AS3-显示Flash和PHP之间的数据传输进度

Question

How to display the progress on a data transfer between Flash and PHP? Below is the AS3 code I'm using to upload a base64 encoded image through PHP.

var scriptLoader:URLLoader = new URLLoader();
var scriptVars:URLVariables = new URLVariables();

var scriptRequest:URLRequest = new URLRequest("https://www.example.com/sendit.php");

var imagedata = Base64.encode(mybitmap);
scriptVars.theimage = imagedata

scriptRequest.method = URLRequestMethod.POST;
scriptRequest.data = scriptVars;
scriptLoader.load(scriptRequest);

(Server is running PHP Version 5.3.10)

You can add an event listener on scriptRequest for ProgressEvent.PROGRESS to monitor load completion. The event callback will contain bytesLoaded and bytesTotal to monitor.

ProgressEvent reference: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/ProgressEvent.html

scriptRequest.addEventListener(ProgressEvent.PROGRESS, onProgress);

function onProgress(e:ProgressEvent):void {
   trace(e.bytesLoaded + " of " + e.bytesTotal);
}
