问Facebook JS API无法注销

EN

Refused to display 'https://www.facebook.com/home.php' in a frame because it set 'X-Frame-  Options' to 'DENY'.

// Facebook Basic Example

window.fbAsyncInit = function() {
  FB.init({
    appId      : '579651098766258',
    status     : true, // check login status
    cookie     : true, // enable cookies to allow the server to access the session
    xfbml      : true  // parse XFBML
  });

  FB.Event.subscribe('auth.authResponseChange', function(response) {
    if (response.status === 'connected') {
      testAPI();
    } else if (response.status === 'not_authorized') {
      FB.login();
    } else {
      FB.login();
    }
  });
};

(function(d){
 var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
 if (d.getElementById(id)) {return;}
 js = d.createElement('script'); js.id = id; js.async = true;
 js.src = "//connect.facebook.net/en_US/all.js";
 ref.parentNode.insertBefore(js, ref);
}(document));



function testAPI() {
  FB.api('/me', function(res) {
    console.log(res);
    setTimeout(function(){
      FB.logout(); // <-- ERROR
    }, 2000);
  });
}
