如何更新领域中现有的 Keycloak 客户端属性？

Question

我在 keycloak 中为每个客户端添加了一些属性，现在我需要在不删除客户端的情况下将现有客户端属性更新为新值。

List<ClientRepresentation> list = realm.clients().findByClientId(client.getClientId());
ClientResource resource = realm.clients().get(client.getClientId());

ClientRepresentation clientRepresentation = list.get(0);
        //clientRepresentation.getAttributes().put(KeyCloakAttribute.OBJECT_BASED_ACCESS.getLabel(), application.getAttributes().getObjectBasedModel());
clientRepresentation.setName("updated-name");
resource.update(clientRepresentation); <- This line is throwing error

我可以看到客户端资源正在提供更新方法，但是当我使用它时出现 404 错误。

keycloak client resource update docs

我是不是做错了，还是有其他方法可以做到？

Answer 1

根据 API 文档 realm.clients() returns ClientsResource interface. The method findByClientId requests the clientId as parameter but the method get:

@Path(value="{id}")
ClientResource get(@PathParam(value="id")
                                       String id)

请求客户端的 id，而不是客户端 ID。

所以你需要替换：

realm.clients().get(client.getClientId());

和

realm.clients().get(client.getId());
