我有这段代码，我试图加载一个 JSON 文件并解析它。但是当我尝试用我制作的类加载它（我可以加载图像和声音）时，它给了我这个错误：

Error #2124: Loaded file is an unknown type. URL: http://192.168.1.19/Sheet1.json

这是我用来加载它的函数，我怎样才能让它让 Flash 识别文件类型？

    public function LoadString(path:String) {
        var stringLoader:flash.display.Loader = new flash.display.Loader();
        stringLoader.contentLoaderInfo.addEventListener(LoaderEvent.COMPLETE, loadStringComplete);
        stringLoader.contentLoaderInfo.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpError,false,0,true);
        stringLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, error, false, 0 ,true);
        stringLoader.load(new URLRequest(path));
    }

    private function loadStringComplete(e:Event) {
        try {
            dispatchEvent(new LoaderEvent(LoaderEvent.STRING_LOADED,0,0,e.target.data,true));
        } catch (error:*) {
            dispatchEvent(new LoaderEvent(LoaderEvent.ERROR,0,0,"Error: "+ error.toString(),true));
        }
    }

JSON 文件的内容是使用 Flash CS6 中的新 Spritesheet 方法生成的。

在互联网上进行了一些研究后，我发现了问题，Flash 使用了图像、声音和 swf 文件的默认加载器。您必须使用 URLLoader 来加载其他文件。我使用这个函数成功加载了文本文件，LoaderEvent 是一个自定义事件类，我用它传递字符串：

public function LoadString(path:String) {
        var stringLoader:URLLoader = new URLLoader(new URLRequest(path));
        stringLoader.addEventListener(LoaderEvent.COMPLETE, loadStringComplete);
        stringLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpError,false,0,true);
        stringLoader.addEventListener(IOErrorEvent.IO_ERROR, error, false, 0 ,true);
}

private function loadStringComplete(e:Event) {
        try {
            dispatchEvent(new LoaderEvent(LoaderEvent.STRING_LOADED,0,0,e.target.data,true));
        } catch (error:*) {
            dispatchEvent(new LoaderEvent(LoaderEvent.ERROR,0,0,"Error: "+ error.toString(),true));
        }
}
