Question

我正在使用WordPress在Facebook上制作应用程序，一切都很好，我在应用程序的首页上，但当我尝试在Mozilla Firefox中访问我的应用程序的另一个页面的链接时显示空白页面，并且谷歌浏览器保留在首页。

有谁知道为什么会这样？有没有人遇到过这种行为？

我的下一个代码是我在WordPress根index.php中使用的，而不是首页index.php，用于在进入应用程序之前请求用户的权限：

<?php
/**
 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 *
 * @package WordPress
 */

/**
 * Tells WordPress to load the WordPress theme and output it.
 *
 * @var bool
 */

session_start();
require 'src/facebook.php';

//  LOGIN
$app_details = array('app_id' => 'secret',
                     'app_secret' => 'secret',
                     'page_link' => '//www.facebook.com/secret/'
                     );
$http = "http:";
if(isset($_SERVER['HTTPS'])) 
    if (!empty($_SERVER['HTTPS'])) $http = "https:";
$facebook = new Facebook(array(
  'appId'  => $app_details['app_id'], 
  'secret' => $app_details['app_secret'],
  'cookie' => true 
));

$the_signed_request = $facebook->getSignedRequest();
if ($the_signed_request == null) {
    header("Location: ".$http.$app_details['page_link']."app/".$app_details['app_id']);
}

if ( !isset($the_signed_request['user_id']) && !isset($the_signed_request['oauth_token']) ){
    $loginUrl = $facebook->getLoginUrl(array('scope'=>'email')); 
   if (!isset($_SESSION['rejects'])) $_SESSION['refuzuri'] = 0;
        else $_SESSION['rejects']++;
    if ($_SESSION['rejects']>4) {
        echo "This app works only if permissions are accepted.<br/>";
        echo "To accept the permissions <a href='".$loginUrl."' target='_top'>click here</a>";
        die();
    } 
    echo( "<script>top.location.href='" . $loginUrl . "';</script>" );
}else{
     try{
        $access_token = $facebook->getAccessToken();
        $user = $facebook->getUser();//userid
         $userinfo = $facebook->api('/me?fields=id,name,email,gender,locale'); //for basic details

    }catch (FacebookApiException $e) {
     $user = null;
     $userinfo = null;         
    }
    $_SESSION['user']= $userinfo;
        define('WP_USE_THEMES', true);

        /** Loads the WordPress Environment and Template */
        require( dirname( __FILE__ ) . '/wp-blog-header.php' );

}
?>

为什么我的Facebook应用程序没有加载页面？
