java - Keycloak 创建用户角色

Question

我已经将新用户和角色都插入到 keycloak 中。但是我如何连接用户和角色实体，如用户角色

Keycloak kc = KeycloakBuilder.builder()
                .serverUrl("http://localhost:8080/auth")
                .realm("master")
                .username("admin")
                .password("admin")
                .clientId("admin-cli")
                .resteasyClient(
                    new ResteasyClientBuilder()
                        .connectionPoolSize(10).build()
                ).build();
//creating role
RoleRepresentation roleRepresentation = new RoleRepresentation();
        roleRepresentation.setName("latest_role");
        kc.realm("master").roles().create(roleRepresentation);
//creating user
UserRepresentation user = new UserRepresentation();
        user.setUsername("anoop");
        user.setFirstName("anoop");
        user.setLastName("anoop");
        user.setEnabled(true);
        user.setCredentials(Arrays.asList(credential));
        kc.realm("master").users().create(user);

这似乎不是一个微不足道的问题。通常我希望 user.setRealmRoles(roleRepresentation) 中有此功能，例如 this example .但这对我不起作用。

相反，我使用此函数将 roleRepresentation 添加到 user。

RoleRepresentation savedRoleRepresentation = kc.realm("master").roles()
        .get("latest_role").toRepresentation();
kc.realm("master").users().get(userId).roles().realmLevel()
        .add(asList(savedRoleRepresentation));

完整代码:

Keycloak kc = Keycloak.getInstance("http://localhost:8080/auth",
        "master", "admin", "admin", "admin-cli");

RoleRepresentation roleRepresentation = new RoleRepresentation();
roleRepresentation.setName("latest_role");
kc.realm("Test").roles().create(roleRepresentation);

UserRepresentation user = new UserRepresentation();
user.setUsername("test");
user.setFirstName("test");
user.setLastName("test");
user.setEnabled(true);
user.setCredentials(Arrays.asList(credential));

Response response = kc.realm("Test").users().create(user);
String userId = getCreatedId(response);

System.out.println("Testuser created.... verify in keycloak!");

RoleRepresentation savedRoleRepresentation = kc.realm("Test").roles()
        .get("latest_role").toRepresentation();
kc.realm("Test").users().get(userId).roles().realmLevel()
        .add(asList(savedRoleRepresentation));


private String getCreatedId(Response response) {
    URI location = response.getLocation();
    if (!response.getStatusInfo().equals(Response.Status.CREATED)) {
        Response.StatusType statusInfo = response.getStatusInfo();
        throw new WebApplicationException("Create method returned status " +
                statusInfo.getReasonPhrase() + " (Code: " + statusInfo.getStatusCode() + "); expected status: Created (201)", response);
    }
    if (location == null) {
        return null;
    }
    String path = location.getPath();
    return path.substring(path.lastIndexOf('/') + 1);
}

编辑:

似乎没有为用户保存凭据。要强制 keycloak 保存它们，您必须使用以下方法重置密码:

UserResource userResource = kc.realm("Test").users().get(userId);
userResource.resetPassword(credential);
