无法在Firebase中使用Google身份验证获取电子邮件 [英] Not getting the email using Google Authentication in Firebase

问题描述

我正在使用Firebase提供的代码进行Google身份验证，以某种方式，身份验证成功，但是电子邮件未正确导入到Firebase.

I am using the code provided by Firebase for Google Authentication and somehow, the authentication was successful but the email was not correctly imported to Firebase.

https://firebase.google.com/docs/auth/ios/谷歌登录

如下面的屏幕截图所示，电子邮件为空白.当我看着调试器时，它显示为nil.
我单击了允许在身份验证期间查看电子邮件"，但我认为仍有一些设置未正确完成.有人可以帮我看看吗?我有兴趣使用电子邮件为每个用户创建用户名.

As you can see in the screenshot below, the email is blank. When I looked at the debugger, it is showing nil.
I clicked allow viewing email during authentication but I think there are still some settings that was not done correctly. Could someone help me to take a look? I am interested to use the email to create the username for each user.

func signIn(signIn: GIDSignIn!, didSignInForUser user: GIDGoogleUser!, withError error: NSError!) {
    if let error = error {
        print(error.localizedDescription)
        return
    }

    let authentication = user.authentication
    let credential = FIRGoogleAuthProvider.credentialWithIDToken(authentication.idToken,
                                                                 accessToken: authentication.accessToken)
    FIRAuth.auth()?.signInWithCredential(credential) { (user, error) in
        if error != nil {
            print(error?.localizedDescription)
            return
        }

        print("User logged in with Google...")
        self.performSegueWithIdentifier("ToHome", sender: nil)
    }
}

推荐答案

该电子邮件未在Firebase控制台上显示，因为您允许用户使用同一封电子邮件创建多个帐户.如果您导航到 Auth->登录方式，您可以将选项设置为避免使用同一封电子邮件创建多个帐户.完成此操作后，创建用户时电子邮件将开始显示.

The email is not showing on firebase console because you are allowing users to create multiple accounts with the same email. If you navigate to Auth -> Sign-in method you can set the option to Avoid creating multiple accounts with the same e-mail. After doing so the emails will start to appear when creating the user.

在此处不确定，但是如果您仍要创建多个帐户并将用户电子邮件放在应用程序端，我想您在创建用户时需要将电子邮件存储在firebase数据库上.

Not sure here but, if you still want to create multiple accounts and have the user email on the application side I guess that you will need to store the email on firebase database when creating the user.
