assume a Keycloak-X image is used if the image name contains a 'keycloak-x' string. Set 'quarkus.keycloak.devservices.keycloak-x-image' to override this check which may be necessary if you build custom Keycloak-X or Keycloak images. You do not need to set this property if the default check works. Environment variable: |
boolean |
|
Indicates if the Keycloak container managed by Quarkus Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services for Keycloak starts a new container.

This property will be used to create the Keycloak users if the realm file pointed to by the 'realm-path' property does not exist. Environment variable: |
|
|
The Keycloak user roles. If this map is empty then a user named 'alice' will get 'admin' and 'user' roles and all other users will get a 'user' role. This property will be used to create the Keycloak roles if the realm file pointed to by the 'realm-path' property does not exist. Environment variable: |

List of paths to claims containing an array of groups. Each path starts from the top level JWT JSON object and can contain multiple segments where each segment represents a JSON object name only, example: "realm/groups". Use double quotes with the namespace qualified claim names. This property can be used if a token has no 'groups' claim but has the groups set in one or more different claims. Environment variable: |
list of string |
|
Separator for splitting a string which may contain multiple group values. It will only be used if the "role-claim-path" property points to one or more custom claims whose values are strings.

Otherwise, the local session will be invalidated and the user redirected to the OpenID Provider to re-authenticate. In this case the user may not be challenged again if the OIDC provider session is still active. For this option be effective the Environment variable: |
boolean |
|
Refresh token time skew in seconds. If this property is enabled then the configured number of seconds is added to the current time when checking whether the access token should be refreshed. If the sum is greater than this access token’s expiration time then a refresh is going to happen. This property will be ignored if the 'refresh-expired' property is not enabled. Environment variable: |
||
Forced JWK set refresh interval in minutes. Environment variable: |
|
|
Custom HTTP header that contains a bearer token. This option is valid only when the application is of type Environment variable: |
string |
|
Decryption key location. JWT tokens can be inner-signed and encrypted by OpenId Connect providers. However, it is not always possible to remotely introspect such tokens because the providers may not control the private decryption keys. In such cases set this property to point to the file containing the decryption private key in PEM or JSON Web Key (JWK) format. Note that if a 'private_key_jwt' client authentication method is used then the private key which is used to sign client authentication JWT tokens will be used to try to decrypt an encrypted ID token if this property is not set. Environment variable: |
string |
|
Allow the remote introspection of JWT tokens when no matching JWK key is available. Note this property is set to 'true' by default for backward-compatibility reasons and will be set to Environment variable: |
boolean |
|
Require that JWT tokens are only introspected remotely. Environment variable: |
boolean |
|
Allow the remote introspection of the opaque tokens. Set this property to 'false' if only JWT tokens are expected. Environment variable: |

string |
|
Relative path of the application endpoint where the user should be redirected to after logging out from the OpenID Connect Provider. This endpoint URI must be properly registered at the OpenID Connect Provider as a valid redirect URI. Environment variable: |
string |
|
Name of the post logout URI parameter which will be added as a query parameter to the logout redirect URI. Environment variable: |
string |
|
The relative path of the Back-Channel Logout endpoint at the application. Environment variable: |
string |
|
Authorization code flow response mode Environment variable: |
|
|
Relative path for calculating a "redirect_uri" query parameter. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if the current request URI is 'https://localhost:8080/service' then a 'redirect_uri' parameter will be set to 'https://localhost:8080/' if this property is set to '/' and be the same as the request URI if this property has not been configured. Note the original request URI will be restored after the user has authenticated if 'restorePathAfterRedirect' is set to 'true'. Environment variable: |
string |
|
If this property is set to 'true' then the original request URI which was used before the authentication will be restored after the user has been redirected back to the application. Note if Environment variable: |
boolean |
|
Remove the query parameters such as 'code' and 'state' set by the OIDC server on the redirect URI after the user has authenticated by redirecting a user to the same URI but without the query parameters. Environment variable: |
boolean |
|
Relative path to the public endpoint which will process the error response from the OIDC authorization endpoint. If the user authentication has failed then the OIDC provider will return an 'error' and an optional 'error_description' parameters, instead of the expected authorization 'code'. If this property is set then the user will be redirected to the endpoint which can return a user-friendly error description page. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if it is set as '/error' and the current request URI is 'https://localhost:8080/callback?error=invalid_scope' then a redirect will be made to 'https://localhost:8080/error?error=invalid_scope'. If this property is not set then HTTP 401 status will be returned in case of the user authentication failure. Environment variable: |
string |
|
Both ID and access tokens are fetched from the OIDC provider as part of the authorization code flow. ID token is always verified on every user request as the primary token which is used to represent the principal and extract the roles. Access token is not verified by default since it is meant to be propagated to the downstream services. The verification of the access token should be enabled if it is injected as a JWT token. Access tokens obtained as part of the code flow will always be verified if Environment variable: |
boolean |
|
Force 'https' as the 'redirect_uri' parameter scheme when running behind an SSL terminating reverse proxy. This property, if enabled, will also affect the logout Environment variable: |
boolean |
|
List of scopes Environment variable: |
list of string |
|
Add the 'openid' scope automatically to the list of scopes. This is required for OpenId Connect providers but will not work for OAuth2 providers such as Twitter OAuth2 which does not accept that scope and throws an error. Environment variable: |
boolean |
|
If enabled the state, session and post logout cookies will have their 'secure' parameter set to 'true' when HTTP is used. It may be necessary when running behind an SSL terminating reverse proxy. The cookies will always be secure if HTTPS is used even if this property is set to false. Environment variable: |
boolean |
|
Cookie name suffix. For example, a session cookie name for the default OIDC tenant is 'q_session' but can be changed to 'q_session_test' if this property is set to 'test'. Environment variable: |
string |
|
Cookie path parameter value which, if set, will be used to set a path parameter for the session, state and post logout cookies. The Environment variable: |
string |
|
Cookie path header parameter value which, if set, identifies the incoming HTTP header whose value will be used to set a path parameter for the session, state and post logout cookies. If the header is missing then the Environment variable: |
string |
|
Cookie domain parameter value which, if set, will be used for the session, state and post logout cookies. Environment variable: |
string |
|
If this property is set to 'true' then an OIDC UserInfo endpoint will be called. Environment variable: |
boolean |
|
Session age extension in minutes. The user session age property is set to the value of the ID token life-span by default and the user will be redirected to the OIDC provider to re-authenticate once the session has expired. If this property is set to a non-zero value then the expired ID token can be refreshed before the session has expired. This property will be ignored if the Environment variable: |
|
|
If this property is set to 'true' then a normal 302 redirect response will be returned if the request was initiated via JavaScript API such as XMLHttpRequest or Fetch and the current user needs to be (re)authenticated which may not be desirable for Single Page Applications since it automatically following the redirect may not work given that OIDC authorization endpoints typically do not support CORS. If this property is set to Environment variable: |
boolean |
|
Requires that ID token is available when the authorization code flow completes. Disable this property only when you need to use the authorization code flow with OAuth2 providers which do not return ID token - an internal IdToken will be generated in such cases. Environment variable: |
boolean |
|
Requires that a Proof Key for Code Exchange (PKCE) is used. Environment variable: |
boolean |
|
Secret which will be used to encrypt a Proof Key for Code Exchange (PKCE) code verifier in the code flow state. This secret must be set if PKCE is required but no client secret is set. The length of the secret which will be used to encrypt the code verifier must be 32 characters long. Environment variable: |
string |
|
Default TokenStateManager strategy. Environment variable: |
|
|
Default TokenStateManager keeps all tokens (ID, access and refresh) returned in the authorization code grant response in a single session cookie by default. Enable this property to minimize a session cookie size Environment variable: |
boolean |
|
Requires that the tokens are encrypted before being stored in the cookies. Environment variable: |
boolean |
|
Secret which will be used to encrypt the tokens. This secret must be set if the token encryption is required but no client secret is set. The length of the secret which will be used to encrypt the tokens must be 32 characters long. Environment variable: |
string |
|
Allow caching the token introspection data. Note enabling this property does not enable the cache itself but only permits to cache the token introspection for a given tenant. If the default token cache can be used then please see Environment variable: |
boolean |
|
Allow caching the user info data. Note enabling this property does not enable the cache itself but only permits to cache the user info data for a given tenant. If the default token cache can be used then please see Environment variable: |
boolean |
|
Allow inlining UserInfo in IdToken instead of caching it in the token cache. This property is only checked when an internal IdToken is generated when Oauth2 providers do not return IdToken. Inlining UserInfo in the generated IdToken allows to store it in the session cookie and avoids introducing a cached state. Environment variable: |
boolean |
|
Well known OpenId Connect provider identifier Environment variable: |
|
|
Maximum number of cache entries. Set it to a positive value if the cache has to be enabled. Environment variable: |
int |

