asp.net-mvc – 我想使用web.config中的规则在localhost portnum

<rule name="adding Id after PortNumber" patternSyntax="Wildcard" stopProcessing="true">
        <match  url="(.*)" />
        <conditions>
          <add input="{HTTP_HOST}" pattern="{HTTP_HOST}/12312312" negate="true"/>
        </conditions>
        <action type="Redirect" url="{HTTP_HOST}/{R:1}"/>
      </rule>

这是我的route.config

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

        routes.MapRoute(
           "ApplicationRoute","{appId}/{controller}/{action}/{id}",new { controller = "Account",action = "SignIn",id = UrlParameter.Optional },new {
               isValidAppId = new isValidAppId() 
           }
       );
    }
}

public class isValidAppId : IRouteConstraint
{
    public bool Match(HttpContextBase httpContext,Route route,string parameterName,RouteValueDictionary values,RouteDirection routeDirection)
    {
        var isValid = false;
        if (values["appId"] != null && WebConfigurationManager.AppSettings["ModelApplicationId"] != null)
        {
            if (values["appId"].ToString() == WebConfigurationManager.AppSettings["ModelApplicationId"].ToString())
                return isValid = true;
        }

        // return true if this is a valid AppId
        return isValid;
    }
}

但是,当我运行这个我得到的网址为’http://localhost:49363/‘,但我想’http://localhost:49363/12312312‘
