ios - 火力地堡 : How to get email from sign in with apple on real device?

Question

我正在用苹果实现登录，这是我按下苹果按钮的代码

  onAppleButtonPress = async () => {
// performs login request
const appleAuthRequestResponse = await appleAuth.performRequest({
  requestedOperation: AppleAuthRequestOperation.LOGIN,
  requestedScopes: [
    AppleAuthRequestScope.EMAIL,
    AppleAuthRequestScope.FULL_NAME,
  ],
});

// Ensure Apple returned a user identityToken
if (!appleAuthRequestResponse.identityToken) {
  console.log('no token');
  throw 'Apple Sign-In failed - no identify token returned';
}

// Create a Firebase credential from the response
const {identityToken, nonce} = appleAuthRequestResponse;
const appleCredential = firebaseAuth.AppleAuthProvider.credential(
  identityToken,
  nonce,
);


//I WANT TO GET THE EMAIL HERE TO USE CHECK IT FROM FIREBASE IF EMAIL ALREADY EXISTS BY THIS CODE

firebaseAuth()
        .fetchSignInMethodsForEmail(appleAuthRequestResponse.email)
        .then(providers => {

});

}

它在模拟器上工作，但在真实设备上电子邮件为空。谁能帮忙？

Answer 1

Apple 仅在第一次登录时返回全名和电子邮件，在成功登录时它将返回 null，因此您需要保存这些数据。

要再次接收这些信息，请转到您的设备设置； 设置 > Apple ID、iCloud、iTunes 和 App Store > 密码和安全性 > 使用您的 Apple ID 的应用，点击您的应用，然后点击停止使用 Apple ID。您现在可以再次登录，您将收到全名和“电子邮件”。
