file size upload limitation in ASP.NET MVC: more than 1 maxRequestLength setting in web.config(s)
提问by Alex42
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).
我想为 maxRequestLength 设置 1 个以上 - 文件大小上传限制（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）。
Single setting works as expected:
单一设置按预期工作：
<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.
我试图在根 web.config 中有 2 个位置部分的 2 个设置，但没有任何成功。我不确定在“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>
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...
我试图将另一个 web.config 放在特定的视图文件夹中（例如 /Views/Picture/...），就像它在经典的 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>
No matter what I do, only one value for httpRuntime.maxRequestLength is applied - that in (root) web.config...system.web.
无论我做什么，都只应用了 httpRuntime.maxRequestLength 的一个值 - 在（根）web.config...system.web 中。

I believe the Path attribute shouldn't start or end with a "/" - so you should have:
我相信 Path 属性不应该以“/”开头或结尾——所以你应该有：
<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.
您的虚拟或物理目录级别的 Web.config 不应包含 <location> 元素。
That should sort you out.
那应该可以解决您的问题。
The docs for the Location elementeven have this very example:
Location 元素的文档甚至有这个例子：
The following code example demonstrates how to set the uploaded file size limit to 128 KB for only the page specified.
以下代码示例演示了如何仅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>
