FB.api dont get email
<p>Im starting usi FB.api to make access to my website with facebook account.</p>

<p>I use, by example this code, token directly from facebook developers:</p>

<pre><code>  window.fbAsyncInit = function() {
        FB.init({
            appId      : '00000000',
            xfbml      : true,
            cookie     : true,
            version    : 'v2.5'
        }); 

        FB.getLoginStatus(function(response) {
            statusChangeCallback(response);
        });
  };

  function statusChangeCallback(response) {
    console.log(response);
    if (response.status === 'connected') {
      testAPI();
    } else if (response.status === 'not_authorized') {
      document.getElementById('status').innerHTML = 'Please log ' +
        'into this app.';
    } else {
      document.getElementById('status').innerHTML = 'Please log ' +
        'into your Facebook.';
    }
  }

  function checkLoginState() {
    FB.getLoginStatus(function(response) {
      statusChangeCallback(response);
    });
  }

  function testAPI() {
    FB.api('/me?fields=last_name,gender,first_name,email', function(response) {
      console.log('Accesso effettuato: ' + response.first_name);
      document.getElementById('status').innerHTML =
        'Grazie per essere entrata, ' + response.last_name + response.email +
        "&lt;img src='" + "https://graph.facebook.com/" + response.id + "/picture?type=large' alt='' /&gt;";
        console.log(JSON.stringify(response));
    });

  }
</code></pre>

<p>The problem is that no fields email is showen! Where is the problem?!
I also check my facebook account to make email visible for other apps/web but nothing change!
Is it a wrong code?!</p>