|
Refresh token time skew in seconds. If this property is enabled then the configured number of seconds is added to the current time when checking whether the access token should be refreshed. If the sum is greater than this access token’s expiration time then a refresh is going to happen. This property will be ignored if the 'refresh-expired' property is not enabled. Environment variable: |

Custom HTTP header that contains a bearer token. This option is valid only when the application is of type Environment variable: |
string |
|
Decryption key location. JWT tokens can be inner-signed and encrypted by OpenId Connect providers. However, it is not always possible to remotely introspect such tokens because the providers may not control the private decryption keys. In such cases set this property to point to the file containing the decryption private key in PEM or JSON Web Key (JWK) format. Note that if a 'private_key_jwt' client authentication method is used then the private key which is used to sign client authentication JWT tokens will be used to try to decrypt an encrypted ID token if this property is not set. Environment variable: |
string |
|
Allow the remote introspection of JWT tokens when no matching JWK key is available. Note this property is set to 'true' by default for backward-compatibility reasons and will be set to Environment variable: |

string |
|
Authorization code flow response mode Environment variable: |
|
|
Relative path for calculating a "redirect_uri" query parameter. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if the current request URI is 'https://localhost:8080/service' then a 'redirect_uri' parameter will be set to 'https://localhost:8080/' if this property is set to '/' and be the same as the request URI if this property has not been configured. Note the original request URI will be restored after the user has authenticated if 'restorePathAfterRedirect' is set to 'true'. Environment variable: |
string |
|
If this property is set to 'true' then the original request URI which was used before the authentication will be restored after the user has been redirected back to the application. Note if Environment variable: |
boolean |
|
Remove the query parameters such as 'code' and 'state' set by the OIDC server on the redirect URI after the user has authenticated by redirecting a user to the same URI but without the query parameters. Environment variable: |
boolean |
|
Relative path to the public endpoint which will process the error response from the OIDC authorization endpoint. If the user authentication has failed then the OIDC provider will return an 'error' and an optional 'error_description' parameters, instead of the expected authorization 'code'. If this property is set then the user will be redirected to the endpoint which can return a user-friendly error description page. It has to start from a forward slash and will be appended to the request URI’s host and port. For example, if it is set as '/error' and the current request URI is 'https://localhost:8080/callback?error=invalid_scope' then a redirect will be made to 'https://localhost:8080/error?error=invalid_scope'. If this property is not set then HTTP 401 status will be returned in case of the user authentication failure. Environment variable: |
string |
|
Both ID and access tokens are fetched from the OIDC provider as part of the authorization code flow. ID token is always verified on every user request as the primary token which is used to represent the principal and extract the roles. Access token is not verified by default since it is meant to be propagated to the downstream services. The verification of the access token should be enabled if it is injected as a JWT token. Access tokens obtained as part of the code flow will always be verified if Environment variable: |

|
Additional properties which will be added as the query parameters to the authentication redirect URI. Environment variable: |
|
|
If enabled the state, session and post logout cookies will have their 'secure' parameter set to 'true' when HTTP is used. It may be necessary when running behind an SSL terminating reverse proxy. The cookies will always be secure if HTTPS is used even if this property is set to false. Environment variable: |

