在使用 keycloak-admin-client 创建用户期间出现 403

Question

I am trying to create a new user with java-admin-client. I created a new client in my realm using keycloak UI.

Client:

access type: confidential

roles: view-users, view-realm, view-clients, manage-users (these roles are just added by name in keycloak UI)

Code:

final Keycloak keycloak = KeycloakBuilder.builder()
    .serverUrl("https://{keycloakurl}/auth")
    .realm(realm)
    .grantType(OAuth2Constants.CLIENT_CREDENTIALS)
    .clientId("client")
    .clientSecret("uuidSecret")
    .build();

final UserRepresentation user = new UserRepresentation();
user.setEnabled(true);
user.setUsername("test");
user.setFirstName("test1");
user.setLastName("test2");
user.setEmail("test@test.com");
user.setAttributes(Collections.singletonMap("origin", Arrays.asList("demo")));

final RealmResource realmResource = keycloak.realm(realm);
final UsersResource userResource = realmResource.users();

final Response response = userResource.create(user);

The last line is giving me 403 Forbidden.

Answer 1

I think 403 as you have no role 'manage-users'. Add to your user fro 'realm-management' client, inside your realm.

We created one service-account user, just to query users by uuid. These three files does that, plus properties from application.properties. Update code and try what you wanted

@EnableOAuth2Client
@Configuration
public class KeycloakConfiguration {

//  token-service-uri=https://keycloak.internal/auth/realms/some-realm/protocol/openid-connect/token
//  admin-query.client-id=client
//  admin-query.username=service-account
//  admin-query.password=password
//  admin-query.admin-base-url=https://keycloak.internal/auth/admin/realms/realm

@Value("${token-service-uri}")
private String tokenServiceUri;

@Value("${admin-query.client-id}")
private String clientId;

@Value("${keycloak.credentials.secret}")
private String clientSecret;

@Value("${admin-query.username}")
private String username;

@Value("${admin-query.password}")
private String password;


private final String grantType = "password";


@Bean
public OAuth2ProtectedResourceDetails cryptoKeycloakResourceDetails() {

    ResourceOwnerPasswordResourceDetails details = new ResourceOwnerPasswordResourceDetails();
    details.setAccessTokenUri(tokenServiceUri);
    details.setClientId(clientId);
    details.setClientSecret(clientSecret);
    details.setGrantType(grantType);
    details.setUsername(username);
    details.setPassword(password);

    return details;
}


@Bean
public OAuth2RestTemplate cryptoKeycloakRestTemplate(OAuth2ClientContext clientContext) throws Exception {

    // build template with custom SSL TrustStrategy

    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
            .loadTrustMaterial(null, acceptingTrustStrategy)
            .build();
    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

    CloseableHttpClient httpClient = HttpClients.custom()
            .setSSLSocketFactory(csf)
            .build();

    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(httpClient);

    AuthorizationCodeAccessTokenProvider authCodeAccessTokenProvider = new AuthorizationCodeAccessTokenProvider();
    authCodeAccessTokenProvider.setRequestFactory(requestFactory);

    ImplicitAccessTokenProvider implicitAccessTokenProvider = new ImplicitAccessTokenProvider();
    implicitAccessTokenProvider.setRequestFactory(requestFactory);

    ResourceOwnerPasswordAccessTokenProvider resourceOwnerTokenProvider = new ResourceOwnerPasswordAccessTokenProvider();
    resourceOwnerTokenProvider.setRequestFactory(requestFactory);

    ClientCredentialsAccessTokenProvider clientCredentialsTokenProvider = new ClientCredentialsAccessTokenProvider();

    AccessTokenProvider accessTokenProvider = new AccessTokenProviderChain(
            Arrays.<AccessTokenProvider> asList(authCodeAccessTokenProvider, implicitAccessTokenProvider,
                    resourceOwnerTokenProvider, clientCredentialsTokenProvider));

    AccessTokenRequest request = new DefaultAccessTokenRequest();
    OAuth2RestTemplate template = new OAuth2RestTemplate(cryptoKeycloakResourceDetails(), new DefaultOAuth2ClientContext(request));
    template.setAccessTokenProvider(accessTokenProvider);
    template.setRequestFactory(requestFactory);
    return template;
}
}
