iFrame应用程序..在用户授权应用程序后重定向回页面选项卡

Question

我有很多麻烦让我的Facebook应用程序在用户授权后重定向回页面选项卡。

我的应用程序将生活在多个页面上，因此它不像为重定向粘贴网址那么简单。有没有办法抓取网页的ID并将其放入重定向网址？这里是我的代码...

<?php 
session_start(); 

//facebook application configuration -mahmud 
$fbconfig['appid' ] = "xxx"; 
$fbconfig['secret'] = "xxxxxxxxxxxxx"; 

$fbconfig['baseUrl'] = "http://localhost/foods/"; 
$fbconfig['appBaseUrl'] = ""; //Need page tab url here 


/* 
* If user first time authenticated the application facebook 
* redirects user to baseUrl, so I checked if any code passed 
* then redirect him to the application url 
* -mahmud 
*/ 
if (isset($_GET['code'])){ 
    //header("Location: " . $fbconfig['appBaseUrl']); 
    // exit; 
} 
//~~ 

// 
if (isset($_GET['request_ids'])){ 
    //user comes from invitation 
    //track them if you need 
} 

$user   = null; //facebook user uid 
try{ 
    include_once "facebook.php"; 
} 
catch(Exception $o){ 
    echo '<pre>'; 
    print_r($o); 
    echo '</pre>'; 
} 
// Create our Application instance. 
$facebook = new Facebook(array(
    'appId' => $fbconfig['appid'], 
    'secret' => $fbconfig['secret'], 
    'cookie' => true, 
)); 

//Facebook Authentication part 
$user  = $facebook->getUser(); 
// We may or may not have this data based 
// on whether the user is logged in. 
// If we have a $user id here, it means we know 
// the user is logged into 
// Facebook, but we don’t know if the access token is valid. An access 
// token is invalid if the user logged out of Facebook. 

$loginUrl = $facebook->getLoginUrl(); 

if ($user) { 
    try { 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api('/me'); 
    } catch (FacebookApiException $e) { 
    //you should use error_log($e); instead of printing the info on browser 
    d($e); // d is a debug function defined at the end of this file 
    $user = null; 
    } 
} 

if (!$user) { 
    echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>"; 
    exit; 
} 

//get user basic description 
$userInfo   = $facebook->api("/$user"); 

function d($d){ 
    echo '<pre>'; 
    print_r($d); 
    echo '</pre>'; 
} 



$signed_request = $facebook->getSignedRequest(); 
$page_id = $signed_request['page']['id']; 



$_SESSION['pageID']=$page_id; 

$_SESSION['userID'] = $user; 


?>

尝试注释掉这一行： 回声 “top.location.href = '$ loginUrl';”;

我相信在标签页上登录的默认行为是保留在该标签页上。你不必告诉它去那里。
