Plupload 怎么传参数给后台页

[wrost]

我的MVC3程序，用Plupload作为上传组件
组件地址：http://www.plupload.com

我现在设置了后台页面，后台页面也可以接收到上传的文档：
runtimes: 'gears,flash,silverlight,browserplus,html5', // 这里是说用什么技术引擎
url: 'LibAddEdit', // 服务端上传路径

问题：我想把一个参数传递给后台页，比如GUID，请问该怎么做？

@{
    ViewBag.Title = "LibAddEdit2";
    Layout = "~/Views/Shared/_Admin.cshtml";
}
@section Header{
@* <style type="text/css">@Url.Content("Scripts/jquery.plupload.queue/css/jquery.plupload.queue.css");</style>*@

现在发现，放到MVC里边，一个文件怎么分成4次向后台相应，导致文件分成4次来保存

相当于一个文件被分成了4块，文件就不能打开了。

现在找到方法了： 感谢Webdiyer大哥提供帮助 http://blog.cdeutsch.com/2011/02/plupload-and-aspnet-mvc3.html Plupload 提交到服务端的处理代码如下： 最好用谷歌浏览器进行调试，可以看到提交的参数、参数值

/// <summary>  
/// Handles chuncked file uploads like the ones from plupload.  
/// </summary>  
/// <param name="chunk"></param>  
/// <param name="name"></param>  
/// <returns></returns>  
[HttpPost]  
public ActionResult Upload(int? chunk, string name)  
{  
    var fileUpload = Request.Files[0];  
    var uploadPath = Server.MapPath("~/App_Data/Uploads");  
    chunk = chunk ?? 0;  
  
    //UPDATE 2/17/2011: Removed this since it doesn't work. I recommend setting the unique_names param client side if you want unique names.  
    ////find a free filename if this is the first chunk  
    //if (!chunk.HasValue || chunk < 1)  
    //{  
    //    int xx = 1;  
    //    while (System.IO.File.Exists(uploadedFilePath))  
    //    {  
    //        uploadedFilePath = Path.Combine(uploadPath, Path.GetFileNameWithoutExtension(name) + "_" + xx + Path.GetExtension(name));  
    //        xx++;  
    //    }  
    //}  
      
    //TODO: cleanup old files  
  
    //write chunk to disk.  
    string uploadedFilePath = Path.Combine(uploadPath, name);  
    using (var fs = new FileStream(uploadedFilePath, 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("Success", "text/plain");  
}

我知道两种：（都是对URL操作） 1. 初始化的时候： url: '/upload.aspx?id='+Id 2. 之后的任意时刻：uploader.settings.url = uploadersettings.url + '?token=' + myToken; 参考自：http://stackoverflow.com/questions/13367897/unable-to-pass-additional-parameters-in-plupload
