Quarkus - 認可コードフローのOpenID Connectを使用してWebアプリケーションを保護
Quarkus OIDCエクステンションでQuarkus OpenID Connect（OIDC）の認可コードフローメカニズムを使用して、アプリケーションのHTTPエンドポイントを保護し、堅牢な認証と認可を実現する方法をご覧ください。
For more information, see OIDC code flow mechanism for protecting web applications.

前提条件
このガイドを完成させるには、以下が必要です:
-
約15分
-
IDE
-
JDK 17+がインストールされ、
JAVA_HOMEが適切に設定されていること -
Apache Maven 3.9.9
-
動作するコンテナランタイム(Docker, Podman)
-
使用したい場合は、 Quarkus CLI

ネイティブ実行可能ファイルをビルドしたい場合、MandrelまたはGraalVM（あるいはネイティブなコンテナビルドを使用する場合はDocker）をインストールし、 適切に設定していること
アーキテクチャ
In this example, we build a simple web application with a single page:
-
/index.html
This page is protected, and only authenticated users can access it.
ソリューション
Follow the instructions in the next sections and create the application step by step. Alternatively, you can go right to the completed example.
Clone the Git repository by running the git clone https://github.com/quarkusio/quarkus-quickstarts.git command.
Alternatively, download an archive.
The solution is located in the security-openid-connect-web-authentication-quickstart directory.
1. Maven プロジェクトの作成
First, we need a new project. Create a new project by running the following command:
Windowsユーザーの場合:
-
cmdを使用する場合、（バックスラッシュ
\を使用せず、すべてを同じ行に書かないでください）。 -
Powershellを使用する場合は、
-Dパラメータを二重引用符で囲んでください。例:"-DprojectArtifactId=security-openid-connect-web-authentication-quickstart"
すでにQuarkusプロジェクトが設定されている場合は、プロジェクトのベースディレクトリーで以下のコマンドを実行することで、プロジェクトに oidc エクステンションを追加することができます。
quarkus extension add oidc./mvnw quarkus:add-extension -Dextensions='oidc'./gradlew addExtension --extensions='oidc'This adds the following dependency to your build file:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-oidc</artifactId>
</dependency>implementation("io.quarkus:quarkus-oidc")2. アプリケーションの記述
Let’s write a simple Jakarta REST resource that has all the tokens returned in the authorization code grant response injected:
package org.acme.security.openid.connect.web.authentication;
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import org.eclipse.microprofile.jwt.Claims;
import org.eclipse.microprofile.jwt.JsonWebToken;
import io.quarkus.oidc.IdToken;
import io.quarkus.oidc.RefreshToken;
@Path("/tokens")
public class TokenResource {
/**
* Injection point for the ID token issued by the OpenID Connect provider
*/
@Inject
@IdToken
JsonWebToken idToken;
/**
* Injection point for the access token issued by the OpenID Connect provider
*/
@Inject
JsonWebToken accessToken;
/**
* Injection point for the refresh token issued by the OpenID Connect provider
*/
@Inject
RefreshToken refreshToken;
/**
* Returns the tokens available to the application.
* This endpoint exists only for demonstration purposes.
* Do not expose these tokens in a real application.
*
* @return an HTML page containing the tokens available to the application.
*/
@GET
@Produces("text/html")
public String getTokens() {
StringBuilder response = new StringBuilder().append("<html>")
.append("<body>")
.append("<ul>");
Object userName = this.idToken.getClaim(Claims.preferred_username);
if (userName != null) {
response.append("<li>username: ").append(userName.toString()).append("</li>");
}
Object scopes = this.accessToken.getClaim("scope");
if (scopes != null) {
response.append("<li>scopes: ").append(scopes.toString()).append("</li>");
}
response.append("<li>refresh_token: ").append(refreshToken.getToken() != null).append("</li>");
return response.append("</ul>").append("</body>").append("</html>").toString();
}
}This endpoint has ID, access, and refresh tokens injected.
It returns a preferred_username claim from the ID token, a scope claim from the access token, and a refresh token availability status.
You only need to inject the tokens if the endpoint needs to use the ID token to interact with the currently authenticated user or use the access token to access a downstream service on behalf of this user.
For more information, see the Access ID and Access Tokens section of the reference guide.
3. アプリケーションの設定
The OIDC extension allows you to define the configuration by using the application.properties file in the src/main/resources directory.
%prod.quarkus.oidc.auth-server-url=http://localhost:8180/realms/quarkus
quarkus.oidc.client-id=frontend
quarkus.oidc.credentials.secret=secret
quarkus.oidc.application-type=web-app
quarkus.http.auth.permission.authenticated.paths=/*
quarkus.http.auth.permission.authenticated.policy=authenticatedこれは、アプリケーションへの認証を有効にする際に最もシンプルな設定です。
The quarkus.oidc.client-id property references the client_id issued by the OIDC provider, and the quarkus.oidc.credentials.secret property sets the client secret.
The quarkus.oidc.application-type property is set to web-app to tell Quarkus that you want to enable the OIDC authorization code flow so that your users are redirected to the OIDC provider to authenticate.
Finally, the quarkus.http.auth.permission.authenticated permission is set to tell Quarkus about the paths you want to protect.
In this case, all paths are protected by a policy that ensures only authenticated users can access them.
For more information, see Security Authorization Guide.

When you do not configure a client secret with The The encryption secret is recommended to be 32 chars long. For example, |
4. Keycloakサーバーの起動と設定
Keycloakサーバーを起動するには、Dockerを使用し、以下のコマンドを実行します:
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 is set to 25.0.6 or later.
You can access your Keycloak Server at localhost:8180.
To access the Keycloak Administration Console, log in as the admin user.
The username and password are both admin.
To create a new realm, import the realm configuration file. For more information, see the Keycloak documentation about how to create and configure a new realm.
5. devモードとJVMモードでアプリケーションを実行
アプリケーションを開発モードで実行するには、次を使用します:
quarkus dev./mvnw quarkus:dev./gradlew --console=plain quarkusDev開発モードでアプリケーションを試した後、標準の Java アプリケーションとして実行できます。
まず、コンパイルします:
quarkus build./mvnw install./gradlew buildそして、実行してみてください:
java -jar target/quarkus-app/quarkus-run.jar6. Native モードでアプリケーションを実行
This same demo can be compiled into native code. No modifications are 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 resources.
Compilation takes longer, so this step is turned off by default. You can build again by enabling the native build:
quarkus build --native./mvnw install -Dnative./gradlew build -Dquarkus.native.enabled=trueAfter a while, you can run this binary directly:
./target/security-openid-connect-web-authentication-quickstart-runner7. アプリケーションのテスト
アプリケーションの動作確認は、ブラウザを起動して以下のURLにアクセスしてください:
If everything works as expected, you are redirected to the Keycloak server to authenticate.
To authenticate to the application, enter the following credentials at the Keycloak login page:
-
Username: alice
-
Password: alice
After clicking the Login button, you are redirected back to the application, and a session cookie will be created.
The session for this demo is valid for a short period of time and, on every page refresh, you will be asked to re-authenticate.
For information about how to increase the session timeouts, see the Keycloak session timeout documentation.
For example, you can access the Keycloak Admin console directly from the dev UI by clicking the Keycloak Admin link if you use Dev Services for Keycloak in dev mode:
For more information about writing the integration tests that depend on Dev Services for Keycloak, see the Dev Services for Keycloak section.
まとめ
You have learned how to set up and use the OIDC authorization code flow mechanism to protect and test application HTTP endpoints. After you have completed this tutorial, explore OIDC Bearer token authentication and other authentication mechanisms.