Cookie domain parameter value which, if set, will be used for the session, state and post logout cookies. Environment variable: |
string |
|
If this property is set to 'true' then an OIDC UserInfo endpoint will be called. Environment variable: |
boolean |
|
Session age extension in minutes. The user session age property is set to the value of the ID token life-span by default and the user will be redirected to the OIDC provider to re-authenticate once the session has expired. If this property is set to a non-zero value then the expired ID token can be refreshed before the session has expired. This property will be ignored if the Environment variable: |
|
|
If this property is set to 'true' then a normal 302 redirect response will be returned if the request was initiated via JavaScript API such as XMLHttpRequest or Fetch and the current user needs to be (re)authenticated which may not be desirable for Single Page Applications since it automatically following the redirect may not work given that OIDC authorization endpoints typically do not support CORS. If this property is set to Environment variable: |
boolean |
|
Requires that ID token is available when the authorization code flow completes. Disable this property only when you need to use the authorization code flow with OAuth2 providers which do not return ID token - an internal IdToken will be generated in such cases. Environment variable: |

Requires that a Proof Key for Code Exchange (PKCE) is used. Environment variable: |
boolean |
|
Secret which will be used to encrypt a Proof Key for Code Exchange (PKCE) code verifier in the code flow state. This secret must be set if PKCE is required but no client secret is set.

Default TokenStateManager keeps all tokens (ID, access and refresh) returned in the authorization code grant response in a single session cookie by default. Enable this property to minimize a session cookie size Environment variable: |
boolean |
|
Requires that the tokens are encrypted before being stored in the cookies. Environment variable: |
boolean |

Allow caching the token introspection data. Note enabling this property does not enable the cache itself but only permits to cache the token introspection for a given tenant. If the default token cache can be used then please see Environment variable: |
boolean |
|
Allow caching the user info data. Note enabling this property does not enable the cache itself but only permits to cache the user info data for a given tenant. If the default token cache can be used then please see Environment variable: |
boolean |
|
Allow inlining UserInfo in IdToken instead of caching it in the token cache. This property is only checked when an internal IdToken is generated when Oauth2 providers do not return IdToken. Inlining UserInfo in the generated IdToken allows to store it in the session cookie and avoids introducing a cached state. Environment variable: |
boolean |

About the Duration format
The format for durations uses the standard You can also provide duration values starting with a number.
In this case, if the value consists only of a number, the converter treats the value as seconds.
Otherwise, |
Example configuration:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=backend-service
quarkus.oidc.credentials.secret=secret
# Tell Dev Services for Keycloak to import the realm file
# This property is not effective when running the application in JVM or Native modes
quarkus.keycloak.devservices.realm-path=quarkus-realm.json
Adding a %prod. profile prefix to quarkus.oidc.auth-server-url ensures that Dev Services for Keycloak will launch a container for you when the application is run in a dev mode. See Running the Application in Dev mode section below for more information.
|
Starting and Configuring the Keycloak Server
Do not start the Keycloak server when you run the application in a dev mode - Dev Services for Keycloak will launch a container. See Running the Application in Dev mode section below for more information. Make sure to put the realm configuration file on the classpath (target/classes directory) so that it gets imported automatically when running in dev mode - unless you have already built a complete solution in which case this realm file will be added to the classpath during the build.
|
To start a Keycloak Server you can use Docker and just run the following command:
docker run --name keycloak -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=admin -p 8180:8080 quay.io/keycloak/keycloak:{keycloak.version} start-devwhere keycloak.version should be set to 17.0.0 or higher.
You should be able to access your Keycloak Server at localhost:8180.
Log in as the admin user to access the Keycloak Administration Console. Username should be admin and password admin.
Import the realm configuration file to create a new realm. For more details, see the Keycloak documentation about how to create a new realm.
If you want to use the Keycloak Admin Client to configure your server from your application you need to include the
either quarkus-keycloak-admin-client or the quarkus-keycloak-admin-client-reactive (if the application uses quarkus-rest-client-reactive) extension.
See the Quarkus Keycloak Admin Client guide for more information.

Running the Application in Dev mode
To run the application in a dev mode, use:
quarkus dev./mvnw quarkus:dev./gradlew --console=plain quarkusDevDev Services for Keycloak will launch a Keycloak container and import a quarkus-realm.json.
Open a Dev UI available at /q/dev and click on a Provider: Keycloak link in an OpenID Connect Dev UI card.
You will be asked to log in into a Single Page Application provided by OpenID Connect Dev UI:
-
Login as
alice(password:alice) who has auserrole-
accessing
/api/adminwill return403 -
accessing
/api/users/mewill return200
-
-
Logout and login as

