使用 Facebook 登录集成 (Firebase 3.0) 的 Firebase Auth 用户的空电子邮件字段 [英] Empty email field of Firebase Auth User using Facebook Login Integration (Firebase 3.0)
问题描述
我已成功部署了来自 https://firebase.google.com 的教程代码/docs/auth/android/facebook-login 用于将 Firebase 身份验证登录与 Facebook 集成.在 Firebase 身份验证控制台中成功创建的用户.
I have successfully deployed tutorial code from https://firebase.google.com/docs/auth/android/facebook-login for integrating Firebase Auth logins with Facebook. The users successfully created in Firebase Auth console.
但是，我注意到用户对象中的电子邮件字段为空 (—).奇怪的是，我使用获取的令牌使用 GraphRequest 直接从提供程序结果对象中成功检索了电子邮件信息.
However, I noticed that the Email field in the user object is empty (—). Strangely, I successfully retrieved the email information directly from provider result objects using GraphRequest using the acquired token.
根据我阅读的文档(https://firebase.google.com/docs/reference/android/com/google/firebase/auth/FirebaseUser.html#getEmail())，电子邮件字段应由登录提供商填充.
Based on the documentation I read (https://firebase.google.com/docs/reference/android/com/google/firebase/auth/FirebaseUser.html#getEmail()), the email field should be populated from login providers.
一些额外的奇怪行为:
- 登录成功后，onAuthStateChanged 被调用两次.这firebaseAuth.getCurrentUser().getProviderId() 的值是 Firebase两次
- 我尝试从 FirebaseUser 对象 user.getProviderData() 中列出提供者.我有两个提供商:firebase 和 facebook.com
- 当我尝试使用 FirebaseUser.updateEmail(event.getEmail()) 更新电子邮件时，出现以下错误:发生内部错误.[ EMAIL_EXISTS ]
有什么我想念的吗?我做错了什么?
Is there something I miss or did I do something wrong?
这是我的代码:

// User is signed in
Util.logassert("Auth Provider = " + firebaseAuth.getCurrentUser().getProviderId()); // this is called twice, values of Provider = Firebase
Util.logassert("total provider = " + user.getProviderData().size()); // output = 2. "Firebase" and "facebook.com"
for (int i = 0; i < user.getProviderData().size(); i++) {
UserInfo info = user.getProviderData().get(i);
Util.logassert(info.getProviderId() + ", email = " + info.getEmail()); // both empty
Util.logassert("current provider = " + info.getProviderId() + " - " + info);
}
} else {
Util.logassert("onAuthStateChanged user logged out");
}
// ...
}
};
mAuth.addAuthStateListener(mAuthListener);
// Firebase Facebook TapAuth

mCallbackManager = CallbackManager.Factory.create();

});
Bundle parameters = new Bundle();

Toast.makeText(LoginActivity.this, "Authentication failed :(",
Toast.LENGTH_SHORT).show();

}
@Override

推荐答案
在此处阅读 firebase-talk google group 中的帖子后 https://groups.google.com/forum/#!topic/firebase-talk/gPGNq-IkTLo，我找到了答案.发生此问题是因为我在 Firebase 身份验证登录方法中使用了允许使用相同的电子邮件地址创建多个帐户".
after reading post in firebase-talk google group here https://groups.google.com/forum/#!topic/firebase-talk/gPGNq-IkTLo, I found out the answer. The issue was happened because I'm using "Allow creation of multiple accounts with the same email address" in Firebase Auth sign-in method.
所以我将选项更改为:防止使用相同的电子邮件地址创建多个帐户"现在是否可以正常工作.就这么简单.确实，我需要更多的逻辑来合并具有相同电子邮件地址的帐户，但没关系.
So I change the option into: "Prevent creation of multiple accounts with the same email address" can it's working properly now. It's simple as that. It's true I need more logic to merge accounts having the same email address, but it's okay.
也许其他人也有同样的问题，也可以试试这个，希望它也能解决.
Maybe everyone else having the same issue, can also try this, and hopefully it's solved as well.
