當運行Facebook應用程序時出錯

Question

我在Facebook上創建了一個測試應用程序，所以我試圖訪問用戶信息，以便在創建$ facebook-> getSession（）時向我顯示此提示用戶接受窗口錯誤：

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /nfs/c05/h01/mnt/78225/domains/apps.royalworkshop.com/html/fb/index.php:2) in /nfs/c05/h01/mnt/78225/domains/apps.royalworkshop.com/html/fb/src/facebook.php on line 37 

Fatal error: Call to undefined method Facebook::getSession() in /nfs/c05/h01/mnt/78225/domains/apps.royalworkshop.com/html/fb/index.php on line 14 

有人知道如何解決這個問題，我不是服務器上的大師或更少...謝謝！

更改爲$ facebook-> getUser（）;代替。這是在php-sdk 3.1.1中使用的。最近的版本。您可能需要更新。這裏 https://developers.facebook.com/docs/reference/php/

$user = $facebook->getUser(); 
if ($user) { 
    try { 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api('/me'); 
    } catch (FacebookApiException $e) { 
    error_log($e); 
    $user = null; 
    } 
}
