-

i tring facebook friend list getting response null. using javascript sdk. addition in summary getting friend's number. not getting there data.

here code:-

fb.init({     appid      : '{app-id}',     cookie     : true,  // enable cookies allow server access      xfbml      : true,  // parse social plugins on page     version    : 'v1.0' // use version 2.2 }); function testapi() {     fb.login(function(response){         fb.api("/me/friends", function (response) {              console.log(response);         });     },{scope: 'user_friends'}); //  fb.api('/me/feed', 'post', {message: 'hello, world!'}, function(){         //  console.log(response); //  }); }  <fb:login-button scope="public_profile,user_friends" onlogin="checkloginstate();" data-auto-logout-link="true"></fb:login-button>

     fb.login(function(response) {        if (response.authresponse) {             fb.api('/me/friends', {fields: 'xxxxx'}, function(response) {                console.log(response);             });         } else         {             console.log('authorization failed.');         }      },{scope: 'friends'});
