ASP.NET MVC 中的文件大小上传限制：web.config 中的 maxRequestLength 设置超过 1

我希望对 maxRequestLength - 文件大小上传限制有超过 1 个设置（例如，一个用于文件/新建，另一个用于图片/新建）。我的所有操作都采用附加参数（例如/File/New?folderId=234）。

单个设置按预期工作：

<httpRuntime executionTimeout="60" maxRequestLength="1024" />

我尝试在根 web.config 中使用 2 个位置部分进行 2 个设置，但没有成功。我不知道在“路径”中写什么 - 视图的物理 aspx 页面，或控制器+操作...但是，似乎没有任何效果。

<location path="/File/">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="4096" />
    </system.web>
</location>
<location path="/Picture/">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="1024" />
    </system.web>
</location>

我尝试将另一个 web.config 放在特定的视图文件夹中（例如 /Views/Picture/...），就像它在经典 Webform ASP.NET 中工作一样，但这似乎也不起作用...

<location path="">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="1024" />
    </system.web>
</location>

否无论我做什么，都只会应用 httpRuntime.maxRequestLength 的一个值 - 在（根）web.config...system.web 中。

I'd like to have more than 1 setting for maxRequestLength - file size upload limitation (e.g. one for File/New, other for Picture/New). All of my Actions take additional parameters (e.g. /File/New?folderId=234).

Single setting works as expected:

<httpRuntime executionTimeout="60" maxRequestLength="1024" />

I tried to have 2 settings with 2 location sections in the root web.config, but without any success. I'm not sure what to write in "path" - physical aspx page of a view, or controller+action... however, nothing seems to work.

<location path="/File/">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="4096" />
    </system.web>
</location>
<location path="/Picture/">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="1024" />
    </system.web>
</location>

I tried to put another web.config in a specific view folder (e.g. /Views/Picture/...), like it works in classic Webform ASP.NET, but this doesn't seem to do the trick either...

<location path="">
    <system.web>
        <httpRuntime executionTimeout="60" maxRequestLength="1024" />
    </system.web>
</location>

No matter what I do, only one value for httpRuntime.maxRequestLength is applied - that in (root) web.config...system.web.

我相信 Path 属性不应该以“/”开头或结尾 - 所以你应该：

<location path="File">
  <system.web>
    <httpRuntime executionTimeout="60" maxRequestLength="4096" />
  </system.web>
</location>
<location path="Picture">
  <system.web>
    <httpRuntime executionTimeout="60" maxRequestLength="1024" />
  </system.web>
</location>

你的虚拟或物理目录级 Web.config 不应该有。元素。

那应该可以解决你的问题。

Location 元素的文档甚至有这个例子：

以下代码示例演示如何将指定页面的上传文件大小限制设置为 128 KB。

<configuration>
  <location path="UploadPage.aspx">
    <system.web>
      <httpRuntime maxRequestLength="128"/>
    </system.web>
  </location>
</configuration>

I believe the Path attribute shouldn't start or end with a "/" - so you should have:

<location path="File">
  <system.web>
    <httpRuntime executionTimeout="60" maxRequestLength="4096" />
  </system.web>
</location>
<location path="Picture">
  <system.web>
    <httpRuntime executionTimeout="60" maxRequestLength="1024" />
  </system.web>
</location>

Your virtual or physical directory–level Web.config's shouldn't have the <location> elements.

That should sort you out.

The docs for the Location element even have this very example:

The following code example demonstrates how to set the uploaded file size limit to 128 KB for only the page specified.

<configuration>
  <location path="UploadPage.aspx">
    <system.web>
      <httpRuntime maxRequestLength="128"/>
    </system.web>
  </location>
</configuration>
