AS3 實現讀取本地數據

應用此文，必須在SWF文件同目錄想建一個文件request.txt，在這個文件裏輸入一定內容。。。你會在flash控制檯看到她。。
package  {
	
	import flash.display.MovieClip;
	import flash.display.Sprite;
	import flash.net.*;
	import flash.events.*;
	
	public class AA extends MovieClip {
		
		
		public function AA() {
			// constructor code
			var loader:URLLoader = new URLLoader();
			conf(loader);
			var req:URLRequest = new URLRequest("request.txt");
			req.method = URLRequestMethod.POST;
			loader.load(req);
		}
		public function conf(evt:IEventDispatcher):void{
			evt.addEventListener(Event.COMPLETE,completehandler);
			/*evt.addEventListener(Event.OPEN,openHandler);
			evt.addEventListener(ProgressEvent.PROGRESS,progressHandler);
			evt.addEventListener(SecurityErrorEvent.SECURITY_ERROR,securityHandler);
			evt.addEventListener(HTTPStatusEvent.HTTP_STATUS,httpHandler);
			evt.dispatchEvent(IOErrorEvent.IO_ERROR,ioErronHandler);*/
		}
		public function completehandler(ev:Event):void{
			var lod:URLLoader = URLLoader(ev.target);
			trace("complete加載："+lod.data);
		}
	}
	
}
