AS3 POST请求作为GET发送

这是我的AS3

public function save(page:SharedPageVO, callback :Function = null): void {
   var req:URLRequest = new URLRequest( "service.asmx/CreateSharedPage" );
   req.data = page;
   req.method = URLRequestMethod.POST;
   if (callback != null)
   {
    //handle removing the event here instead of there
    this.complete = callback;
    DataService.instance.addEventListener(Event.COMPLETE, onComplete);
   }
   DataService.instance.load( req );
}

public var complete:Function;
private function onComplete(e:Event)
{
 if (complete != null) complete(e);
 complete = null;
 DataService.instance.removeEventListener(onComplete);
}

这似乎是flash的一个问题,因为它甚至在进入服务器之前就已经发生了。我已经上传到一个测试服务器,我仍然认为这是一个得到通过。任何帮助都将不胜感激。谢谢。
