MVC RouteConfig，路由确定的控制器

Question

我只想通过 {action}{id} 访问我的主要页面（索引、关于、联系...），但通过 {controller}{action}{id} 访问其他页面。例如：

A principal page: myweb.com/index
No principal page: myweb.com/Account/Login

我已经搜索过，但我不知道具体是怎么做的。

这是我的路由配置

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

        /*routes.MapRoute(
            "Account",
        "Account/{AccountId}",
        new { action = "Index", controller = "Course" }
        );*/

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

        /*routes.MapRoute(
        "Account",
        "Account/{courseId}",
            //new { action = "Index", controller = "Course" }
        new { controller = "Home", action = "Index" }
        );*/
        //routes.Add()
    }
}

Answer 1

如下更改您的路由配置，但您必须将所有主要操作都放在一个控制器中，比如 PrincipalController，因为您的路由中不会有控制器。

始终在低优先级路由之前映射高优先级路由。

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Principal",
            url: "{action}/{id}",
            defaults: new { controller = Princpal", action = "Index", id = UrlParameter.Optional }

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

请看例子：

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        // Principal pages have unique route per each page.
        // Methods About and Contact should be implemented in HomeController.
        routes.MapRoute(
            name: "About",
            url: "about",
            defaults: new { controller = "Home", action = "About" }
        );

        routes.MapRoute(
            name: "Contact",
            url: "contact",
            defaults: new { controller = "Home", action = "Contact" }
        );

        // other pages use this default route
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
