是的，您可以使用 FileReference。
这基本上就是它的完成方式：

var bytes:ByteArray = new ByteArray();
var fileRef:FileReference=new FileReference();
fileRef.save("fileContent", "fileName");

看起来不太难，不是吗？
这里还有一个视频教程：

希望有帮助。

Yes you can, with FileReference.
This is basically how it's done:

var bytes:ByteArray = new ByteArray();
var fileRef:FileReference=new FileReference();
fileRef.save("fileContent", "fileName");

Doesn't look too hard, does it?
And here's a video-tutorial on it too:

Hope that helps.

由于我有一个将字节输出到文件的函数（因为我正在使用位图做一些事情），所以我也重用它来输出字符串，如下所示：

var filename:String = "/Users/me/path/to/file.txt";
var byteArray:ByteArray = new ByteArray();
byteArray.writeUTFBytes(someString);
outFile(filename, byteArray);

private static function outFile(fileName:String, data:ByteArray):void {
    var outFile:File = File.desktopDirectory; // dest folder is desktop
    outFile = outFile.resolvePath(fileName);  // name of file to write
    var outStream:FileStream = new FileStream();
    // open output file stream in WRITE mode
    outStream.open(outFile, FileMode.WRITE);
    // write out the file
    outStream.writeBytes(data, 0, data.length);
    // close it
    outStream.close();
}

Since I had a function to output bytes to a file (because I was doing something with bitmaps), I reused it to output a string as well, like this:

var filename:String = "/Users/me/path/to/file.txt";
var byteArray:ByteArray = new ByteArray();
byteArray.writeUTFBytes(someString);
outFile(filename, byteArray);

private static function outFile(fileName:String, data:ByteArray):void {
    var outFile:File = File.desktopDirectory; // dest folder is desktop
    outFile = outFile.resolvePath(fileName);  // name of file to write
    var outStream:FileStream = new FileStream();
    // open output file stream in WRITE mode
    outStream.open(outFile, FileMode.WRITE);
    // write out the file
    outStream.writeBytes(data, 0, data.length);
    // close it
    outStream.close();
}
