MVC Valums阿贾克斯上传

本文介绍了MVC Valums阿贾克斯上传 - IE不request.InputStream发送流的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用Valums阿贾克斯上传。所有在Mozilla与此code的伟大工程：

查看：

VAR键= $（'＃文件上传'）[0];VAR上传=新qq.FileUploader（{    元素：按钮，    allowedExtensions：JPG，JPEG，PNG，GIF]    的sizeLimit：2147483647，//最大尺寸    动作：'/管理/主页/上传'，    多：假的}）;

控制器：

公众的ActionResult上传（字符串qqfile）{    VAR流= Request.InputStream;    VAR缓冲=新的字节[stream.Length]    stream.Read（缓冲液，0，buffer.Length）;    VAR路径=使用Server.Mappath（〜/ App_Data文件）;    var文件= Path.Combine（路径，qqfile）;    File.WriteAllBytes（文件，缓冲液）;    // TODO：返回无论上传控件预计为响应}

这是回答了在这个职位：

  

MVC3 Valums阿贾克斯文件上传

然而问题是，这并不工作在IE。我确实发现这一点，但我无法弄清楚如何实现它：

  

IE不发送数据流中  request.InputStream...而不是弄  通过输入流  HttpPostedFileBase从  Request.Files []集合

此外，这在这里显示这个家伙是怎么做到的，但我不知道如何为我的项目更改：

Valum文件上传 - 适用于Chrome，但不是IE，图片IMG = Image.FromStream（Request.InputStream）

//这适用于IE浏览器HttpPostedFileBase httpPostedFileBase = Request.Files [0]

    

作为HttpPostedFileBase;

想不通这一个。请帮忙！谢谢

解决方案

我想通了。这在IE和Mozilla。

[HttpPost]        公众的ActionResult文件上传（字符串qqfile）        {            VAR路径= @C：\\\\ \\\\温度100 \\\\;            var文件=的String.Empty;            尝试            {                VAR流= Request.InputStream;                如果（String.IsNullOrEmpty（请求[qqfile]））                {                    // IE                    HttpPostedFileBase postedFile = Request.Files [0];                    流= postedFile.InputStream;                    文件= Path.Combine（路径，System.IO.Path.GetFileName（Request.Files [0] .FileName））;                }                其他                {                    // Webkit内核，Mozilla的                    文件= Path.Combine（路径，qqfile）;                }                VAR缓冲=新的字节[stream.Length]                stream.Read（缓冲液，0，buffer.Length）;                System.IO.File.WriteAllBytes（文件，缓冲液）;            }            赶上（异常前）            {                返回JSON（新{成功= FALSE，消息= ex.Message}，应用/ JSON）;            }           返回JSON（新{成功= TRUE}，text / html的）;        }

i'm using Valums Ajax uploader. all works great in Mozilla with this code:

View:

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 });

Controller:

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 }

which was answered in this post:

MVC3 Valums Ajax File Upload

However issue is that this doesn't work in IE. I did find this but i can't figure out how to implement it:

IE doesn't send the stream in "request.InputStream" ... instead get the input stream through the HttpPostedFileBase from the Request.Files[] collection

Also, this here that shows how this guy did it but i'm not sure how to change for my project:

Valum file upload - Works in Chrome but not IE, Image img = Image.FromStream(Request.InputStream)

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

as HttpPostedFileBase;

can't figure this one out. please help! thanks

解决方案

I figured it out. This works in IE and 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"); }
