我记录了这个方法在登录后正确地收到我的应用程序：
private void getUserDataFromProvider（FirebaseUser firebaseUser）{
user = new User（
firebaseUser.getUid（），
firebaseUser.getDisplayName（），
firebaseUser.getEmail（），
firebaseUser.getPhotoUrl（）
）;
Log.i（FIREBASE_ID，user.getFirebaseId（））;
列表<？扩展UserInfo>提供商= firebaseUser.getProviderData（）;
//哪个类型的用户，如果这个secondelement来到
String provider = providers.get（1）.getProviderId（）;
if（provider.equals（facebook.com））{
user.setProvider（FACEBOOK_PROVIDER）;
} else if（provider.equals（password））{
user.setProvider（FLOCKIN_PROVIDER）;
}
}
任何想法？非常感谢
解决方案
从firebase获取facebook accessToken非常简单。我正在使用firebase认证用户界面。通过Facebook认证后，您将从firebase用户对象（如显示名称，电子邮件，提供商详细信息）获取基本信息。但如果你想要更多的信息，如性别，生日facebook Graph API是解决方案。一旦用户通过Facebook进行身份验证，您可以获得这样的访问令牌。
AccessToken.getCurrentAccessToken（）
但有时它会给你NULL值，而不是有效的访问令牌。确保您已经在此之前初始化了Facebook SDK。
public class MyApplication extends Application {
@Override
public void onCreate（）{
super.onCreate（）;
FacebookSdk.sdkInitialize（this）;
}
}
初始化后使用graphAPI
if（AccessToken.getCurrentAccessToken（）！= null）{
System.out.println（AccessToken.getCurrentAccessToken（）。getToken （））;
GraphRequest request = GraphRequest.newMeRequest（
AccessToken.getCurrentAccessToken（），
new GraphRequest.GraphJSONObjectCallback（）{
@Override
public void onCompleted JSONObject对象，GraphResponse响应）{
//应用程序代码
try {
String email = object.getString（email）;
String gender = object.getString（gender ）;
} catch（JSONException e）{
e.printStackTrace（）;
}
}
}）;
Bundle parameters = new Bundle（）;
parameters.putString（fields，id，name，email，gender，birthday）;
request.setParameters（parameters）;
request.executeAsync（）;
}
else
{
System.out.println（访问令牌NULL）;
}

firebaseUser.getEmail(),
firebaseUser.getPhotoUrl()
);
Log.i("FIREBASE_ID",user.getFirebaseId());
List<? extends UserInfo> providers=firebaseUser.getProviderData();
//which type of user,if thesecondelement comes
String provider= providers.get(1).getProviderId();
if(provider.equals("facebook.com")){
user.setProvider(FACEBOOK_PROVIDER);
}else if(provider.equals("password")){
user.setProvider(FLOCKIN_PROVIDER);
}
}
Any Ideas?. Thank you very much
解决方案
To get facebook accessToken from firebase is very simple. I was using firebase auth UI. After authentication with facebook you will get basic information from firebase user object like display name, email,provider details. But if you want more information like gender, birthday facebook Graph API is the solution. Once user authenticated with the facebook you can get access token like this.
AccessToken.getCurrentAccessToken()
But sometimes it will give you NULL value instead of valid access token. Make sure that you have initialized facebook SDK before that.
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
FacebookSdk.sdkInitialize(this);
}
}
After initialization use graphAPI
if(AccessToken.getCurrentAccessToken()!=null) {
System.out.println(AccessToken.getCurrentAccessToken().getToken());
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
// Application code
try {
String email = object.getString("email");
String gender = object.getString("gender");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
else
{
System.out.println("Access Token NULL");
}
Happy Coding :)
