as3预加载器从缓存中停止加载swf?

标签: actionscript-3 caching flash preloader

对不起,如果这已经在其他地方得到解答,但我找不到任何匹配的内容。

我有两个swfs;预加载器(让我们称之为A)和一些内容(B)。加载B并将其作为孩子添加。一切都很美好(你甚至可以看到here)。

我只有一个小问题。通常在使用URLLoader类加载(例如图像)到flash时,我将+ "?" + new Date().getTime()添加到URLRequest以强制flash加载目标的最新版本,换句话说,使用缓存版本来停止它。现在,当我尝试将B添加到A的Loader时,它找不到URL(#2035 URL not found)。所以我的问题是:我正在尝试做什么,或者我应该采取另一种方法来阻止B缓存?

这是预加载器代码:

package 
{
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    import flash.display.Loader;
    import flash.net.URLRequest;
    import flash.events.ProgressEvent;
    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.events.ErrorEvent;
    import flash.net.URLLoader;
    import flash.text.TextField;

    public class claude_loader extends MovieClip
    {
        public var main_movie:Loader = new Loader();
        public var rss_loader:URLLoader;
        private var perc_text:TextField = new TextField();
        public function claude_loader()
        {
            stage.align = StageAlign.TOP_LEFT;
            stage.scaleMode = StageScaleMode.NO_SCALE;
            with (perc_text)
            {
                x = this.stage.stageWidth / 2;
                y = this.stage.stageHeight / 2;
            }
            addChild(perc_text);
            main_movie.load(new URLRequest("claudia_summers.swf"+ "?" + new Date().getTime()));
            main_movie.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, load_progress);
            main_movie.contentLoaderInfo.addEventListener(Event.COMPLETE,on_complete);
        }
        public function load_progress(e:ProgressEvent):void
        {
            var perc:Number = Math.round((e.bytesLoaded/e.bytesTotal)*100);
            perc_text.text = "Loading " + perc + "%";
            if (e.bytesLoaded == e.bytesTotal)
            {
                perc_text.text = "Loading done";
            }
        }
        public function on_complete(e:Event):void
        {
            rss_loader = new URLLoader(new URLRequest("http://news.sulsc.org/feed"));
            rss_loader.addEventListener(Event.COMPLETE,rss_complete);
            perc_text.text = "Loading RSS";
        }
        public function rss_complete(e:Event):void
        {
            MovieClip(main_movie.content).rss_xml = XML(e.target.data);
            addChild(main_movie);
        }

    }
}

不确定如何/为什么,但在String()周围添加new Date().getTime()并为main_movie提供IOErrorEvent侦听器可以解决问题。我想我在某个地方有一个错误,因为这肯定应该没有这些添加,但不是吗?无论如何感谢为你提供所有帮助!

工作代码:

    import flash.events.IOErrorEvent;

    public class claude_loader extends MovieClip
    {

        public function claude_loader()
        {

            stage.scaleMode = StageScaleMode.NO_SCALE;
            with (perc_text)
            {
                x = this.stage.stageWidth / 2;
                y = this.stage.stageHeight / 2;
                textColor = 0xFFFFFF;
            }
            addChild(perc_text);
            main_movie.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,catch_error);
            main_movie.load(new URLRequest("claudia_summers.swf" + "?" + String(new Date().getTime())));
            function catch_error(e:IOErrorEvent):void
            {
            main_movie.load(new URLRequest("claudia_summers.swf"));
            perc_text.text = "Failed non-cache load"
            }
            main_movie.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, load_progress);
            main_movie.contentLoaderInfo.addEventListener(Event.COMPLETE,on_complete);
        }
        public function load_progress(e:ProgressEvent):void
        {
            var perc:Number = Math.round((e.bytesLoaded/e.bytesTotal)*100);
            perc_text.text = "Loading " + perc + "%";
            if (e.bytesLoaded == e.bytesTotal)
            {
                perc_text.text = "Loading done";
            }
        }
        public function on_complete(e:Event):void
        {
            rss_loader = new URLLoader(new URLRequest("http://news.sulsc.org/feed"));
            rss_loader.addEventListener(Event.COMPLETE,rss_complete);
            perc_text.text = "Loading RSS";
        }
        public function rss_complete(e:Event):void
        {
            MovieClip(main_movie.content).rss_xml = XML(e.target.data);
            addChild(main_movie);
        }

    }