Running the Application in JVM mode
When you’re done playing with the dev mode" you can run it as a standard Java application.
First compile it:
quarkus build./mvnw install./gradlew buildThen run it:
java -jar target/quarkus-app/quarkus-run.jarRunning the Application in Native Mode
This same demo can be compiled into native code: no modifications required.
This implies that you no longer need to install a JVM on your production environment, as the runtime technology is included in the produced binary, and optimized to run with minimal resource overhead.
Compilation will take a bit longer, so this step is disabled by default;
let’s build again by enabling the native profile:
quarkus build --native./mvnw install -Dnative./gradlew build -Dquarkus.package.type=nativeAfter getting a cup of coffee, you’ll be able to run this binary directly:
./target/security-openid-connect-quickstart-1.0.0-SNAPSHOT-runnerTesting the Application
See Running the Application in Dev mode section above about testing your application in a dev mode.
You can test the application launched in JVM or Native modes with curl.
The application is using bearer token authorization and the first thing to do is obtain an access token from the Keycloak Server in order to access the application resources:
export access_token=$(\
curl --insecure -X POST http://localhost:8180/realms/quarkus/protocol/openid-connect/token \
--user backend-service:secret \
-H 'content-type: application/x-www-form-urlencoded' \
-d 'username=alice&password=alice&grant_type=password' | jq --raw-output '.access_token' \
)The example above obtains an access token for user alice.
Any user is allowed to access the
http://localhost:8080/api/users/me endpoint
which basically returns a JSON payload with details about the user.
curl -v -X GET \
http://localhost:8080/api/users/me \
-H "Authorization: Bearer "$access_tokenThe http://localhost:8080/api/admin endpoint can only be accessed by users with the admin role. If you try to access this endpoint with the
previously issued access token, you should get a 403 response
from the server.
curl -v -X GET \
http://localhost:8080/api/admin \
-H "Authorization: Bearer "$access_tokenIn order to access the admin endpoint you should obtain a token for the admin user:
export access_token=$(\
curl --insecure -X POST http://localhost:8180/realms/quarkus/protocol/openid-connect/token \
--user backend-service:secret \
-H 'content-type: application/x-www-form-urlencoded' \
-d 'username=admin&password=admin&grant_type=password' | jq --raw-output '.access_token' \
)Please also see the Dev Services for Keycloak section below about writing the integration tests which depend on Dev Services for Keycloak.
Reference Guide
Accessing JWT claims
If you need to access JWT token claims then you can inject JsonWebToken:
package org.acme.security.openid.connect;
import org.eclipse.microprofile.jwt.JsonWebToken;
import javax.inject.Inject;
import javax.annotation.security.RolesAllowed;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
@Path("/api/admin")
public class AdminResource {
@Inject
JsonWebToken jwt;
@GET
@RolesAllowed("admin")
@Produces(MediaType.TEXT_PLAIN)
public String admin() {
return "Access for subject " + jwt.getSubject() + " is granted";
}
}Injection of JsonWebToken is supported in @ApplicationScoped, @Singleton and @RequestScoped scopes however the use of @RequestScoped is required if the individual claims are injected as simple types, please see Support Injection Scopes for JsonWebToken and Claims for more details.
User Info
Set quarkus.oidc.authentication.user-info-required=true if a UserInfo JSON object from the OIDC userinfo endpoint has to be requested.
A request will be sent to the OpenID Provider UserInfo endpoint and an io.quarkus.oidc.UserInfo (a simple javax.json.JsonObject wrapper) object will be created.
io.quarkus.oidc.UserInfo can be either injected or accessed as a SecurityIdentity userinfo attribute.
Configuration Metadata
The current tenant’s discovered OpenID Connect Configuration Metadata is represented by io.quarkus.oidc.OidcConfigurationMetadata and can be either injected or accessed as a SecurityIdentity configuration-metadata attribute.
The default tenant’s OidcConfigurationMetadata is injected if the endpoint is public.
Token Claims And SecurityIdentity Roles
SecurityIdentity roles can be mapped from the verified JWT access tokens as follows:
-
If
quarkus.oidc.roles.role-claim-pathproperty is set and matching array or string claims are found then the roles are extracted from these claims. For example,customroles,customroles/array,scope,"http://namespace-qualified-custom-claim"/roles,"http://namespace-qualified-roles", etc. -
If
groupsclaim is available then its value is used -
If
realm_access/rolesorresource_access/client_id/roles(whereclient_idis the value of thequarkus.oidc.client-idproperty) claim is available then its value is used. This check supports the tokens issued by Keycloak
If the token is opaque (binary) then a scope property from the remote token introspection response will be used.
If UserInfo is the source of the roles then set quarkus.oidc.authentication.user-info-required=true and quarkus.oidc.roles.source=userinfo, and if needed, quarkus.oidc.roles.role-claim-path.
Additionally, a custom SecurityIdentityAugmentor can also be used to add the roles as documented here.
Token Verification And Introspection
If the token is a JWT token then, by default, it will be verified with a JsonWebKey (JWK) key from a local JsonWebKeySet retrieved from the OpenID Connect Provider’s JWK endpoint. The token’s key identifier kid header value will be used to find the matching JWK key.
If no matching JWK is available locally then JsonWebKeySet will be refreshed by fetching the current key set from the JWK endpoint. The JsonWebKeySet refresh can be repeated only after the quarkus.oidc.token.forced-jwk-refresh-interval (default is 10 minutes) expires.
If no matching JWK is available after the refresh then the JWT token will be sent to the OpenID Connect Provider’s token introspection endpoint.
If the token is opaque (it can be a binary token or an encrypted JWT token) then it will always be sent to the OpenID Connect Provider’s token introspection endpoint.
If you work with JWT tokens only and expect that a matching JsonWebKey will always be available (possibly after a key set refresh) then you should disable the token introspection:
quarkus.oidc.token.allow-jwt-introspection=false
quarkus.oidc.token.allow-opaque-token-introspection=falseHowever, there could be cases where JWT tokens must be verified via the introspection only. It can be forced by configuring an introspection endpoint address only, for example, in case of Keycloak you can do it like this:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.discovery-enabled=false
