部署时提供404的MVC 4应用程序 [英] MVC 4 application giving a 404 when deployed

问题描述

我有一个使用.NET 4.5的ASP.NET MVC 4项目，我正在尝试使用Visual Studio 2012将其发布到IIS 7.0.当我在IIS Express中调试应用程序时，一切运行都很好.当我将其发布到服务器时，MVC请求返回404.我在站点上有几个aspx页面，它们都可以正常工作.以下是我的路由方案.这是样板代码:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

谢谢.

我明白了！我必须在web.config的system.webServer中添加以下内容:

<modules runAllManagedModulesForAllRequests="true"/>

有人可以告诉我为什么吗?

解决方案

此参考资料可能会有所帮助:

https://www.iis.net/configreference/system.webserver/modules

以前必须将runAllManagedModulesForAllRequests设置为true以支持路由.但是，使用Service Pack更新IIS 7后，可以在使用ASP.NET路由时将runAllManagedModulesForAllRequests的值设置为false或省略."/p>

(显然，首先要仔细考虑安装IIS或Windows Service Pack)

I have an ASP.NET MVC 4 project using .NET 4.5 that I am trying to publish to IIS 7.0 using Visual Studio 2012. When I debug the application in IIS Express everything works wonderfully. When I publish it to the server, the MVC requests return 404. I have a few aspx pages on the site and they all work fine. Below is my routing scheme. It is boilerplate code:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

Thanks.

Edits:

I got it! I had to add the following to system.webServer in my web.config:

<modules runAllManagedModulesForAllRequests="true"/>

Can anyone tell me why this is?

解决方案

This reference may help:

https://www.iis.net/configreference/system.webserver/modules

"runAllManagedModulesForAllRequests previously had to be set to true to support routing. However, once IIS 7 has been updated with a Service Pack, the value of runAllManagedModulesForAllRequests can be set to false or omitted when working with ASP.NET routing."

(obviously installing an IIS or Windows service pack needs careful consideration first)
