Question

使用Firebase身份验证成功创建新用户帐户后，我尝试在Firebase数据库中创建第二个请求以创建其个人资料（姓名，电子邮件和电话），但如果第二个请求失败，我将有一个用户没有个人资料，这种情况不可能，因为他登录时无法编辑他的个人资料，所以目前我正在Firebase Auth中删除这个最近创建的用户，允许他重试创建，但是它不能解决问题，因为删除请求也可能失败。在Firebase中处理交易的最佳方法是什么，既成功创建了用户及其个人资料，又没有成功创建？

 private void attemptToCreateAccount(final Credentials cred) {
        getCompositeDisposable().add(
                getAuthService().createAccount(cred)
                        .subscribeOn(getSchedulerProvider().io())
                        .observeOn(getSchedulerProvider().ui())
                        .subscribeWith(new DisposableSingleObserver<User>() {
                            @Override
                            public void onSuccess(User user) {
                                 addUserProfileToDatabase(user.getEmail(), user.getUserUid(), cred.getUsername(), cred.getPassword());
                            }

                            @Override
                            public void onError(Throwable e) {
                                getView().showMessage(e.toString());
                            }
                        })
        );
    }

 private void addUserProfileToDatabase(final String email, final String userUid, final String name, final String password) {
        final Profile profile = new Profile("", "", "", email, "", name);
        getCompositeDisposable().add(
                getDatabaseSource().createNewProfileToUser(userUid, profile)
                .subscribeOn(getSchedulerProvider().io())
                .observeOn(getSchedulerProvider().ui())
                .subscribeWith(new DisposableCompletableObserver(){
                    @Override
                    public void onComplete() {
                        getView().saveUserData(userUid, email, name);
                        getView().goToProfilePageActivity();
                    }

                    @Override
                    public void onError(Throwable e) {
                        // TODO RETRY OPERATION OR DELETE THE CURRENT CREATED USER
                        getView().showMessage(e.getLocalizedMessage());
                        deleteUserCreatedWithoutProfile(email, password);
                    }
                })
        );
    }

private void deleteUserCreatedWithoutProfile(String email, String password){
        getCompositeDisposable().add(
                getDatabaseSource().deleteUser(email, password)
                .observeOn(getSchedulerProvider().io())
                .observeOn(getSchedulerProvider().ui())

                    @Override
                    public void onComplete() {
                        Log.e("FIREBASE", "user deleted because profile could not be created successfully");
                    }

                    @Override
                    public void onError(Throwable e) {
                        Log.e("FIREBASE", "Houston We have a problem. User was created without a profile.");
                    }
                })
        );

你不需要FirebaseDatabase就可以存储用户信息firebaseAuth了解你如何做到

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

UserProfileChangeRequest profileUpdates = new UserProfileChangeRequest.Builder()
        .setDisplayName("Jane Q. User")
        .setPhotoUri(Uri.parse("https://example.com/jane-q-user/profile.jpg"))
        .build();

user.updateProfile(profileUpdates)
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "User profile updated.");
                }
            }
        });