# Token Introspection endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/tokens/introspect
quarkus.oidc.introspection-path=/protocol/openid-connect/tokens/introspectAn advantage of this indirect enforcement of JWT tokens being only introspected remotely is that two remote call are avoided: a remote OIDC metadata discovery call followed by another remote call fetching the verification keys which will not be used, while its disavantage is that the users need to know the introspection endpoint address and configure it manually.
The alternative approach is to allow discovering the OIDC metadata (which is a default option) but require that only the remote JWT introspection is performed:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.token.require-jwt-introspection-only=trueAn advantage of this approach is that the configuration is simple and easy to understand, while its disavantage is that a remote OIDC metadata discovery call is required to discover an introspection endpoint address (though the verification keys will also not be fetched).
Note that io.quarkus.oidc.TokenIntrospection (a simple javax.json.JsonObject wrapper) object will be created and can be either injected or accessed as a SecurityIdentity introspection attribute if either JWT or opaque token has been successfully introspected.
Token Introspection and UserInfo Cache
All opaque and sometimes JWT Bearer access tokens have to be remotely introspected. If UserInfo is also required then the same access token will be used to do a remote call to OpenID Connect Provider again. So, if UserInfo is required and the current access token is opaque then for every such token there will be 2 remote calls done - one to introspect it and one to get UserInfo with it, and if the token is JWT then usually only a single remote call will be needed - to get UserInfo with it.
The cost of making up to 2 remote calls per every incoming bearer or code flow access token can sometimes be problematic.
If it is the case in your production then it can be recommended that the token introspection and UserInfo data are cached for a short period of time, for example, for 3 or 5 minutes.
quarkus-oidc provides quarkus.oidc.TokenIntrospectionCache and quarkus.oidc.UserInfoCache interfaces which can be used to implement @ApplicationScoped cache implementation which can be used to store and retrieve quarkus.oidc.TokenIntrospection and/or quarkus.oidc.UserInfo objects, for example:
@ApplicationScoped
@AlternativePriority(1)
public class CustomIntrospectionUserInfoCache implements TokenIntrospectionCache, UserInfoCache {
...
}Each OIDC tenant can either permit or deny storing its quarkus.oidc.TokenIntrospection and/or quarkus.oidc.UserInfo data with boolean quarkus.oidc."tenant".allow-token-introspection-cache and quarkus.oidc."tenant".allow-user-info-cache properties.
Additionally, quarkus-oidc provides a simple default memory based token cache which implements both quarkus.oidc.TokenIntrospectionCache and quarkus.oidc.UserInfoCache interfaces.
It can be activated and configured as follows:
# 'max-size' is 0 by default so the cache can be activated by setting 'max-size' to a positive value.
quarkus.oidc.token-cache.max-size=1000
# 'time-to-live' specifies how long a cache entry can be valid for and will be used by a cleanup timer.
quarkus.oidc.token-cache.time-to-live=3M
# 'clean-up-timer-interval' is not set by default so the cleanup timer can be activated by setting 'clean-up-timer-interval'.
quarkus.oidc.token-cache.clean-up-timer-interval=1MThe default cache uses a token as a key and each entry can have TokenIntrospection and/or UserInfo. It will only keep up to a max-size number of entries. If the cache is full when a new entry is to be added then an attempt will be made to find a space for it by removing a single expired entry. Additionally, the cleanup timer, if activated, will periodically check for the expired entries and remove them.
Please experiment with the default cache implementation or register a custom one.
JSON Web Token Claim Verification
Once the bearer JWT token’s signature has been verified and its expires at (exp) claim has been checked, the iss (issuer) claim value is verified next.
By default, the iss claim value is compared to the issuer property which may have been discovered in the well-known provider configuration.
But if quarkus.oidc.token.issuer property is set then the iss claim value is compared to it instead.
In some cases, this iss claim verification may not work. For example, if the discovered issuer property contains an internal HTTP/IP address while the token iss claim value contains an external HTTP/IP address. Or when a discovered issuer property contains the template tenant variable but the token iss claim value has the complete tenant-specific issuer value.
In such cases you may want to consider skipping the issuer verification by setting quarkus.oidc.token.issuer=any. Please note that it is not recommended and should be avoided unless no other options are available:
-
If you work with Keycloak and observe the issuer verification errors due to the different host addresses then configure Keycloak with a
KEYCLOAK_FRONTEND_URLproperty to ensure the same host address is used. -
If the
issproperty is tenant specific in a multi-tenant deployment then you can use theSecurityIdentitytenant-idattribute to check the issuer is correct in the endpoint itself or the custom JAX-RS filter, for example:
import javax.inject.Inject;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.ext.Provider;
import org.eclipse.microprofile.jwt.JsonWebToken;
import io.quarkus.oidc.OidcConfigurationMetadata;
import io.quarkus.security.identity.SecurityIdentity;
@Provider
public class IssuerValidator implements ContainerRequestFilter {
@Inject
OidcConfigurationMetadata configMetadata;
@Inject JsonWebToken jwt;
@Inject SecurityIdentity identity;
public void filter(ContainerRequestContext requestContext) {
String issuer = configMetadata.getIssuer().replace("{tenant-id}", identity.getAttribute("tenant-id"));
if (!issuer.equals(jwt.getIssuer())) {
requestContext.abortWith(Response.status(401).build());
}
}
}Note it is also recommended to use quarkus.oidc.token.audience property to verify the token aud (audience) claim value.
Single Page Applications
Single Page Application (SPA) typically uses XMLHttpRequest(XHR) and the JavaScript utility code provided by the OpenID Connect provider to acquire a bearer token and use it
to access Quarkus service applications.
For example, here is how you can use keycloak.js to authenticate the users and refresh the expired tokens from the SPA:
<html>
<head>
<title>keycloak-spa</title>
<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>
