Facebook JS SDK's FB.api('/me') method doesn't return the fields I expect in Graph API v2.4+

I'm trying to get some basic information using Facebook api, but so far I only get the user's name and id. As in { name: "Juan Fuentes", id: "123456" }

I need to get mor einformation, like email, first name, last name and birthday

This is my js code

function facebookLogin() {
  FB.login(function(response) {
    var token = response.authResponse.accessToken;
    var uid = response.authResponse.userID;
    if (response.authResponse) {
      FB.api('/me', 'get', { access_token: token }, function(response) {
        console.log(response);
      });

      FB.api('/'+uid, 'get', { access_token: token }, function(response) {
        console.log(response);
      });
    }
  },
  { scope: 'public_profile' }
  );
}

And this is the button that activates it

<a id="fb-login" href="#" onclick="facebookLogin()"></a>

You need to manually specify each field since Graph API v2.4:

• https://developers.facebook.com/docs/apps/changelog#v2_4
• https://developers.facebook.com/docs/javascript/reference/FB.api

Declarative Fields
To try to improve performance on mobile networks, Nodes and Edges in v2.4 requires that you explicitly request the field(s) you need for your GET requests. For example, GET /v2.4/me/feed no longer includes likes and comments by default, but GET /v2.4/me/feed?fields=comments,likes will return the data. For more details see the docs on how to request specific fields.

E.g.

FB.api('/me', 'get', { access_token: token, fields: 'id,name,gender' }, function(response) {
    console.log(response);
});

It's also possible to use this syntax for data from public_profile scope (tested in Graph API v2.9):

FB.api('/me?fields=birthday,link,gender,age_range', function(response) {
   console.log(response);
});

You can test the possible values online in Graph API Explorer, just click "Get Token" button:
