asp.net-mvc - 将 ASP.NET MVC 路由迁移到 ASP.NET vNext

Question

我有一个 ASP.NET MVC 应用程序。我正在学习 ASP.NET vNext。为此，我决定将现有应用程序移植到 vNext。我不确定的是，如何移植我的路线。

在我的原始 ASP.NET MVC 应用程序中，我有以下内容:

RouteConfig.cs

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

  routes.MapRoute(
    name: "Index",
    url: "",
    defaults: new { controller = "Root", action = "Index" }
  );

  routes.MapRoute(
    name: "Items",
    url: "items/{resource}",
    defaults: new { controller = "Root", action = "Items", resource = UrlParameter.Optional }
  );

  routes.MapRoute(
    name: "BitcoinIntegration",
    url: "items/available/today/{location}",
    defaults: new { controller="Root", action="Availability", location=UrlParameter.Optional }
  );

  routes.MapRoute(
    name: "BlogPost1",
    url: "about/blog/the-title",
    defaults: new { controller = "Root", action = "BlogPost1" }
  );
}

现在在这个 ASP.NET vNext 世界中，我不知道如何设置路由。我有以下内容:

Startup.cs

using Microsoft.AspNet.Builder;
using Microsoft.AspNet.Routing;
using Microsoft.Framework.DependencyInjection;

namespace MyProject.Web
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app)
        {
            app.UseErrorPage();

            app.UseServices(services =>
            {
                services.AddMvc();
            });

            app.UseMvc(routes =>
            {
                routes.MapRoute("areaRoute", "{area:exists}/{controller}/{action}");
            });

            app.UseMvc();
            app.UseWelcomePage();
        }
    }
}

不过，我不确定两件事:

1. 如何添加我之前在 RouteConfig.cs 中定义的路由。
2. 如何使用 views/home/Index.cshtml 作为我的默认路径来代替 app.UseWelcomePage()。

注册路线:有一些变化，但总体方法保持不变。这是您重构的 RouteConfig:

RouteConfig.cs

using Microsoft.AspNet.Builder;
using Microsoft.AspNet.Routing;

public class RouteConfig 
{
  // instead of RouteCollection, use IRouteBuilder
  public static void RegisterRoutes(IRouteBuilder routes)
  {
    // routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); -> gone
    // routes.RouteExistingFiles = true; -> gone

    routes.MapRoute(
      name: "Index", 
      template: "", 
      defaults: new { controller = "Root", action = "Index" }
    );

    // instead of UrlParameter.Optional, you use the ? in the template to indicate an optional parameter
    routes.MapRoute(
      name: "Items", 
      template: "items/{resource?}", 
      defaults: new { controller = "Root", action = "Items" }
    );

    ... // ignored for brevity (since their registration is along the same lines as the above two).
  }
}

Startup.cs

public void Configure(IApplicationBuilder app)
{
  // ... other startup code
  
  app.UseMvc(RouteConfig.RegisterRoutes);  
  
  // ... other startup code
}

注意:您可以在此处很好地内联路由注册，但我更喜欢将其放在单独的文件中以消除困惑 Startup.cs
