4.5. 编写应用程序

我们编写一个简单的 Jakarta REST 资源，该资源在授权代码授予响应中返回的所有令牌：

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();
   }
}

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();
   }
}

此端点注入了 ID、访问和刷新令牌。它从 ID 令牌、访问令牌中的 范围 声明和刷新令牌可用性状态返回 preferred_username 声明。

只有在端点需要使用 ID 令牌与当前经过身份验证的用户交互时，您只需要注入令牌，或使用访问令牌代表此用户访问下游服务。

如需更多信息，请参阅参考指南中的访问 ID 和访问令牌部分。
