Facebook Login Graph API

Boa tarde!!!

Estou implementando a api para login com facebook em uma aplicação web. Estou com dúvida de como fazer para resgatar as informações do usuário que acessou...

O código que estou usando:

// This is called with the results from from FB.getLoginStatus().

 function statusChangeCallback(response) {
 console.log('statusChangeCallback');
 console.log(response);
 // The response object is returned with a status field that lets the
 // app know the current login status of the person.
 // Full docs on the response object can be found in the documentation
 // for FB.getLoginStatus().
 if (response.status === 'connected') {
 // Logged into your app and Facebook.

 /*testAPI();*/
 } else if (response.status === 'not_authorized') {
 // The person is logged into Facebook, but not your app.
 document.getElementById('status').innerHTML = 'Please log ' +
 'into this app.';
 } else {
 // The person is not logged into Facebook, so we're not sure if
 // they are logged into this app or not.
 document.getElementById('status').innerHTML = 'Por favor, logue ' +
 'com o Facebook.';
 }
 }

 // This function is called when someone finishes with the Login
 // Button. See the onlogin handler attached to it in the sample
 // code below.
 function checkLoginState() {
 FB.getLoginStatus(function(response) {
 statusChangeCallback(response);
 });
 }

 function logout() {
 FB.logout(function(response) {
 window.location.href="index.php";
 });
 }

 window.fbAsyncInit = function() {
 FB.init({
 appId : '',
 cookie : true, // enable cookies to allow the server to access
 // the session
 xfbml : true, // parse social plugins on this page
 version : 'v2.2' // use version 2.2
 });

 // Now that we've initialized the JavaScript SDK, we call
 // FB.getLoginStatus(). This function gets the state of the
 // person visiting this page and can return one of three states to
 // the callback you provide. They can be:
 //
 // 1. Logged into your app ('connected')
 // 2. Logged into Facebook, but not your app ('not_authorized')
 // 3. Not logged into Facebook and can't tell if they are logged into
 // your app or not.
 //
 // These three cases are handled in the callback function.

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

 };

 // Load the SDK asynchronously
 (function(d, s, id) {
 var js, fjs = d.getElementsByTagName(s)[0];
 if (d.getElementById(id)) return;
 js = d.createElement(s); js.id = id;
 js.src = "//connect.facebook.net/pt_BR/sdk.js";
 fjs.parentNode.insertBefore(js, fjs);
 }(document, 'script', 'facebook-jssdk'));

 // Here we run a very simple test of the Graph API after login is
 // successful. See statusChangeCallback() for when this call is made.
 function testAPI() {
 console.log('Welcome! Fetching your information.... ');
 FB.api('/me', function(response) {
 console.log('Successful login for: ' + response.name);
 document.getElementById('status').innerHTML =
 'Thanks for logging in, ' + response.name + '!';
 });
 }

<fb:login-button scope="public_profile,email,user_friends,user_likes" auth_type= "rerequest" onlogin="checkLoginState();"></fb:login-button>

Gostaria de saber como verficar os dados requisitados pelo acesso com o facebook login... Digamos que 10 usuários fizeram login em minha aplicação, como faço para ver os 10 separadamente pelo retorno Json que vem no Graph api explorer? Ou qual a melhor forma de fazer isso? Alguém sabe aí???
