如何在命名空间中路由混合的 MvcApplication 和 WebApiApplication？

Question

我有一个带有两个控制器的 MVC 应用程序，一个用作 WebAPiApplication，第二个用作常规 MvCApplication。我已经以某种方式配置了只能访问 API 的路由。

你能帮我配置成我可以访问两个控制器的方式吗？

我可以通过指向 http://localhost/api/data 访问 API 的 DefaultController。但是，我无法访问 MvcApplication Index 方法。我的期望是通过指向 http://localhost/Notification 来访问它，但我收到错误 404 !

这是我的控制器 C# 源代码：

//DefaultController.cs    
namespace MyApp.Controllers
{
    [RoutePrefix("api")]
    public class DefaultController : ApiController
    {
        [Route("data")]
        [AcceptVerbs("GET")]
        public HttpResponseMessage GetMeData()
        {
             XYZ...
        }
    }
}

//NotificationController.cs    
namespace MyApp.Controllers
{
    public class NotificationController : Controller
    {    
        public ActionResult Index()
        {
            return this.Jsonp(Rep.All());
        }
    }
}

下面是我如何设置到这两个控制器的路由：

//Global.asax.cs
namespace MyApp
{
    public class WebApiApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }

    public class MvcApplication : System.Web.HttpApplication
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
        }

        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");    
            routes.MapRoute(
                "Notification", // Route name
                "{controller}/{action}", // URL with parameters
                new { controller = "Notification", action = "Index" } // Parameter defaults
            );
        }    
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();    
            RegisterGlobalFilters(GlobalFilters.Filters);
            RegisterRoutes(RouteTable.Routes);
        }
    }
}

//WebApiConfig.cs
namespace MyApp
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.MapHttpAttributeRoutes();   
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }
}

正如@ChimaOsuji 在评论中提到的，

You've created two applications, WebApiApplication and MvcApplication. You only need one, in which you register routes for both MVC and API controllers.

Global.asax.cs

namespace MyApp
{

    public class WebApplication : System.Web.HttpApplication
    {
        public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
        }

        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");    
            routes.MapRoute(
                "Notification", // Route name
                "{controller}/{action}", // URL with parameters
                new { controller = "Notification", action = "Index" } // Parameter defaults
            );
        }    
        protected void Application_Start()
        {
            //Web api config
            GlobalConfiguration.Configure(WebApiConfig.Register);
            //MVC config
            AreaRegistration.RegisterAllAreas();    
            RegisterGlobalFilters(GlobalFilters.Filters);
            RegisterRoutes(RouteTable.Routes);
        }
    }
}

只需将您的两个应用程序合并为一个：

public class WebApiApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        // this is the call to register your WebApi routes
        GlobalConfiguration.Configure(WebApiConfig.Register);

        // this is the call to register your MVC routes
        RouteConfig.RegisterRoutes(RouteTable.Routes);

        // register other components...
        AreaRegistration.RegisterAllAreas();    
        RegisterGlobalFilters(GlobalFilters.Filters);
    }
}
