I am using plupload version 1.3.0
More specifically how I have to define my controller action to support chunking? Can I use the HttpPosteFileBase as a parameter?
At the moment I am using the following code to initialize the plugin
In the HEAD tag
<link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/jquery.ui.plupload.css" )%>" /> <link type="text/css" rel="Stylesheet" media="screen" href="<%: Url.Content( "~/_assets/css/plupload/gsl.plupload.css" )%>" /> <script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/gears_init.js" )%>"></script> <script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/plupload.full.min.js" )%>"></script> <script type="text/javascript" src="<%: Url.Content( "~/_assets/js/plupload/jquery.ui.plupload.min.js" )%>"></script>
On document ready
$("#uploader").pluploadQueue({ runtimes: 'html5,html4,gears,flash,silverlight', url: '<%: Url.Content( "~/Document/Upload" ) %>', max_file_size: '5mb', chunk_size: '1mb', unique_names: true, filters: [ { title: "Documenti e Immagini", extensions: "doc,docx,xls,xlsx,pdf,jpg,png" } ], multiple_queues: false });
回答1:
Here you go:
[HttpPost] public ActionResult Upload(int? chunk, string name) { var fileUpload = Request.Files[0]; var uploadPath = Server.MapPath("~/App_Data"); chunk = chunk ?? 0; using (var fs = new FileStream(Path.Combine(uploadPath, name), chunk == 0 ? FileMode.Create : FileMode.Append)) { var buffer = new byte[fileUpload.InputStream.Length]; fileUpload.InputStream.Read(buffer, 0, buffer.Length); fs.Write(buffer, 0, buffer.Length); } return Content("chunk uploaded", "text/plain"); }
This method will be called multiple times for each chunk and for each file being uploaded. It will pass as parameter the chunk size and the filename. I am not sure as to whether you could use a HttpPostedFileBase as action parameter because the name is not deterministic.

Look here:
$("#uploader").pluploadQueue({ // General settings runtimes: 'silverlight', url: '/Home/Upload', max_file_size: '10mb', chunk_size: '1mb', unique_names: true, multiple_queues: false, // Resize images on clientside if we can resize: { width: 320, height: 240, quality: 90 }, // Specify what files to browse for filters: [ { title: "Image files", extensions: "jpg,gif,png" }, { title: "Zip files", extensions: "zip" } ], // Silverlight settings silverlight_xap_url: '../../../Scripts/upload/plupload.silverlight.xap' }); // Client side form validation $('form').submit(function (e) { var uploader = $('#uploader').pluploadQueue(); // Files in queue upload them first if (uploader.files.length > 0) { // When all files are uploaded submit form uploader.bind('StateChanged', function () { if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) { $('form')[0].submit(); } }); uploader.start(); } else { alert('You must queue at least one file.'); } return false; });
And in Controller:
[HttpPost] public string Upload( ) { HttpPostedFileBase FileData = Request.Files[0]; if ( FileData.ContentLength > 0 ) { var fileName = Path.GetFileName( FileData.FileName ); var path = Path.Combine( Server.MapPath( "~/Content" ), fileName ); FileData.SaveAs( path ); } return "Files was uploaded successfully!"; }
That's all...No chunk is needed in Controller...
