MVC Valums Ajax Uploader - IE不会在request.InputStream中发送流

Question

我正在使用Valums Ajax上传器.所有在Mozilla中运行良好的代码:

视图:

var button = $('#fileUpload')[0];
var uploader = new qq.FileUploader({
    element: button,
    allowedExtensions: ['jpg', 'jpeg', 'png', 'gif'], 
    sizeLimit: 2147483647, // max size
    action: '/Admin/Home/Upload',
    multiple: false
});

控制器:

public ActionResult Upload(string qqfile)
{
    var stream = Request.InputStream;
    var buffer = new byte[stream.Length];
    stream.Read(buffer, 0, buffer.Length);

    var path = Server.MapPath("~/App_Data");
    var file = Path.Combine(path, qqfile);
    File.WriteAllBytes(file, buffer);

    // TODO: Return whatever the upload control expects as response
}

在这篇文章中回答:

MVC3 Valums Ajax文件上传

但问题是,这在IE中不起作用.我找到了这个,但我无法弄清楚如何实现它:

IE不会在"request.InputStream"中发送流...而是从Request.Files []集合中通过HttpPostedFileBase获取输入流

此外,这里显示了这个人是如何做到的,但我不知道如何改变我的项目:

Valum文件上传 - 适用于Chrome但不适用于IE,Image img = Image.FromStream(Request.InputStream)

//This works with IE
HttpPostedFileBase httpPostedFileBase = Request.Files[0]

作为HttpPostedFileBase;

无法想出这个.请帮忙!谢谢

Answer 1

我想到了.这适用于IE和Mozilla.

[HttpPost]
        public ActionResult FileUpload(string qqfile)
        {
            var path = @"C:\\Temp\\100\\";
            var file = string.Empty;

            try
            {
                var stream = Request.InputStream;
                if (String.IsNullOrEmpty(Request["qqfile"]))
                {
                    // IE
                    HttpPostedFileBase postedFile = Request.Files[0];
                    stream = postedFile.InputStream;
                    file = Path.Combine(path, System.IO.Path.GetFileName(Request.Files[0].FileName));
                }
                else
                {
                    //Webkit, Mozilla
                    file = Path.Combine(path, qqfile);
                }

                var buffer = new byte[stream.Length];
                stream.Read(buffer, 0, buffer.Length);
                System.IO.File.WriteAllBytes(file, buffer);
            }
            catch (Exception ex)
            {
                return Json(new { success = false, message = ex.Message }, "application/json");
            }

           return Json(new { success = true }, "text/html");
        }
