功能：

/* Function to make a generic HTTP Request 
* loc = location e.g. http://www.google.com 
* req = request 
* type = content type 
* complete = function to execute when HTTP req returns with complete 
*/ 
    public function httpReq(loc:String , req:String, type:String, complete:Function):void{ 
       /* Start the HTTP Request */ 
       try{ 
        requestSender= new URLLoader(); 
        requestSender.addEventListener(Event.COMPLETE, complete); 
        requestSender.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, printResponse); 
        var urlRequest :URLRequest = new URLRequest(loc); 

        /* Setup HTTP Request */ 
        urlRequest.data = req; 
        urlRequest.contentType = type; 
        urlRequest.method = URLRequestMethod.GET; 
        requestSender.load(urlRequest); // Send the request off, when complete jump to completeHandler 
        } 
       catch(e:Error){ 
         trace(e.message); 
         trace(e.getStackTrace()); 
        } 
       }

得到響應：

/* HTTP Request complete, back with response */ 
private function responseHandler(event:Event):void 
{ 
    this.requestSender = URLLoader(event.target); // Set requestSender as response 
    this.output.text = this.requestSender.data; // Get its data 
    trace("THE DATA IS "+this.requestSender.data); 
    this.requestSender.close(); 
    alert.cancel(); 
}

調用示例：

httpReq("http://www.google.com" , "requestString", "application/x-www-form-urlencoded", responseHandler);
