ActionScript3：如何获取放置swf的页面的真实URL？

Question

所以我试过

            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"
            }

和

            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但它们都给出了相同的=（

但是当我有网址http://127.0.0.1/w2/window.swf时，我会回复http://127.0.0.1/w2/window.php?action=read#1。我使用flash builder。那么我该怎样做才能获得真正的完整链接 - 而不是swf链接？

怎么样？

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