<script src="http://localhost:8180/js/keycloak.js"></script>
<script>
var keycloak = new Keycloak();
keycloak.init({onLoad: 'login-required'}).success(function () {
console.log('User is now authenticated.');
}).error(function () {
window.location.reload();
});
function makeAjaxRequest() {
axios.get("/api/hello", {
headers: {
'Authorization': 'Bearer ' + keycloak.token
}
})
.then( function (response) {
console.log("Response: ", response.status);
}).catch(function (error) {
console.log('refreshing');
keycloak.updateToken(5).then(function () {
console.log('Token refreshed');
}).catch(function () {
console.log('Failed to refresh token');
window.location.reload();
});
});
}
</script>
</head>
<body>
<button onclick="makeAjaxRequest()">Request</button>
</body>
</html>Cross Origin Resource Sharing
If you plan to consume your OpenID Connect service application from a Single Page Application running on a different domain, you will need to configure CORS (Cross-Origin Resource Sharing). Please read the HTTP CORS documentation for more details.
Provider Endpoint configuration
OIDC service application needs to know OpenID Connect provider’s token, JsonWebKey (JWK) set and possibly UserInfo and introspection endpoint addresses.
By default, they are discovered by adding a /.well-known/openid-configuration path to the configured quarkus.oidc.auth-server-url.
Alternatively, if the discovery endpoint is not available, or if you would like to save on the discovery endpoint round-trip, you can disable the discovery and configure them with relative path values, for example:
quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.discovery-enabled=false
# Token endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/token
quarkus.oidc.token-path=/protocol/openid-connect/token
# JWK set endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/certs
quarkus.oidc.jwks-path=/protocol/openid-connect/certs
# UserInfo endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/userinfo
quarkus.oidc.user-info-path=/protocol/openid-connect/userinfo
# Token Introspection endpoint: http://localhost:8180/realms/quarkus/protocol/openid-connect/tokens/introspect
quarkus.oidc.introspection-path=/protocol/openid-connect/tokens/introspectToken Propagation
Please see Token Propagation section about the Bearer access token propagation to the downstream services.
Oidc Provider Client Authentication
quarkus.oidc.runtime.OidcProviderClient is used when a remote request to an OpenID Connect Provider has to be done. If the bearer token has to be introspected then OidcProviderClient has to authenticate to the OpenID Connect Provider. Please see OidcProviderClient Authentication for more information about all the supported authentication options.
Testing
Start by adding the following dependencies to your test project:
<dependency>
<groupId>io.rest-assured</groupId>
<artifactId>rest-assured</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-junit5</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.rest-assured:rest-assured")
testImplementation("io.quarkus:quarkus-junit5")Wiremock
Add the following dependencies to your test project:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-oidc-server</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-oidc-server")Prepare the REST test endpoint, set application.properties, for example:
# keycloak.url is set by OidcWiremockTestResource
quarkus.oidc.auth-server-url=${keycloak.url}/realms/quarkus/
quarkus.oidc.client-id=quarkus-service-app
quarkus.oidc.application-type=serviceand finally write the test code, for example:
import static org.hamcrest.Matchers.equalTo;
import java.util.Set;
import org.junit.jupiter.api.Test;
import io.quarkus.test.common.QuarkusTestResource;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.oidc.server.OidcWiremockTestResource;
import io.restassured.RestAssured;
import io.smallrye.jwt.build.Jwt;
@QuarkusTest
@QuarkusTestResource(OidcWiremockTestResource.class)
public class BearerTokenAuthorizationTest {
@Test
public void testBearerToken() {
RestAssured.given().auth().oauth2(getAccessToken("alice", Set.of("user")))
.when().get("/api/users/me")
.then()
.statusCode(200)
// the test endpoint returns the name extracted from the injected SecurityIdentity Principal
.body("userName", equalTo("alice"));
}
private String getAccessToken(String userName, Set<String> groups) {
return Jwt.preferredUserName(userName)
.groups(groups)
.issuer("https://server.example.com")
.audience("https://service.example.com")
.sign();
}
}Note that the quarkus-test-oidc-server extension includes a signing RSA private key file in a JSON Web Key (JWK) format and points to it with a smallrye.jwt.sign.key.location configuration property. It allows to use a no argument sign() operation to sign the token.
Testing your quarkus-oidc service application with OidcWiremockTestResource provides the best coverage as even the communication channel is tested against the Wiremock HTTP stubs.
OidcWiremockTestResource will be enhanced going forward to support more complex Bearer token test scenarios.
If there is an immediate need for a test to define Wiremock stubs not currently supported by OidcWiremockTestResource
one can do so via a WireMockServer instance injected into the test class, for example:
|
|
package io.quarkus.it.keycloak;
import static com.github.tomakehurst.wiremock.client.WireMock.matching;
import static org.hamcrest.Matchers.equalTo;
import org.junit.jupiter.api.Test;
import com.github.tomakehurst.wiremock.WireMockServer;
import com.github.tomakehurst.wiremock.client.WireMock;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.oidc.server.OidcWireMock;
import io.restassured.RestAssured;
@QuarkusTest
public class CustomOidcWireMockStubTest {
@OidcWireMock
WireMockServer wireMockServer;
@Test
public void testInvalidBearerToken() {
wireMockServer.stubFor(WireMock.post("/auth/realms/quarkus/protocol/openid-connect/token/introspect")
.withRequestBody(matching(".*token=invalid_token.*"))
.willReturn(WireMock.aResponse().withStatus(400)));
RestAssured.given().auth().oauth2("invalid_token").when()
.get("/api/users/me/bearer")
.then()
.statusCode(401)
.header("WWW-Authenticate", equalTo("Bearer"));
}
}Dev Services for Keycloak
Using Dev Services for Keycloak is recommended for the integration testing against Keycloak.
Dev Services for Keycloak will launch and initialize a test container: it will create a quarkus realm, a quarkus-app client (secret secret) and add alice (admin and user roles) and bob (user role) users, where all of these properties can be customized.
First you need to add the following dependency:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-keycloak-server</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-keycloak-server")which provides a utility class io.quarkus.test.keycloak.client.KeycloakTestClient you can use in tests for acquiring the access tokens.
