Question

我的目标是将嵌入资源写入文件

[Embed(source="Embed/viewer.js", mimeType="application/octet-stream")]
private var viewer_js:Class;

[Embed(source="Embed/viewer2.js", mimeType="application/octet-stream")]
private var viewer2_js:Class;


private function writeAssetToFile(embed:Class, targetFileName:String):void {
    var file:File = File.desktopDirectory.resolvePath(targetFileName);
    var fs:FileStream = new FileStream();
    fs.open(file, FileMode.WRITE);

    fs.writeBytes(embed as ByteArray); // error here
    fs.close(); 
}

例如：

 writeAssetToFile(viewer_js,"viewer.js");

fs.writeBytes（嵌入为ByteArray）;是造成问题的一条线。

你只需编写一个类的实例，如下所示：

private function writeAssetToFile(embed:Class, targetFileName:String):void {
    var file:File = File.desktopDirectory.resolvePath(targetFileName);
    var fs:FileStream = new FileStream();
    fs.open(file, FileMode.WRITE);
    fs.writeBytes(new embed() as ByteArray); // here, should fix
    fs.close(); 
}

诀窍是，嵌入application/octet-stream的任何内容都被实例化为ByteArray后代，因此您不需要再做任何事情。

如何将嵌入文件写入磁盘？
