使用 java 向 keycloak 用户添加客户端角色

Question

我正在使用 Keycloak Admin Client 库尝试创建一个用户，然后向该创建的用户添加一个客户端角色。我在创建用户时没有任何问题，但是当我尝试为该用户分配角色时，我收到错误消息：

javax.servlet.ServletException: java.lang.IllegalStateException: RESTEASY003765: Response is closed.
    org.glassfish.jersey.servlet.WebComponent.serviceImpl(WebComponent.java:487)
    org.glassfish.jersey.servlet.WebComponent.service(WebComponent.java:425)
    org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:383)
    org.glassfish.jersey.servlet.ServletContainer.service(ServletContainer.java:336)

    org.apache.catalina.filters.CorsFilter.handleNonCORS(CorsFilter.java:441)
    org.apache.catalina.filters.CorsFilter.doFilter(CorsFilter.java:169)

这是我的代码出错的地方：

// Get realm
        RealmResource realmResource = keycloak.realm(realm);
        UsersResource userRessource = realmResource.users();

                System.out.println(userId);

        // Get client
        ClientRepresentation app1Client = realmResource.clients()
                .findByClientId("digicor").get(0);

                System.out.println("app1Client.getId: "+app1Client.getId());

                System.out.println("realmResource.clients()) = "+ realmResource.clients().toString());

                System.out.println("realmResource.roles().list() ="+realmResource.roles().list());

                System.out.println("realmResource.roles().list().get(0) ="+realmResource.roles().list().get(0));

                System.out.println(" realmResource.clients().findAll() ="+ realmResource.clients().findAll());

                System.out.println(" realmResource.clients().findAll().get(0).toString ="+ realmResource.clients().findAll().toString());

                System.out.println("realmResource.clients().get(digicor) = "+ realmResource.clients().get("digicor"));

                System.out.println("realmResource.clients().get(digicor).roles() = "+ realmResource.clients().get("digicor").roles());

                System.out.println("realmResource.clients().get(\"digicor\").roles().get(\"development\") = "+ realmResource.clients().get("digicor").roles().get("development").toString());

                RoleRepresentation clientRole = realmResource.clients().get("digicor").roles().get("development").toRepresentation();
      //Breaks on the above line and never reaches this print.           
                System.out.println("Role Representation made");

这是我的 pom.xml:

我正在使用 Maven 构建这个项目，然后运行它作为服务器上的 docker 图像。

非常感谢任何帮助，谢谢。

Answer 1

我通过以下方式将角色分配给用户

String userRole = "development";

List<RoleRepresentation> roleRepresentationList = userResource.roles().realmLevel().listAvailable();

for (RoleRepresentation roleRepresentation : roleRepresentationList)
  {
    if (roleRepresentation.getName().equals(userRole))
      {
        userResource.roles().realmLevel().add(Arrays.asList(roleRepresentation));
        break;
     }
  }

如果您想将客户级别的角色分配给 User ，您可以按如下方式操作

ClientRepresentation clientRep = realmResource.clients().findByClientId("digicor").get(0);
RoleRepresentation clientRoleRep = realmResource.clients().get(clientRep.getId()).roles().get("development").toRepresentation();
userResource.roles().clientLevel(clientRep.getId()).add(Arrays.asList(clientRoleRep));

使用 java 向 keycloak 用户添加客户端角色

Add a client role to a keycloak user using java

java

roles

admin

resteasy

keycloak
