      channelUrl : 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx', // Channel File
      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')

Answer 1

如果朋友们也授权你的应用程序，那么他们只会出现，这一点非常重要。但我的猜测是你忘了在登录时要求user_friends权限。我没有在范围内看到它。

不过，您还应该使用JS SDK的最新代码：https://developers.facebook.com/docs/javascript/quickstart/v2.2

Answer 2

将此代码替换为以前的代码，并从代码中删除旧代码并匹配}

  window.fbAsyncInit = function() {
FB.init({
      appId      : 'XXXXXXXXXXXXX',
      xfbml      : true,
      version    : 'v2.2'
    });
  };
  (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/en_US/sdk.js";
     fjs.parentNode.insertBefore(js, fjs);
   }(document, 'script', 'facebook-jssdk'));