Next prepare your application.properties. You can start with a completely empty application.properties as Dev Services for Keycloak will register quarkus.oidc.auth-server-url pointing to the running test container as well as quarkus.oidc.client-id=quarkus-app and quarkus.oidc.credentials.secret=secret.
But if you already have all the required quarkus-oidc properties configured then you only need to associate quarkus.oidc.auth-server-url with the prod profile for `Dev Services for Keycloak`to start a container, for example:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkusIf a custom realm file has to be imported into Keycloak before running the tests then you can configure Dev Services for Keycloak as follows:
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.keycloak.devservices.realm-path=quarkus-realm.jsonFinally, write your test which will be executed in JVM mode:
package org.acme.security.openid.connect;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.keycloak.client.KeycloakTestClient;
import io.restassured.RestAssured;
import org.junit.jupiter.api.Test;
@QuarkusTest
public class BearerTokenAuthenticationTest {
KeycloakTestClient keycloakClient = new KeycloakTestClient();
@Test
public void testAdminAccess() {
RestAssured.given().auth().oauth2(getAccessToken("alice"))
.when().get("/api/admin")
.then()
.statusCode(200);
RestAssured.given().auth().oauth2(getAccessToken("bob"))
.when().get("/api/admin")
.then()
.statusCode(403);
}
protected String getAccessToken(String userName) {
return keycloakClient.getAccessToken(userName);
}
}and in native mode:
package org.acme.security.openid.connect;
import io.quarkus.test.junit.QuarkusIntegrationTest;
@QuarkusIntegrationTest
public class NativeBearerTokenAuthenticationIT extends BearerTokenAuthenticationTest {
}Please see Dev Services for Keycloak for more information about the way it is initialized and configured.
KeycloakTestResourceLifecycleManager
If you need to do some integration testing against Keycloak then you are encouraged to do it with Dev Services For Keycloak.
Use KeycloakTestResourceLifecycleManager for your tests only if there is a good reason not to use Dev Services for Keycloak.
Start with adding the following dependency:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-keycloak-server</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-keycloak-server")which provides io.quarkus.test.keycloak.server.KeycloakTestResourceLifecycleManager - an implementation of io.quarkus.test.common.QuarkusTestResourceLifecycleManager which starts a Keycloak container.
And configure the Maven Surefire plugin as follows:
<plugin>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<systemPropertyVariables>
<!-- or, alternatively, configure 'keycloak.version' -->
<keycloak.docker.image>${keycloak.docker.image}</keycloak.docker.image>
<!--
Disable HTTPS if required:
<keycloak.use.https>false</keycloak.use.https>
-->
</systemPropertyVariables>
</configuration>
</plugin>(and similarly maven.failsafe.plugin when testing in native image).
Prepare the REST test endpoint, set application.properties, for example:
# keycloak.url is set by KeycloakTestResourceLifecycleManager
quarkus.oidc.auth-server-url=${keycloak.url}/realms/quarkus/
quarkus.oidc.client-id=quarkus-service-app
quarkus.oidc.credentials=secret
quarkus.oidc.application-type=serviceand finally write the test code, for example:
import static io.quarkus.test.keycloak.server.KeycloakTestResourceLifecycleManager.getAccessToken;
import static org.hamcrest.Matchers.equalTo;
import org.hamcrest.Matchers;
import org.junit.jupiter.api.Test;
import io.quarkus.test.common.QuarkusTestResource;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.keycloak.server.KeycloakTestResourceLifecycleManager;
import io.restassured.RestAssured;
@QuarkusTest
@QuarkusTestResource(KeycloakTestResourceLifecycleManager.class)
public class BearerTokenAuthorizationTest {
@Test
public void testBearerToken() {
RestAssured.given().auth().oauth2(getAccessToken("alice"))))
.when().get("/api/users/preferredUserName")
.then()
.statusCode(200)
// the test endpoint returns the name extracted from the injected SecurityIdentity Principal
.body("userName", equalTo("alice"));
}
}KeycloakTestResourceLifecycleManager registers alice and admin users. The user alice has the user role only by default - it can be customized with a keycloak.token.user-roles system property. The user admin has the user and admin roles by default - it can be customized with a keycloak.token.admin-roles system property.
By default, KeycloakTestResourceLifecycleManager uses HTTPS to initialize a Keycloak instance which can be disabled with keycloak.use.https=false.
Default realm name is quarkus and client id - quarkus-service-app - set keycloak.realm and keycloak.service.client system properties to customize the values if needed.
Local Public Key
You can also use a local inlined public key for testing your quarkus-oidc service applications:
quarkus.oidc.client-id=test
quarkus.oidc.public-key=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAlivFI8qB4D0y2jy0CfEqFyy46R0o7S8TKpsx5xbHKoU1VWg6QkQm+ntyIv1p4kE1sPEQO73+HY8+Bzs75XwRTYL1BmR1w8J5hmjVWjc6R2BTBGAYRPFRhor3kpM6ni2SPmNNhurEAHw7TaqszP5eUF/F9+KEBWkwVta+PZ37bwqSE4sCb1soZFrVz/UT/LF4tYpuVYt3YbqToZ3pZOZ9AX2o1GCG3xwOjkc4x0W7ezbQZdC9iftPxVHR8irOijJRRjcPDtA6vPKpzLl6CyYnsIYPd99ltwxTHjr3npfv/3Lw50bAkbT4HeLFxTx4flEoZLKO/g0bAoV2uqBhkA9xnQIDAQAB
smallrye.jwt.sign.key.location=/privateKey.pemcopy privateKey.pem from the integration-tests/oidc-tenancy in the main Quarkus repository and use a test code similar to the one in the Wiremock section above to generate JWT tokens. You can use your own test keys if preferred.
This approach provides a more limited coverage compared to the Wiremock approach - for example, the remote communication code is not covered.
TestSecurity annotation
You can use @TestSecurity and @OidcSecurity annotations for testing the service application endpoint code which depends on the injected JsonWebToken as well as UserInfo and OidcConfigurationMetadata.
Add the following dependency:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-test-security-oidc</artifactId>
<scope>test</scope>
</dependency>testImplementation("io.quarkus:quarkus-test-security-oidc")and write a test code like this one:
import static org.hamcrest.Matchers.is;
import org.junit.jupiter.api.Test;
import io.quarkus.test.common.http.TestHTTPEndpoint;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.security.TestSecurity;
import io.quarkus.test.security.oidc.Claim;
import io.quarkus.test.security.oidc.ConfigMetadata;
import io.quarkus.test.security.oidc.OidcSecurity;
