FIrebase Java/Android createUser失败

Question

我正在尝试编写一个关于Firebase用户创建和身份验证例程的简单测试，以便测试我的Firebase安全设置。代码运行平稳，但没有调用回调，在Firebase端没有创建任何用户。

以下输出的打印语句如下：

Begin process
Start Create User
Creating User
End Creating User
End process

Process finished with exit code 0

尽管我只是在Mac上作为java应用程序运行我的测试，但是该代码使用Firebase -client-Androd-2.2.3.jar文件作为Firebase类。稍后，这将进入一个Android应用程序，但我希望现在能够在我的IDE中运行它。来自经验丰富的Firebase程序员的任何见解都非常感谢。

public class FireRulesTest {


static String firebase_baseUrl = "https://<myfirebase>.firebaseio.com/";

public static void main(String[] args)
        throws FirebaseException {

    System.out.println("Begin process");

    FireRulesTest tester = new FireRulesTest();
    tester.createUser();

    System.out.println("End process");
}

private void createUser()
        throws FirebaseException {

    try {
        System.out.println("Start Create User");

        final String mEmail = "me@email.com";
        final String mPassword = "password";

        final Firebase ref = new Firebase(firebase_baseUrl);
        System.out.println("Creating User");

        ref.createUser(mEmail, mPassword,
                new Firebase.ValueResultHandler<Map<String, Object>>() {

                    @Override
                    public void onSuccess(Map<String, Object> result) {
                        System.out.println("Successfully created user account with uid: " + result.get("uid"));
                        ref.authWithPassword(mEmail, mPassword, new Firebase.AuthResultHandler() {

                                authMap.put("password", mPassword);

                                Firebase currentUserRef = new Firebase(firebase_baseUrl + "movo/users/" + authData.getUid());
                                authMap.put("currentUser", currentUserRef);

                                System.out.println("User ID: " + authData.getUid() +
                                        ", Provider: " + authData.getProvider() +
                                        ", Expires:" + authData.getExpires());


                                System.out.println("Authentication complete");
                            }

                            @Override
                            public void onAuthenticationError(FirebaseError firebaseError) {
                                System.out.println("Authentication Error authenticating newly created user. This could be an issue. ");
                                System.out.println(firebaseError.getMessage());
                            }

                        });

                        }

                        @Override
                        public void onError(FirebaseError firebaseError) {
                        System.out.println("On Error authenticating newly created user. This could be an issue. ");
                            System.out.println(firebaseError.getMessage());
                        }
            });

            System.out.println("End Creating User");

        } catch (Exception fbe) {
            System.out.println("Exception: " + fbe.getMessage());
            fbe.printStackTrace();
        }

    }

}

您需要在程序的末尾添加一个Thread.sleep。可能在Firebase有机会向服务器发送任何内容之前，程序就会退出。

更合适的解决方案是在应用程序中引入实际的生命周期管理，例如等待createUser调用完成。但是，考虑到您将把这个迁移到Android (它处理的应用程序生命周期无论如何完全不同)，这可能是不值得的。
