我正在使用plupload版本 1.3.0

更具体地说，我必须如何定义我的控制器操作以支持分块？我可以使用HttpPosteFileBase作为参数吗？

目前我正在使用以下代码来初始化插件

在 HEAD 标签中

<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>

准备好文件

$("#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
});

干得好：

[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");
}

对于每个块和正在上传的每个文件，都会多次调用此方法。它将作为参数传递块大小和文件名。我不确定您是否可以使用HttpPostedFileBaseas 操作参数，因为名称不确定。

看这里：

$("#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;
      });

在控制器中：

[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!";
       }

就是这样......控制器中不需要任何块......
