.NET MVC3无法通过文件上传上传大文件 [英] .NET MVC3 Can't upload large files via FileUpload

问题描述

我需要一种方法来在我的.NET MVC3网站（托管在亚马逊）上传大文件（50 + MB）。在尝试上载一个大的zip文件（36.9MB）FireFox中显示连接被重置屏幕，萤火显示中止状态下。

这是我怎么能解决这个问题的任何想法？

控制器：

 私人无效SAVEFILE（HttpPostedFileBase UploadedFile的）
{
    使用（var文件= System.IO.File.Create（使用Server.Mappath（/上传/+ uploadedFile.FileName））
        uploadedFile.InputStream.CopyTo（文件）;
}
 

Web.config文件：

 ＆LT;的System.Web＆GT;
    ＆LT;的httpRuntime maxRequestLength的=56320executionTimeout =1500/＆GT;
＆LT; /system.web>

  ＆LT; system.webServer＆GT;
    ＆LT;安全＆GT;
      ＆LT;的requestFiltering＆GT;
        ＆LT; requestLimits maxAllowedContentLength =10485760/＆GT;
      ＆LT; /的requestFiltering＆GT;
    ＆LT; /安全＆GT;
  ＆LT; /system.webServer>
 

解决方案

的<一个href="http://www.iis.net/ConfigReference/system.webServer/security/requestFiltering/requestLimits">maxAllowedContentLength属性是在字节：

 ＆LT; requestLimits maxAllowedContentLength =10485760/＆GT;
 

10485760字节= 10MB。所以，如果您尝试上传的文件是超过10MB你会失败更大。

做你 的maxRequestLength 这是KB：

 ＆LT;的System.Web＆GT;
    ＆LT;！ - 限制文件上传到55MB  - ＆GT;
    ＆LT;的httpRuntime maxRequestLength的=56320executionTimeout =1500/＆GT;
＆LT; /system.web>
 

这表明55MB和你的 requestLimits 的限制。像这样的：

 ＆LT; system.webServer＆GT;
    ＆LT;安全＆GT;
        ＆LT;的requestFiltering＆GT;
            ＆LT;！ - 限制文件上传到55MB  - ＆GT;
            ＆LT; requestLimits maxAllowedContentLength =57671680/＆GT;
        ＆LT; /的requestFiltering＆GT;
    ＆LT; /安全＆GT;
＆LT; /system.webServer>
 

I need a way to upload large files (50+ MB) in my .net mvc3 website (hosted on Amazon). After trying to upload a large zip file (36.9MB) FireFox shows "The connection was reset" screen and FireBug shows "Aborted" under status.

Any ideas on how I could solve it?

Controller:

private void SaveFile(HttpPostedFileBase uploadedFile)
{
    using (var file = System.IO.File.Create(Server.MapPath("/uploads/" + uploadedFile.FileName))
        uploadedFile.InputStream.CopyTo(file);
}

Web.config:

  <system.web>
    <httpRuntime maxRequestLength="56320" executionTimeout="1500"/>
</system.web>

  <system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxAllowedContentLength= "10485760"/>
      </requestFiltering>
    </security>
  </system.webServer>

解决方案

The maxAllowedContentLength property is in bytes:

<requestLimits maxAllowedContentLength= "10485760"/>

10485760 bytes = 10MB. So if you try to upload a file that is larger than 10MB you will fail.

Be consistent between your maxRequestLength which is in KB:

<system.web>
    <!-- Limit file uploads to 55MB -->
    <httpRuntime maxRequestLength="56320" executionTimeout="1500"/>
</system.web>

which indicates a limit of 55MB and your requestLimits. Like this:

<system.webServer>
    <security>
        <requestFiltering>
            <!-- Limit file uploads to 55MB -->
            <requestLimits maxAllowedContentLength="57671680"/>
        </requestFiltering>
    </security>
</system.webServer>
