  routes.MapRoute(

              "Movie/{action}/{currPage}/{movieId}", // 带有参数的 URL
               new { controller = "Movie", action = "Index", currPage = 1, movieId = UrlParameter.Optional } // 参数默认值
          );

            routes.MapRoute(

            new { controller = "Movie", action = "Index", currPage = 1, movieId = UrlParameter.Optional } // 参数默认值
       );
