所以我必须通过单击进入按钮来请求扩展权限，但是登录后需要刷新页面才能显示应用程序。这是我的代码：

<?php
require 'facebook.php';
$facebook = new Facebook(array(
  'appId'  => '< THE APPID >',
  'secret' => '< THE SECRET >',
  'cookie' => true,
));
$user = $facebook->getUser();

if ($user) {
  try {
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}
?>
<body>
<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {

    FB.init({
      appId      : '< THE APPID >',
      status     : true,
      cookie     : true,
      xfbml      : true
    });

    // Additional initialization code such as adding Event Listeners goes here
    $('#btn-enter').click(function(){
        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 login() {
        FB.login(function(response) {
            if (response.authResponse) {        
                // connected
            } else {
                // cancelled
            }
        //});
        }, {scope: 'read_friendlists,friends_photos,publish_stream'});
    }
</script>
<?php if ($user): ?>
    <!--Here is my APP-->
<?php else: ?>
<a id="btn-enter">Enter</a>
<?php endif ?>

有一个更好的方法吗 ？对我有用的是：

function login() {
    FB.login(function(response) {
        if (response.authResponse) {
            top.location.href='https://the_app_url';            
        } else {
        }
    //});
    }, {scope: 'read_friendlists,friends_photos,publish_stream'});
}

但这会导致整个页面刷新并且本身并不“优雅”......

用户认证后，您可以通过 Javascript SDK 调用图形 API 并向/me.

响应将包含一个带有用户信息的对象。

就是这样：

if (response.authResponse) {
      FB.api('/me', function(response) {
        alert(response.name);
   });  
}

在Facebook 开发者网站上阅读更多关于它的信息。

 require_once("facebook.php");

            }                     
        }

} // end facebook session 
?>

在上面的代码中，在 facebook 用户身份验证后，他们的朋友信息被访问并插入到数据库中。我认为这可能对您有所帮助。这段代码也清除了用facebook登录后刷新页面的问题
