ActionScript3：如何获取放置swf的页面的真实url？

Question

所以我尝试了

            var url:String = String(this.loaderInfo.url);
            var request:URLRequest = new URLRequest(url);
            try {
                navigateToURL(request, '_self'); // second argument is target
            } catch (e:Error) {
                ErrorButton.label = "Please refresh page manually"
            }

and

            var url:String = String(this.loaderInfo.loaderURL);
            var request:URLRequest = new URLRequest(url);
            try {
                navigateToURL(request, '_self'); // second argument is target
            } catch (e:Error) {
                ErrorButton.label = "Please refresh page manually"
            }

和 FlexGlobals.topLevelApplication.url 但它都给出了相同的 =(

但 thay bouth 返回我到 http://127.0.0.1/w2/window.swf 而我有 url http://127.0.0.1/w2/window.php?action=read#1。那么我该怎么做才能接收真正的完整链接 - 而不是 swf 链接？

怎么样

var _url:String = flash.external.ExternalInterface.call("window.location");
