Firebase 3 - javascript - 登录后获取facebook accessToken

Question

In Firebase 2 I was able to get facebook accessToken from anywhere after login by this way, just using the firebase reference , eg:

firebase.getAuth().facebook.accessToken

Now, how can I get that in version 3 (web)?

Note, I need it outside of the Promise signInWithPopup

Thanks

Answer 1

I just found this on documentation... Why? :(

Since Firebase Authentication no longer persists the access token, your application will have to do so itself, if needed.

Answer 2

Try this:

firebase.auth().signInWithPopup(provider).then(function(result) {

    // This gives you a Facebook Access Token. You can use it to access the Facebook API.
    var token = result.credential.accessToken;
})

Answer 3

The easiest way to get the user access token is to use the FB API itself.

Simply follow this guide on how to include it and then get the token the following way:

FB.getLoginStatus(function(response) {
  if (response.status === 'connected') {
    var accessToken = response.authResponse.accessToken;
  } 
} );

Answer 4

可能的答案是取消链接“auth.currentUser.unlink（provider）”提供程序，并在每次需要获取访问令牌时重新链接“auth.currentUser.linkWithPopup（provider）”。
