C# 使用HTTP模块时出错-检测到ASP.NET设置不适用于集成托管管道模式

我启动应用程序时出错

An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

我创建了一个HTTP模块，它从请求头读取信息并将数据写入cookie。这是代码

namespace My.Web
{
    public class UserIdModule : IHttpModule
    {
        private HttpApplication httpApp;

        public void Init(HttpApplication application)
        {
            application.BeginRequest += (new EventHandler(this.Application_BeginRequest));
        }


        private void Application_BeginRequest(Object source, EventArgs e)
        {
            // Create HttpApplication and HttpContext objects to access
            // request and response properties.
            HttpApplication application = (HttpApplication)source;
            HttpContext context = application.Context;

            //Read header
            string userId = context.Request.Headers["user_id"];

            if (string.IsNullOrEmpty(userId))
            {
                userId = "guest";
            }

            //Create and write cookie
            HttpCookie userCookie = new HttpCookie("userId", userId);
            userCookie.Expires = DateTime.Now.AddYears(5);  
            context.Response.Cookies.Add(userCookie);
        }

        public void Dispose() { }
    }
}

在my web.config中

<configuration>
  <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".*" mimeType="application/octet-stream" />
    </staticContent>
    <!-- To register the module for IIS 6.0 and IIS 7.0 running in Classic mode -->
    <modules>
      <add name="UserIdModule" type="UserIdModule"/>
    </modules>
  </system.webServer>
  <system.web>
    <compilation targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
    <!-- To register the module for IIS 7.0 running in Integrated mode -->
    <httpModules>
      <add name="UserIdModule" type="UserIdModule"/>
    </httpModules>
  </system.web>
</configuration>

这是错误的屏幕截图：

我认为您可能已经将集成模式和经典模式颠倒了-至少从您在配置文件中的注释来看是这样的

system.web用于旧的经典模式，system.webserver用于集成模式。参考如下

如果您在一个配置中有一些通常属于另一个的配置设置，我可以看到您出现此错误。

是IIS 7.5吗

<system.webServer>
    <modules>
       <add name="UserIdModule"  type="My.Web.UserIdModule"/>
    </modules>
</system.webServer>

检查这些，
