具有不同参数名称的多个参数的 MVC 路由

Question

在我的家庭控制器中，我有 3 个 Action 方法。这是下面给出的。

        public ActionResult Index(int id)
        {
            return View();
        }


        public ActionResult Index2(int did,int docType)
        {
            return View();
        }


        public ActionResult Index3(int uid,int docId,int typeId)
        {
            return View();
        }

因为我在每个操作方法中给出了不同的参数名称，所以我必须在 Route.config 中进行更改。

我已经做到了

方法一

routes.MapRoute(
                name: "Home",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Home",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

但它给了我例外，比如

Home' is already in the route collection. Route names must be unique

所以我改成了这样

方法二

 routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}/{did}/{docType}/{uid}/{docId}/{typeId}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional, did = UrlParameter.Optional, docType = UrlParameter.Optional, uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
        );

当我点击Url喜欢

http://localhost:50958/Home/Index/2

http://localhost:50958/Home/Index2/2/3

http://localhost:50958/Home/Index3/2/3/4

它向我抛出异常。

这是解决方案。

正如 Stephen Muecke 所建议的那样

 routes.MapRoute(
                name: "Admin",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "User",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

Answer 1

路由名称应该是唯一的，您有两条同名路由："Home"

Answer 2

因为我为所有路线指定了相同的名称。并且路由名称必须是唯一的，现在我已经用不同的名称重命名了路由。

routes.MapRoute(
                name: "Admin",
                url: "{controller}/{action}/{did}/{docType}",
                defaults: new { controller = "Home", action = "Index2", did = UrlParameter.Optional, docType = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "User",
                url: "{controller}/{action}/{uid}/{docId}/{typeId}",
                defaults: new { controller = "Home", action = "Index3", uid = UrlParameter.Optional, docId = UrlParameter.Optional, typeId = UrlParameter.Optional }
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
