Where to define Routing

Static  Routing

Demo:https://www.iaspnetcore.com/robots.txt

step 1. Routing to controller actions

// contact us
endpoints.MapControllerRoute("ContactUs",
    "contact-us",
    new { controller = "Page", action = "ContactUs" });

// pages
endpoints.MapControllerRoute("Page",
    "{sename}",
    new { controller = "Page", action = "Detail" });

// for dynamic pages
endpoints.MapDynamicControllerRoute<PageRouteTransformer>("{sename}");

step 2: move to a class

namespace Microsoft.AspNetCore.Builder
{
    public static class RegisterRoutes3
    {

        /// <summary>
        /// 注册静态路由
        /// </summary>
        /// <param name="routes"></param>
        public static void MapModuleRoute3(this IEndpointRouteBuilder endpointRouteBuilder)
        {
            

            //endpointRouteBuilder.MapControllerRoute(name, pattern,
            //    new { controller = "Topic", action = "TopicDetails" });



            //robots.txt
            endpointRouteBuilder.MapControllerRoute("robots.txt", "robots.txt",
                new { controller = "Common", action = "RobotsTextFile" });

        }
    }
}

Step 3:Add to route table

 app.UseEndpoints(endpoints =>
            {
                var pattern = "{SeName}";

                endpoints.MapDynamicControllerRoute<SlugRouteTransformer>(pattern);

                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");

                endpoints.MapControllerRoute(name: "mobile-page-html5",
                pattern: "mobile-page-html5",
                defaults: new { controller = "MobileHtml5", action = "index" });

                endpoints.MapControllerRoute(name: "mobile-page-bootstrap",
                pattern: "mobile-page-bootstrap",
                defaults: new { controller = "MobileBootstrap5", action = "index" });

                endpoints.MapControllerRoute(
                            name: "areas",
                            pattern: "{area}/{controller}/{did?}/{action=Index}/{id?}");



                endpoints.MapModuleRoute3(); //static Routing
            });

Attribute Routing

public class MobileBootstrap5Controller : Controller
    {
        // GET: MobleBootstrap5Controller
        public ActionResult Index()
        {
            return View();
        }

        [Route("mobile-page-bootstrap-step1")]
        public ActionResult IndexStep1()
        {
            return View();
        }

        [Route("mobile-page-bootstrap-step2")]
        public ActionResult IndexStep2()
        {
            return View();
        }

        [Route("mobile-page-bootstrap-step3")]
        public ActionResult IndexStep3()
        {
            return View();
        }

        [Route("mobile-page-bootstrap-step4")]
        public ActionResult IndexStep4()
        {
            return View();
        }
