在 Java 中创建 keycloak 角色时出现错误 400 错误请求

Question

I try to create a Keycloak role from my Java program. I am able to create user so it's not a problem of connection to my Keycloak server but the create function for the role always give me an error 400 bad request. What is the solution to create a role from Java?

Keycloak kc = KeycloakBuilder.builder()
            .serverUrl("http://localhost:8080/auth")
            .realm("master")
            .grantType(OAuth2Constants.PASSWORD)
            .username("***")
            .password("***")
            .clientId("admin-cli")
            .resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
            .build();

RoleRepresentation roleRepresentation = new RoleRepresentation();
roleRepresentation.setName(nomRole);
roleRepresentation.setClientRole(true);
kc.realm("master").roles().create(roleRepresentation);

error : Exception in thread "main" javax.ws.rs.BadRequestException: HTTP 400 Bad Request at org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.handleErrorStatus(ClientInvocation.java:215) at org.jboss.resteasy.client.jaxrs.internal.proxy.extractors.DefaultEntityExtractorFactory$3.extractEntity(DefaultEntityExtractorFactory.java:50) at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientInvoker.invokeSync(ClientInvoker.java:150) at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientInvoker.invoke(ClientInvoker.java:112) at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientProxy.invoke(ClientProxy.java:76) at com.sun.proxy.$Proxy25.create(Unknown Source) at Main.CreateKeycloakRole(Main.java:37) at Main.main(Main.java:96)

Answer 1

One of the possible cause is nomRole is null.

I can create a role using your code with Keycloak client 4.8.3 and Keycloak server 4.8.3.

Answer 2

I have tried with the Keycloak 4.8.3 version and now it is working as expected ! I think my version was too old to handle role creation ! For me the solution was just to take a newer version ! Thanks all for your help !

Answer 3

我升级到最新的 jboss/keycloak 图像，同样的代码对我有用

Answer 4

The same problem occurred to me when Consent Required was set to ON for a client. If I set it as OFF it works, I am looking into an issue.

Answer 5

您应该将客户端访问类型设置为“公共”（不仅），这很重要
