asp.net-mvc – Asp.net Web api异常仅在IIS部署之后：名为“HelpPage_Default

我已经阅读了 this的问题,并尝试了在那里提到的解决方案,但是我收到这个异常,只有当我将应用程序发布到远程服务器的IIS.在本地计算机的IIS中,应用程序正常工作.我不知道在该服务器上导致此异常的原因：

Server Error in '/' Application.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34212

这是我在Global.asax.cs中设置的：

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            GlobalConfiguration.Configure(WebApiConfig.Register);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }

我的RouteConfig.cs：

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

和我的WebApiConfig.cs：

config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",routeTemplate: "api/{controller}/{id}",defaults: new { id = RouteParameter.Optional }
    );

我也对我的web.config文件进行了以下更改：

<system.webServer>
    <modules>
      <remove name="WebDAVModule" />
    </modules>
    <handlers>
      <remove name="WebDAV" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
  </system.webServer>

解决方法

为了解决这个问题,我在Visual Studio发布到我的Azure站点时勾选了“删除目的地的其他文件”框.我会假设你可以手动删除任何旧的文件在服务器上发布之前.之后,网站运行良好,没有错误.
