Flash录音机，如何在不保存本地文件的情况下，上传录音至服务器（SSH）

小弟目前在做一个网页录音的小东西

想用Flash实现

已经在AS中获取到了录音的文件对象

现不知如何上传至后台

后台使用的是Struts + Spring + Hibernate

在Action中的.do里面接不到所传参数

求解答，最好能有可参考的代码

部分代码如下：

AS中:

private function onRecordComplete(event:Event):void  
{  
    _display.text = "Playing recorded sound.";  
    player = new WavSound(recorder.output);  
  
    //压缩  
    this.recorder.output.compress();  
    player.play();  
    //_file.upload(uploadUrl,uploadFileName,false);  
    //_file.save( recorder.output, "recorded.wav" );  
    //上传操作  
    var url:URLRequest = new URLRequest(uploadUrl.url + "?testParam=1");  
    url.contentType = "application/octet-stream";  
    url.method = URLRequestMethod.POST;  
      
    url.data = recorder.output;  
    url.url += "?" + uploadFileName + "FileName=" + uploadFileName + "&" + uploadFileName + "ContentType=" + url.contentType;  
    _display.text = "onRecordComplete_2:" + url.url;  
    this.loader.dataFormat = URLLoaderDataFormat.BINARY;  
    this.loader.addEventListener(Event.COMPLETE, this.completeHandler);  
    this.loader.addEventListener(ProgressEvent.PROGRESS, this.progressHandler);  
    this.loader.load(url);  
}
