是否有可能到选定的图像转换成的base64 EN codeD字符串？

Is it possible to convert an selected image into base64 encoded string?

将图像上传好的和简单的解决方案。 ：）

Would be nice and easy solution for image uploader. :)

推荐答案

如果你想连接code加载图像的字节数组，你可以从mx.utils使用Base64En codeR类Base64En$c$cr.

If you're wanting to encode the byteArray of a loaded image, you could use the Base64Encoder class from mx.utils Base64Encoder.

是这样的：

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
loader.load(new URLRequest("img.jpg"));

function loadComplete(e:Event):void {
    loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, loadComplete);
    var bmd:BitmapData = Bitmap(e.target.content).bitmapData;
    var ba:ByteArray = bmd.getPixels(new Rectangle(0,0,bmd.width,bmd.height));
    var b64:Base64Encoder = new Base64Encoder();
    b64.encodeBytes(ba);
    trace(b64.toString());
}

我不得不追查类here.

此外，还有，我发现，但没有这里测试另外的Base64类......但看起来像它的工作原理类似。

Also, there's another Base64 class that I found but haven't tested here...but looks like it works similarly.

希望有所帮助。
