FB API GRAPH: why I can't catch the user email?

Question

I'm trying to retreive the email of a user logging into my web app; here's my code:

  FB.api('/me', function(response) {
    console.log(response.name + ', ' + response.email);
  });

the user name is correct, but email results as

undefined

Where am I going wrong?

I don't know how to ask the authorization to get information, as soon as the log in my app — Lorenzo Tosone, Feb 27 '19 at 11:01

_“Where am I going wrong?”_ - you neglected to ask for the fields you want returned, so that you only get the few default ones (id and name, for the user endpoint.) — 04FS, Feb 27 '19 at 11:09
oh, i missed that you don´t even ask for the email. updated my answer. — andyrandy, Feb 27 '19 at 11:19

Ask for the email permission in the login process:

FB.login((response) => {
  // handle the response
}, {scope: 'email'});

Also, you need to ask for the fields you want to get:

FB.api('/me', {fields: 'name,email'}, (response) => {
    console.log(response.name + ', ' + response.email);
});

Make sure the user even has an Email, it´s not required. And make sure you actually get asked for the email permission in the login popup.

Side Note: I would just use console.log(response), so you can see the whole object instead of some undefined values.

Now it works: the problem was that I didn't ask for the fields — Lorenzo Tosone, Feb 27 '19 at 11:27
