Keycloak API createUser Java

Question

我使用的示例 Java 代码：

public static AjaxResponse createUser(User newUser) {

    Keycloak keycloak = Keycloak.getInstance(
            SERVER_URL,
            REALM,
            USERNAME,
            PASSWORD,
            CLIENT_ID);

    // Get Realm
    RealmResource realmResource = keycloak.realm(REALM);
    UsersResource userResource = realmResource.users();

    // Create User Representation
    UserRepresentation user = getUserRepresentation(newUser);

    // Create user (requires manage-users role)
    try {
        System.out.println("Username: {}", userResource.get("USER-ID-HERE").toRepresentation().getUsername());            
        System.out.println("Count: " + userResource.count());
        Response response = userResource.create(user);
        System.out.println("Response: " + response.getStatusInfo());
        System.out.println("Response: " + response.getStatus());
        System.out.println("Response: " + response.getMetadata());

    } catch (Exception e) {
        System.out.println(ExceptionUtils.getStackTrace(e));
        return new AjaxResponse("Fail", false);
    }

    return new AjaxResponse("Successful User Creation", true);
}

private static UserRepresentation getUserRepresentation(User newUser) {

    UserRepresentation user = new UserRepresentation();
    user.setEnabled(true);
    user.setUsername(newUser.getUsername());
    user.setFirstName(newUser.getFirstName());
    user.setLastName(newUser.getLastName());
    user.setEmail(newUser.getEmail());

    CredentialRepresentation credentialRepresentation = new CredentialRepresentation();
    credentialRepresentation.setTemporary(true);
    credentialRepresentation.setType(CredentialRepresentation.PASSWORD);
    credentialRepresentation.setValue(newUser.getUsername());
    user.setCredentials(Collections.singletonList(credentialRepresentation));

}

运行代码时得到的响应：

Username: USERNAME Correctly Identified here
Count: 98
Response: Conflict
Response: 409
Response: [Connection=keep-alive,Content-Length=46,Content-Type=application/json,Date=Tue, 03 Jul 2018 15:27:58 GMT,Server=WildFly/10,X-Powered-By=Undertow/1]`

一些想法： 我添加了计数，以便确定整个连接是否有效。似乎返回的计数是正确的。因此，我成功连接到 keycloak，但是当我尝试创建用户时出现其他问题。

我的 pom.xml 中的依赖项

    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-servlet-filter-adapter</artifactId>

据我了解，这些依赖项也是相关的：

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>${jackson-version}</version>

        <artifactId>jackson-annotations</artifactId>
        <version>${jackson-version}</version>
    </dependency>

其他信息：

我使用的 Keycloak 版本：3.2.0

Keycloak API 可以在这里找到

可以在此处找到有关 HTTP 409 代码的更多信息

我将不胜感激任何帮助或任何指导。注意 凭据和所有变量已被检查一次、两次、三次和 10 次。我一直在寻找一个完整的工作示例。但大多数未能指定所需的依赖项，因此我的代码失败。

注意：我也在使用 Tomcat-8，因为我正在深入研究这个问题。我看到Tomcat8可能有一些特殊的配置。请注意，我的网络应用程序的身份验证登录注销已经按预期工作。

Answer 1

我终于让它工作了。这是解决方案以供将来参考。

UserRepresentation userRepresentation = new UserRepresentation();
userRepresentation.setUsername("randomUser");
Response response = usersResource.create(userRepresentation);
logger.info("Response |  Status: {} | Status Info: {}", response.getStatus(), response.getStatusInfo());
String userId = response.getLocation().getPath().replaceAll(".*/([^/]+)$", "$1");
UserResource userResource = usersResource.get(userId);

然后我用更多信息更新 userResource。
