AS3当我用装载机，我总是得到则httpStatus code 200事件虽然则httpStatus code。在谷歌浏览器304 [英] As3 When i use Loader,i always get httpstatus code 200 event though the httpstatus code in google chrome is 304

问题描述

在AS3，我用

_loader.contentLoaderInfo.addEventListener(HTTPStatusEvent.HTTP_STATUS, onHttpStatus);

检测装载机的则httpStatus code。在回调函数则httpStatus code为200时，则httpStatus code。在谷歌浏览器显示的是完全304。

to detect the httpstatus code of Loader. In the callback function the httpstatus code is 200 when the httpstatus code show in google chrome is exactly 304.

推荐答案

使用随机数生成的新的联系，避免缓存效果

Use a random number to generate "new" links and avoid the cache effect

    var loader:URLLoader = new URLLoader();
    var noCache:Number = Math.random()
    loader.addEventListener(
        HTTPStatusEvent.HTTP_STATUS, 
        function(e:HTTPStatusEvent):void {
            trace('http status : ' + e.status)
        } 
    )
    loader.load(new URLRequest('http://www.example.com?c='+noCache));
