Keycloak-Uma配置

Posted 2023-01-30

当尝试使用keycloak java api即时通讯收到此错误时：

Exception in thread "main" java.lang.RuntimeException: Could not obtain configuration from server [http://localhost:8010/auth//realms/BLKRealm/.well-known/uma-configuration].
at org.keycloak.authorization.client.AuthzClient.<init>(AuthzClient.java:82)

at org.keycloak.authorization.client.AuthzClient.<init>(AuthzClient.java:80)
... 4 more

这是产生错误的代码：

import org.keycloak.authorization.client.AuthzClient;
import org.keycloak.representations.AccessTokenResponse;

public class App 

   public static boolean someLibraryMethod() 

   AuthzClient authzClient = AuthzClient.create();

   // send the authorization request to the server in order to
   // obtain an access token granted to the user
   AccessTokenResponse response = authzClient.obtainAccessToken("*****", "*****");

   return true;
   
 public static void main(String[] args)
 
   someLibraryMethod();
 

我理解此错误，但是我不明白为什么我收到此错误，领域已启用UMA，我的客户端已正确配置。有人可以帮助我吗？

答案

使用了错误的UMA发现端点。它是uma 2配置，而不是uma配置（对于某些较旧的Keycloak版本有效）：

http://$host:$port/auth/realms/$realm/.well-known/uma2-configuration
