.NET MVC3无法通过FileUpload上传大文件

Question

我需要一种在我的.net mvc3网站(托管在亚马逊上)上传大文件(50+ MB)的方法.尝试上传大型zip文件(36.9MB)后,FireFox显示"连接已重置"屏幕,FireBug在状态下显示"已中止".

关于如何解决它的任何想法？

控制器:

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

Web.config文件:

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

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

Answer 1

该maxAllowedContentLength属性是以字节为单位:

<requestLimits maxAllowedContentLength= "10485760"/>

10485760字节= 10MB.因此,如果您尝试上传大于10MB的文件,则会失败.

maxRequestLength在KB 之间保持一致:

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

这表示限制为55MB和你的requestLimits.像这样:

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