ionic3+firebase+angularfire2 facebook 电子邮件为空，每个电子邮件地址有多个帐户

Question

在我的 firebase 仪表板中，我为一个电子邮件选项设置了多个帐户。
firebase dashboard

Angularfire2的配置是标准的所以我没有打app.modules.ts的代码

home.ts

facebookir(){
let goPagePrehome:boolean = false;
let userDB:any;
firebase.auth().signInWithPopup(new firebase.auth.FacebookAuthProvider())
  .then(res => {
    console.log(res);
    console.info(JSON.stringify(res));
    this.userService.getUsers()
    .forEach((users) => {
      users.forEach((user) =>{
            if(user['user_email'] == res.additionalUserInfo.profile.email){
              // console.log('res.additionalUserInfo.profile.email');
              // console.log(user);
              userDB = user;
              goPagePrehome= true;
            }
      });
      if(goPagePrehome){
        this.goNextPagePrehome(userDB);
      }else{
        this.singup();
      }
    });
  }); }

在前面的代码中，用户的电子邮件是在我们的数据库中创建和验证的。并发送到记录“this.singup();”或者到家“this.goNextPagePrehome (userDB);”

sign.ts

this.afAuth.authState.subscribe( user => {
    console.log('find user facebook 2');
    console.log(user);
    if (user){
      if(user.providerData["0"].providerId == "facebook.com"){
        if(this.userData['picture'] == '' || this.userData['picture'] ==  undefined || this.userData['picture']== null){ 
          console.info('find user facebook 2 - si');
          this.userData['name']=this.userData['username']= user.providerData["0"].displayName;
          this.userData['email']=  user.providerData["0"].email;
          this.userData['picture']=  user.providerData["0"].photoURL;
          console.log(this.userData);
        }
      }
      //this.envioCorreoFacebook();
    } else {
      console.info('find user facebook 2 - no');
    }
  });

如您在两个文件中所见，我正在验证邮件中提供商提供的数据为“providerData [”0“]”和“res.additionalUserInfo.profile.email”。
Firebase 响应是：
firebase images

我需要你的帮助来解决一些 facebook 帐户与 firebase 一起工作的问题。？

Answer 1

我又收到邮件了；虽然默认情况下它应该将它带到所有 facebook 帐户。

var provider = new firebase.auth.FacebookAuthProvider();
    provider.addScope('email');
    firebase.auth().signInWithPopup(provider)
      .then(res => {...});
