使用 Slug 的 C# Mvc 通用路由

Question

我正在尝试创建一个通用路由来处理 slug，但我总是遇到错误

我的想法是，我在 url 中得到一个友好的 www.site.com/{slug} 而不是 www.site.com/controller/action

例如www.site.com/Home/Open 将改为 www.site.com/open-your-company

错误

server error in '/' application The Resource cannot be found

在我的 Global.asax 我有

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

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

在我的一个 cshtml 中，我有以下链接(即使它被评论，仍然有同样的错误)。

@Html.ActionLink("Open your company", "DefaultSlug", new { controller = "Home", action = "Open", slug = "open-your-company" })

编辑:家庭 Controller

public ActionResult Open() { 
    return View(new HomeModel()); 
}

在 Global.asax 中你的 slug 不能为空，如果为空，url 将不会转到默认路由

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

    routes.MapRoute(
        name: "DefaultSlug",
        url: "{slug}",
        defaults: new { controller = "Home", action = "Open" },
        constraints: new{ slug=".+"});

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

并更新 HomeController

public ActionResult Open(string slug) {
    HomeModel model = contentRepository.GetBySlug(slug);

    return View(model); 
}

测试路线链接...

@Html.RouteLink("Open your company", routeName: "DefaultSlug", routeValues: new { controller = "Home", action = "Open", slug = "open-your-company" })

和操作链接...

@Html.ActionLink("Open your company", "Open", routeValues: new { controller = "Home", action = "Open", slug = "open-your-company" })

两者都产生...

http://localhost:35979/open-your-company
