将加密的 swf 加载到 flex builder 中的 swfLoader

Question

我想将加密的 swf 加载到 flex builder 中的 SWFLoader 中。这是我尝试过的代码。 我收到一个错误 TypeError: Error #1006: value is not a function. 请给我解决方案。我要制作加密的 swf 加载器。

如果不考虑您正在做的事情的加密/解密方面，您需要在 Loader 类中使用的方法是 loadBytes()，它将异步地将 ByteArray 解析为图像或 SWF在你的情况下。

以下是您可以使用的方法：

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml"
                    xmlns:ns1="*"
                    width="100%" height="100%" layout="absolute" name="Content"
                    showStatusBar="false" applicationComplete="decrypt()">

        import flash.display.Loader;
        import flash.net.FileFilter;
        import flash.net.FileReference;
        import flash.utils.ByteArray;
        import flash.events.Event;
        import flash.system.LoaderContext;

        import mx.controls.Alert;
        import mx.controls.SWFLoader;
        import mx.preloaders.Preloader;

        private var decryptionLoader:Loader;
        private static var stream:FileStream;
        private static var stream2:FileStream;
        private static var file:File;

        private var fileToEncrypt:ByteArray;


        private function decrypt():void
        {

            file = File.documentsDirectory.resolvePath("E:/Sampal.swf");

            fileToEncrypt = new ByteArray;

            stream = new FileStream();
            stream.open( file, FileMode.READ );
            stream.readBytes(fileToEncrypt);
            stream.close();

            var key:ByteArray = Hex.toArray("gayan123");
            var aes:AESKey = new AESKey(key);

            aes.decrypt(fileToEncrypt);

            decryptionLoader = new Loader();
            decryptionLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, decryptionLoader_complete);
            var lc:LoaderContext = new LoaderContext();
            lc.allowLoadBytesCodeExecution = true; 
            decryptionLoader.loadBytes(fileToEncrypt, lc);

            //stream2 = new FileStream();
            //stream2.open( file, FileMode.READ);
            //stream2.writeBytes(fileToEncrypt);
            //stream2.close();
        }

        private function decryptionLoader_complete(evt:Event):void {
            decryptionLoader.contentLoaderInfo.removeEventListener(Event.COMPLETE, loader_complete);
            //Your SWF has now been parsed and is ready to use e.g.:
            this.addChild(decryptionLoader.content);
