從私人Facebook消息獲取附件，使用fql

如何使用fql獲取我的iOS應用程序附件從Facebook私人消息？從私人Facebook消息獲取附件，使用fql

我讓FQL請求：

SELECT +正文，附件，源，CREATED_TIME，AUTHOR_ID，MESSAGE_ID，viewer_id + FROM +消息+ WHERE +的thread_id =％@

和接收回應：但沒有相關的附件。

{ 
    attachment =  { 
     caption = ""; 
     description = ""; 
     "fb_object_id" = ""; 
     "fb_object_type" = ""; 
     icon = "https://fbstatic-a.akamaihd.net/rsrc.php/v2/yD/r/aS8ecmYRys0.gif"; 
     media =   (
     ); 
     name = ""; 
     properties =   (
     ); 
     "tagged_ids" =   (
     ); 
    }; 
    "author_id" = 100006578915973; 
    body = ""; 
    "created_time" = 1392226769; 
    "message_id" = "249232388588208_0"; 
    source = 32; 
    "viewer_id" = 100002767455960; 
}
