身份验证失败FireBase Android

我正在使用Firebase身份验证中的

createAccount（）

方法，并附加了两个侦听器：

addOnSuccessListener

和

addOnFailureListener

当我创建一个帐户，同时失去internet连接时，该帐户被成功创建（我可以在Firebase控制台中看到），而

onFailure

侦听器被调用

另外，当我创建此帐户时，我正在Firestore中保存一个用户对象，其中包含一个从auth方法异步调用的

任务。问题是，由于之前的故障，该用户从未在Firestore数据库中创建，但仍然拥有身份验证帐户

结果是用户可以登录，但数据库中不存在，因此他的所有字段都为空

我在Firebase auth方法上找不到任何回滚，所以现在我正在登录用户，同时检查数据库中是否存在具有相同电子邮件的用户对象。。。但我认为这不是一个好办法

那么如何处理这种情况呢

编辑：我正在使用的代码

firebaseAPI.createAccount(email, password, userName).addOnSuccessListener(new OnSuccessListener<AuthResult>() {
    @Override
    public void onSuccess(AuthResult authResult) {
        System.out.println("onSuccess: the firebase user is not null.");
        final FirebaseUser currentUser = authResult.getUser();
        if (currentUser != null) {
            // Send an email to verify the new account created
            currentUser.sendEmailVerification()
                    .addOnSuccessListener(new OnSuccessListener<Void>() {
                        @Override
                        public void onSuccess(Void aVoid) {
                            System.out.println("onSuccess: email verification has been sent.");
                        }
                    })
                    .addOnFailureListener(new OnFailureListener() {
                        @Override
                        public void onFailure(@NonNull Exception e) {
                            System.out.println("onFailure: failed to send the emailVerification.");
                            System.out.println("onFailure: " + e.getMessage());
                        }
                    });

            System.out.println("onComplete: registering the username.");

            // Update the display name of the firebaseUser object
            final UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder().setDisplayName(userName).build();

            currentUser.updateProfile(profileUpdates).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    System.out.println("onFailure: " + e.getMessage());
                    System.out.println("onFailure: failed to update the user display name.");
                }
            }).addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    System.out.println("onSuccess: display name updated.");
                    System.out.println("onSuccess: writing batch.");
                    String uid = currentUser.getUid();
                    // Fields to register in Firestore Database.
                    final User userToRegister = new User(uid, userName, email, birthDate, lastName, firstName);
                    // Register the Username in Firestore Database & the user as the same time to rollback everything if something happens.
                    firebaseAPI.createUser(userToRegister, uid).addOnSuccessListener(new OnSuccessListener<Void>() {
                        @Override

                            onSignUpSuccess(userToRegister);
                        }

如果您的失败监听器被触发，那么您应该记录它提供的异常，以找出哪里出了问题。请编辑该问题，以包含其错误消息以及您正在使用的代码。问题不是错误，我故意在适当的时间关闭了internet连接，以模拟任何用户可能发生的错误。问题是发生这种情况时如何处理。（我还感到惊讶的是，OnSuccess和OnFailure都是为同一个任务调用的）

I/System.out: onFailure: A network error (such as timeout, interrupted connection or unreachable host) has occurred.
