Question

我正在尝试使用facebook登录并回显用户的/我/图表细节。我根据facebook的开发者页面编写了以下代码，但是出了问题，页面https://qonnect.co/fbcon.php不会加载！

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Qonnect | Your online ID on the web</title>
<meta content="online identity, social network, contact details, share, personal profile">
<?php require_once("facebook.php"); ?>
</head>

<body>
  <p>chekc access token at bottom</p>
<?php 

   $app_id = "353349231445***";
   $app_secret = "1299cd46fd******";
   $my_url = "https://www.qonnect.co";

   session_start();

   $code = $_REQUEST["code"];

   if(empty(code))
   {
    $_SESSION['state']= md5(uniqid(rand(), TRUE));
      $dialog_url = "https://www.facebook.com/dialog/oauth?client_id=" 
       . $app_id . "&redirect_uri=" . urlencode($my_url) . "&state="
       . $_SESSION['state'] . "&scope=user_birthday,read_stream";

     echo("<script> top.location.href='" . $dialog_url . "'</script>");
   }

      //rechecking of sessions state variable for CSRF attack !
      if($_SESSION['state'] && ($_SESSION['state'] === $_REQUEST['state'])) {
        $token_url = "https://graph.facebook.com/oauth/access_token?"."client_id=".$app_id.
        "&redirect_uri=".urlencode($my_url)."&client_secret=".$app_secret."&code=".$code; //code exchanged for access token.
        $response = file_get_contents($token_url);
        $params = null;
        parse_str($response, $params);

        $graph_url = "https://graph.facebook.com/me?access_token=". $params['access_token'];
        $user = json_decode(file_get_contents($graph_url));
        echo("Hello", $user->name);
     }
   else {
     echo("The state does not match. You may be a victim of CSRF.");
   }
?>

</body>
</html>

如果我是对的，500内部服务器错误可能是一个问题造成的由
A malformed php cgi script
An invalid directive in an .htaccess or other config file
Limitation imposed by file system and server software 
Error/Missing php.ini
在大多数情况下，它是无效的.htaccess指令

你能检查

吗？

1）.htaccess

2）让我知道整个PHP代码的抓取

>       try{
>     
>     } catch(Exception $o){
>           echo $o;
>       }

3.可以设置

set_time_limit ( int seconds)
