键盘锁- Uma配置

Question

当尝试使用keycloak java api我得到这个错误：

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.create(AuthzClient.java:56)
at org.keycloak.authorization.client.AuthzClient.create(AuthzClient.java:49)
at KeyCloackApiCaller.Caller.App.someLibraryMethod(App.java:14)
at KeyCloackApiCaller.Caller.App.main(App.java:26)
Caused by: org.keycloak.authorization.client.util.HttpResponseException: Unexpected response from server: 404 / Not Found
at org.keycloak.authorization.client.util.HttpMethod.execute(HttpMethod.java:92)
at org.keycloak.authorization.client.util.HttpMethodResponse$2.execute(HttpMethodResponse.java:48)
at org.keycloak.authorization.client.AuthzClient.<init>(AuthzClient.java:80)
... 4 more

这是生成错误的代码：

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();
 }
}

我理解这个错误，但我不明白为什么我收到这个错误，领域已启用UMA，我的客户端已正确配置。有人能帮我吗？

Answer 1

产生了这个问题，因为我使用了过时的api。

要解决这个问题，如果您使用的是maven，请设置正确的版本：

<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-authz-client</artifactId>
    <version>8.0.1</version>
</dependency>

谢谢你的帮助。

您使用了错误的UMA发现endpoint。它是uma2配置，而不是uma-配置（它对一些较旧的Keycloak版本有效）：

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