Facebook PHP SDK v4 $ session登錄後無效

Question

這是我的工作流程。用戶轉到index.php並重定向到Facebook登錄。登錄後，他們被重定向到post.php，我有效的$session。我能夠在本地工作，但只要我將其上傳到我的服務器，$session變量就會返回NULL。

這是我的代碼post.php。

session_start(); 

require_once("../assets/resources/constants.php"); 
require_once("autoload.php"); 


use Facebook\FacebookSession; 
use Facebook\FacebookRedirectLoginHelper; 
use Facebook\FacebookRequest; 
use Facebook\FacebookResponse; 
use Facebook\FacebookSDKException; 
use Facebook\FacebookRequestException; 
use Facebook\FacebookAuthorizationException; 
use Facebook\GraphObject; 

// init app with app id (APPID) and secret (SECRET) 
FacebookSession::setDefaultApplication(FACEBOOK_APP_ID,FACEBOOK_APP_SECRET); 

// login helper with redirect_uri 
$helper = new FacebookRedirectLoginHelper(BASE_URL."/facebook/post.php"); 

try { 
    $session = $helper->getSessionFromRedirect(); 
    if (isset($session)) $_SESSION['token'] = $session->getToken(); 
} catch(FacebookRequestException $ex) { 
    // When Facebook returns an error 
} catch(Exception $ex) { 
    unset($session); 
    echo $ex->getMessage(); 
} 

var_dump($session); 
exit(); 

我做了一些挖掘，並能夠得到這個錯誤拋出。

所以這個問題是在我的REDIRECT_URI額外/引起的。顯然它需要與Facebook上的完全匹配。刪除額外的斜槓解決了這個問題。
