在 IIS7上运行时，如何将 maxAllowedContentLlength 设置为500MB？

我将 maxAllowedContentLlength 更改为

<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="5024000000" />
</requestFiltering>
</security>

在我的 web.config 中，但是当在 IIS7上运行时，我得到这个错误:

“ maxAllowedContentLlength”属性无效。不是有效的无符号整数

但是当我在 VS 服务器上运行时，它运行正常，没有任何错误。

如何配置我的网站，以允许上传文件的500 MB 大小，没有这个问题在 IIS7？

最佳答案

According to MSDN maxAllowedContentLength has type uint, its maximum value is 4,294,967,295 bytes = 3,99 gb

So it should work fine.

See also Request Limits article. Does IIS return one of these errors when the appropriate section is not configured at all?

The limit of requests in .Net can be configured from two properties together:

First

  • Web.Config/system.web/httpRuntime/maxRequestLength
  • Unit of measurement: kilobytes
  • Default value 4096 KB (4 MB)
  • Max. value 2147483647 KB (2 TB)

Second

  • Web.Config/system.webServer/security/requestFiltering/requestLimits/maxAllowedContentLength (in bytes)
  • Unit of measurement: bytes
  • Default value 30000000 bytes (28.6 MB)
  • Max. value 4294967295 bytes (4 GB)

References:

Example:

<location path="upl">
<system.web>
<!--The default size is 4096 kilobytes (4 MB). MaxValue is 2147483647 KB (2 TB)-->
<!-- 100 MB in kilobytes -->
<httpRuntime maxRequestLength="102400" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!--The default size is 30000000 bytes (28.6 MB). MaxValue is 4294967295 bytes (4 GB)-->
<!-- 100 MB in bytes -->
<requestLimits maxAllowedContentLength="104857600" />
</requestFiltering>
</security>
</system.webServer>
</location>

IIS v10 (but this should be the same also for IIS 7.x)

Quick addition for people which are looking for respective max values

Max for maxAllowedContentLength is: UInt32.MaxValue 🡒 4294967295 bytes : ~4GB

Max for maxRequestLength is: Int32.MaxValue 🡒 2147483647 bytes : ~2GB

web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.web>
<!-- ~ 2GB -->
<httpRuntime maxRequestLength="2147483647" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!-- ~ 4GB -->
<requestLimits maxAllowedContentLength="4294967295" />
</requestFiltering>
</security>
</system.webServer>
</configuration>
