外部JSON文件是未知類型

我有這段代碼，我試圖加載一個JSON文件並解析它。但是，當我試圖用我做了一個類加載它（我可以加載圖像和聲音），它給了我這個錯誤：外部JSON文件是未知類型

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

這是我用來加載它的功能，我怎樣才能使它所以Flash可以識別文件類型？

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文件的內容是使用Flash CS6中新的Spritesheet方法生成的。

你可以發佈'Sheet1.json'的內容嗎？你如何提供這個文件？ – Florent 2012-08-02 11:54:50

我用內容編輯了文件，它現在只是作爲一個字符串來獲取它，但是不會給出錯誤。該錯誤是由IOError處理程序生成的。 – tversteeg 2012-08-02 12:04:48

當您在瀏覽器中點擊「http：// 192.168.1.19/Sheet1.json」時會發生什麼？ – Florent 2012-08-02 12:25:34

在互聯網上經過一番研究，我發現這個問題，Flash用戶對圖像的默認加載器，聲音和SWF文件。您必須使用URLLoader來加載其他文件。我使用這個函數成功加載文本文件，LoaderEvent是一個自定義事件類，我用它來傳遞Strings：

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)); 
     } 
}
