無法重定向程序返回到其Facebook頁面標籤

Question

我剛剛創建了一個Facebook應用程序，這是我第一次嘗試，而作爲說明我在這個奇怪的情況stucked完成一切：

當用戶允許認證通過後應用程序會將我的瀏覽器重定向到Facebook以外的瀏覽器，並將其重定向到託管我網站的網站頁面，而不是重定向僅留在頁面選項卡中的iframe。

這可能是因爲在$redirect_uri我給其中的應用程序託管的網站的地址，但是當我嘗試將$redirect_uri改變應用程序的頁面標籤地址的Facebook給這個錯誤：

An error occurred. Please try again later.

<?php 
    include ('src/facebook.php');

     $signed_request = $facebook -> getSignedRequest(); 

     list($encoded_sig, $payload) = explode('.', $_REQUEST["signed_request"], 2); 
     $signed_request = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

試試這個。

$redirect_uri必須是你的Facebook頁面的網址，
和在Facebook的應用程序配置頁面標籤網址場必須是你主機路徑。
