如何使用Plupload.js将数据发送到服务器？

Question

现在，我在我的ASP Net MVC应用程序中使用plupload。我一直在向服务器（我的控制器）发送数据， 代码如下： 谢谢您的帮助；

engine = sqlalchemy.create_engine('mssql+pyodbc://'+user+':'+password+'@'+host+':'+port+'/'+database+'?'\
      +'driver=SQL+Server+Native+Client+11.0')

videoUploadHandler.ashx

 var blob = "";
        var fileObject = new File([blob], fileName, {
            type: 'video/mp4'
        });
 var uploader = new plupload.Uploader({
            runtimes: 'html5,html4',
            url: "/videoUploadHandler.ashx",
            chunk_size: '5mb',
            multi_selection: true,
            unique_names: false,
            filters: {
                mime_types: [

                     { title: "video files", extensions: "avi,mp4,mov,mwm,mkv" }
                ]
            }
        });
        uploader.init();
        uploader.files.push(fileObject);
        uploader.start();
