Question

所以，我在MVC3中使用flash运行时实现了plupload。

它工作得很完美，因为它使用更正操作上传并运行它。但是，我真的希望能够控制响应，并在plupload中处理它，但我似乎无法得到任何响应。

我已经尝试重写fileUploaded，但我似乎无法从参数中获取任何内容。我已经尝试过返回简单的字符串，json以及你有什么。我似乎无法在客户端获得任何东西。当然通过flash发送，我甚至无法用firebug调试请求：/

与Error事件相同，并抛出异常。它正确地将异常解释为错误，但总是#IO ERROR与某些代码（如2038）或其他东西出现在另一端。我无法显示我的异常字符串或任何内容。有人可以帮忙吗？

奖金问题：我如何发送会话/ cookie数据以及plupload，以便我可以在我的操作中访问会话？

Answer 1

以下对我有用：

[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 Json(new { message = "chunk uploaded", name = name });
}

并在客户端：

$('#uploader').pluploadQueue({
    runtimes: 'html5,flash',
    url: '@Url.Action("Upload")',
    max_file_size: '5mb',
    chunk_size: '1mb',
    unique_names: true,
    multiple_queues: false,
    preinit: function (uploader) {
        uploader.bind('FileUploaded', function (up, file, data) {
            // here file will contain interesting properties like 
            // id, loaded, name, percent, size, status, target_name, ...
            // data.response will contain the server response
        });
    }
});

就奖金问题而言，我愿意通过不使用会话来回答它，因为它们不能很好地扩展，但是因为我知道你可能不会喜欢这个答案你有可能使用multipart_params：

在请求中传递会话ID

multipart_params: {
    ASPSESSID: '@Session.SessionID'
},

然后在服务器perform some hacks上创建正确的会话。

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!";
       }

全部......控制器中不需要块...

使用带有MVC3的plupload