import io.quarkus.test.security.oidc.OidcConfigurationMetadata;
import io.quarkus.test.security.oidc.UserInfo;
import io.restassured.RestAssured;
@QuarkusTest
@TestHTTPEndpoint(ProtectedResource.class)
public class TestSecurityAuthTest {
@Test
@TestSecurity(user = "userOidc", roles = "viewer")
public void testOidc() {
RestAssured.when().get("test-security-oidc").then()
.body(is("userOidc:viewer"));
}
@Test
@TestSecurity(user = "userOidc", roles = "viewer")
@OidcSecurity(claims = {
@Claim(key = "email", value = "user@gmail.com")
}, userinfo = {
@UserInfo(key = "sub", value = "subject")
}, config = {
@ConfigMetadata(key = "issuer", value = "issuer")
})
public void testOidcWithClaimsUserInfoAndMetadata() {
RestAssured.when().get("test-security-oidc-claims-userinfo-metadata").then()
.body(is("userOidc:viewer:user@gmail.com:subject:issuer"));
}
}where ProtectedResource class may look like this:
import io.quarkus.oidc.OidcConfigurationMetadata;
import io.quarkus.oidc.UserInfo;
import org.eclipse.microprofile.jwt.JsonWebToken;
@Path("/service")
@Authenticated
public class ProtectedResource {
@Inject
JsonWebToken accessToken;
@Inject
UserInfo userInfo;
@Inject
OidcConfigurationMetadata configMetadata;
@GET
@Path("test-security-oidc")
public String testSecurityOidc() {
return accessToken.getName() + ":" + accessToken.getGroups().iterator().next();
}
@GET
@Path("test-security-oidc-claims-userinfo-metadata")
public String testSecurityOidcWithClaimsUserInfoMetadata() {
return accessToken.getName() + ":" + accessToken.getGroups().iterator().next()
+ ":" + accessToken.getClaim("email")
+ ":" + userInfo.getString("sub")
+ ":" + configMetadata.get("issuer");
}
}Note that @TestSecurity annotation must always be used and its user property is returned as JsonWebToken.getName() and roles property - as JsonWebToken.getGroups().
@OidcSecurity annotation is optional and can be used to set the additional token claims, as well as UserInfo and OidcConfigurationMetadata properties.
Additionally, if quarkus.oidc.token.issuer property is configured then it will be used as an OidcConfigurationMetadata issuer property value.
If you work with the opaque tokens then you can test them as follows:
import static org.hamcrest.Matchers.is;
import org.junit.jupiter.api.Test;
import io.quarkus.test.common.http.TestHTTPEndpoint;
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.security.TestSecurity;
import io.quarkus.test.security.oidc.OidcSecurity;
import io.quarkus.test.security.oidc.TokenIntrospection;
import io.restassured.RestAssured;
@QuarkusTest
@TestHTTPEndpoint(ProtectedResource.class)
public class TestSecurityAuthTest {
@Test
@TestSecurity(user = "userOidc", roles = "viewer")
@OidcSecurity(introspectionRequired = true,
introspection = {
@TokenIntrospection(key = "email", value = "user@gmail.com")
}
)
public void testOidcWithClaimsUserInfoAndMetadata() {
RestAssured.when().get("test-security-oidc-claims-userinfo-metadata").then()
.body(is("userOidc:viewer:userOidc:viewer"));
}
}where ProtectedResource class may look like this:
import io.quarkus.oidc.TokenIntrospection;
import io.quarkus.security.identity.SecurityIdentity;
@Path("/service")
@Authenticated
public class ProtectedResource {
@Inject
SecurityIdentity securityIdentity;
@Inject
TokenIntrospection introspection;
@GET
@Path("test-security-oidc-opaque-token")
public String testSecurityOidcOpaqueToken() {
return securityIdentity.getPrincipal().getName() + ":" + securityIdentity.getRoles().iterator().next()
+ ":" + introspection.getString("username")
+ ":" + introspection.getString("scope")
+ ":" + introspection.getString("email");
}
}Note that @TestSecurity user and roles attributes are available as TokenIntrospection username and scope properties and you can use io.quarkus.test.security.oidc.TokenIntrospection to add the additional introspection response properties such as an email, etc.
How to check the errors in the logs
Please enable io.quarkus.oidc.runtime.OidcProvider TRACE level logging to see more details about the token verification errors:
quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".level=TRACE
quarkus.log.category."io.quarkus.oidc.runtime.OidcProvider".min-level=TRACEPlease enable io.quarkus.oidc.runtime.OidcRecorder TRACE level logging to see more details about the OidcProvider client initialization errors:
quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".level=TRACE
quarkus.log.category."io.quarkus.oidc.runtime.OidcRecorder".min-level=TRACEExternal and Internal Access to OpenID Connect Provider
Note that the OpenID Connect Provider externally accessible token and other endpoints may have different HTTP(S) URLs compared to the URLs auto-discovered or configured relative to quarkus.oidc.auth-server-url internal URL. For example, if your SPA acquires a token from an external token endpoint address and sends it to Quarkus as a Bearer token then an issuer verification failure may be reported by the endpoint.
In such cases, if you work with Keycloak then please start it with a KEYCLOAK_FRONTEND_URL system property set to the externally accessible base URL.
If you work with other Openid Connect providers then please check your provider’s documentation.
How to use 'client-id' property
quarkus.oidc.client-id property identifies an OpenID Connect Client which requested the current bearer token. It can be an SPA application running in a browser or a Quarkus web-app confidential client application propagating the access token to the Quarkus service application.
This property is required if the service application is expected to introspect the tokens remotely - which is always the case for the opaque tokens.
This property is optional if the local Json Web Key token verification only is used.
Nonetheless, setting this property is encouraged even if the endpoint does not require access to the remote introspection endpoint. The reasons behind it that client-id, if set, can be used to verify the token audience and will also be included in the logs when the token verification fails for the better traceability of the tokens issued to specific clients to be analyzed over a longer period of time.
For example, if your OpenID Connect provider sets a token audience then the following configuration pattern is recommended:
# Set client-id
quarkus.oidc.client-id=quarkus-app
# Token audience claim must contain 'quarkus-app'
quarkus.oidc.token.audience=${quarkus.oidc.client-id}If you set quarkus.oidc.client-id but your endpoint does not require remote access to one of OpenID Connect Provider endpoints (introspection, token acquisition, etc.) then do not set a client secret with the quarkus.oidc.credentials or similar properties as it will not be used.
Note Quarkus web-app applications always require quarkus.oidc.client-id property.
