将使用Flash捕获的图像传递到Asp.net页面

我正在使用ActionScript 3通过我的一个Asp.net页面中的用户网络摄像头捕获图像。这是我正在使用的代码

   package 
{
    import flash.display.Sprite;
    import flash.media.Camera;
    import flash.media.Video;
    import flash.display.BitmapData;
    import flash.display.Bitmap;
    import flash.events.MouseEvent;
    import flash.net.FileReference;
    import flash.utils.ByteArray;
    import com.adobe.images.JPGEncoder;
    import com.dynamicflash.util.Base64;

     import flash.net.URLLoader;
    import flash.net.URLRequest;
    import flash.net.URLRequestMethod;
    import flash.net.URLVariables;





    public class Main extends Sprite
    {
        private var camera:Camera = Camera.getCamera();
        private var video:Video = new Video();
        private var bmd:BitmapData = new BitmapData(320,240);
        private var bmp:Bitmap;
        private var fileReference:FileReference = new FileReference();
        private var byteArray:ByteArray;
        private var jpg:JPGEncoder = new JPGEncoder();
        private var _uploadPath:String = "/Upload.aspx";







        public function Main():void
        {

            saveButton.visible = false;
            discardButton.visible = false;

            saveButton.addEventListener(MouseEvent.MOUSE_UP, saveImage);
            discardButton.addEventListener(MouseEvent.MOUSE_UP, discard);
            capture.addEventListener(MouseEvent.MOUSE_UP, captureImage);

            if (camera != null)
            {

                video.smoothing = true;
                video.attachCamera(camera);
                video.x = 140;
                video.y = 40;
                addChild(video);
            }
            else
            {
                trace("No Camera Detected");
            }
        }

        private function captureImage(e:MouseEvent):void
        {
            bmd.draw(video);
            bmp = new Bitmap(bmd);
            bmp.x = 140;
            bmp.y = 40;
            addChild(bmp);

            capture.visible = false;
            saveButton.visible = true;
            discardButton.visible = true;
        }

        private function saveImage(e:MouseEvent):void
        {
            byteArray = jpg.encode(bmd);
            var base64Bytes:String = Base64.encodeByteArray(byteArray);
            var vars:URLVariables = new URLVariables();
            vars.imageData = base64Bytes;

            // and send it over the wire via HTTP POST
            var url:URLRequest = new URLRequest(_uploadPath);
            url.data = vars;
            url.method = URLRequestMethod.POST;

            var loader:URLLoader = new URLLoader();
            loader.load(url);



            //fileReference.save(byteArray, "Image.jpg");


            removeChild(bmp);
            saveButton.visible = false;
            discardButton.visible = false;
            capture.visible = true;
        }

        private function discard(e:MouseEvent):void
        {
            removeChild(bmp);
            saveButton.visible = false;
            discardButton.visible = false;
            capture.visible = true;
        }
    }
}

在这里，使用文件引用保存图像，提示用户保存。但是，我希望图像应该发送到asp.net页面或服务器，这样我就可以获取图像并将其保存到数据库中，这样你们就可以指导我如何继续了， 非常感谢您的任何建议。

谢谢

您可以执行以下操作：

（未经测试的代码）

以及您的事件处理程序：

private function uploadJPGComplete(evt:Event):void {
    //Handle server response via evt.target.data

    //Optionally do your stuff after uploading, if it makes sense here
    removeChild(bmp);
    saveButton.visible = false;
    discardButton.visible = false;
    capture.visible = true;
}

private function uploadJPGIOError(evt:IOErrorEvent):void {
    //Something went wrong while trying to talk to the server   
}

---

当然，你还需要做服务器端的一半，但这应该可以满足你在Flash客户端的需要，可能还需要一些小技巧。

，非常感谢你的关注，但我无法理解asp.net端，，，一旦它发送了图像，我就必须在我的aspx页面上处理它，对吗/

private function uploadJPGComplete(evt:Event):void {
    //Handle server response via evt.target.data

    //Optionally do your stuff after uploading, if it makes sense here
    removeChild(bmp);
    saveButton.visible = false;
    discardButton.visible = false;
    capture.visible = true;
}

private function uploadJPGIOError(evt:IOErrorEvent):void {
    //Something went wrong while trying to talk to the server   
}
