ionic3+firebase+angularfire2 facebook email null with Multiple accounts per email address - facebook

Question

In my firebase dashboard I have set multiple accounts for one email option.
firebase dashboard
The configuration of Angularfire2 is the standard so I do not hit the code of app.modules.ts
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();
}
});
}); }
In the previous code, the user's email is created and verified in our database. And is sent to the record "this.singup ();" Or to the home "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');
}
});
As you can see in both files I am verifying the mail for the data supplied by the provider as "providerData [" 0 "]" and "res.additionalUserInfo.profile.email".
The firebase response is:
firebase images
I need your help to correct this problem that some facebook accounts work with firebase.?

Answer 1

I got the mail again; although by default it should bring it to all facebook accounts.
var provider = new firebase.auth.FacebookAuthProvider();
provider.addScope('email');
firebase.auth().signInWithPopup(provider)
.then(res => {...});
