使用电子邮件和密码的 Google Firebase 身份验证不起作用 [英] Google Firebase Authentication with email and password does not work

问题描述

我安装了 Google 的 Firebase 新 SDK，我正在尝试使用身份验证 SDK 创建一个新用户.但是，我完全按照文档说的做了，但它不起作用.有什么意见或建议吗?

I installed the new SDK of Firebase by Google and I am trying to create a new user using the Authentication SDK. However, I did exactly what the documentation says, but it does not work. Any comments or suggestions?

我在 RegisterUserViewController.h 中有身份验证代码

I have the code for Authentication in RegisterUserViewController.h

在 AppDelegate.h 中，我还在 application:didFinishLaunchingWithOptions; 中添加了 [FIRApp configure];

In AppDelegate.h I also added the [FIRApp configure] in application:didFinishLaunchingWithOptions;

这是 RegisterUserViewController.h 的代码:

Here is the code for RegisterUserViewController.h:

#import "RegisterUserViewController.h"
@import FirebaseAuth;
@import Firebase;
@import FirebaseMessaging;
@interface RegisterUserViewController ()

@end

@implementation RegisterUserViewController

- (void)viewDidLoad {
   [super viewDidLoad];
}

- (void)didReceiveMemoryWarning {
   [super didReceiveMemoryWarning];
   // Dispose of any resources that can be recreated.
}

- (IBAction)createUserButton:(id)sender {

[[FIRAuth auth] createUserWithEmail:self.emailTextField.text password:self.passwordTextField.text completion:^(FIRUser * _Nullable user, NSError * _Nullable error)
{
    if(error == nil)
    {
      NSLog(@"%@", user.email);
      NSLog(@"New user Created!");
      [self performSegueWithIdentifier:@"BackToLogin" sender:nil];
    }
    else
    {
      NSLog(@"%@",error);
    }
}];
}

@end

这是我得到的错误:

Error Domain=FIRAuthErrorDomain Code=17999 发生内部错误，打印并检查错误详细信息以获取更多信息."UserInfo=0x7f98fc4609d0 {NSUnderlyingError=0x7f98fc4cf790操作无法完成.(FIRAuthInternalErrorDomain 错误 3.)", error_name=ERROR_INTERNAL_ERROR, NSLocalizedDescription=发生内部错误，打印并检查错误详情以获取更多信息.>
