在 ASP.Net MVC 中定义自定义 URL 路由

Question

我定义了以下路线：

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

    routes.MapRoute(name: "Homepage", url: "", defaults: new { controller = "Restaurants", action = "Search" });
    routes.MapRoute(name: "About", url: "about", defaults: new { controller = "Home", action = "About" });
    routes.MapRoute(name: "Disclaimer", url: "disclaimer", defaults: new { controller = "Home", action = "Disclaimer" });
    routes.MapRoute(name: "Contact", url: "contact", defaults: new { controller = "Home", action = "Contact" });
    routes.MapRoute(name: "RestaurantDetails", url: "{id}/{slug}", defaults: new { controller = "Restaurant", action = "Details" });
    routes.MapRoute(name: "RestaurantLocationDetails", url: "{id}/{restaurantSlug}/{locationSlug}", defaults: new { controller = "Restaurant", action = "LocationDetails" });
    routes.MapRoute(name: "Api", url: "api/{action}", defaults: new { controller = "Api" });
}

我找到了一些给出 404 的路由，所以我安装了 RouteDebugger NuGet 包。

它显示了我对前 4 条路线的期望，但在最后 3 条路线上，我仍然得到 404 并且 Route Debugger 没有出现在页面底部 - 我希望它会告诉我哪些位得到了映射，但我什么也没得到。所有视图都存在。

所以我假设我在路线定义上犯了一个错误 - 任何人都可以对此有所了解吗？另外，如何让 Route Debugger 向我展示 URL 如何映射到那些返回 404 的页面的路由字典中？

您需要更改路线的顺序。

routes.MapRoute(name: "Homepage", url: "", defaults: new { controller = "Restaurants", action = "Search" });
routes.MapRoute(name: "About", url: "about", defaults: new { controller = "Home", action = "About" });
routes.MapRoute(name: "Disclaimer", url: "disclaimer", defaults: new { controller = "Home", action = "Disclaimer" });
routes.MapRoute(name: "Contact", url: "contact", defaults: new { controller = "Home", action = "Contact" });
routes.MapRoute(name: "Api", url: "api/{action}", defaults: new { controller = "Api" });
routes.MapRoute(name: "RestaurantLocationDetails", url: "{id}/{restaurantSlug}/{locationSlug}", defaults: new { controller = "Restaurant", action = "LocationDetails" });
routes.MapRoute(name: "RestaurantDetails", url: "{id}/{slug}", defaults: new { controller = "Restaurant", action = "Details" });

路由按照添加到路由列表的顺序进行处理。

例如：api/action 也匹配 RestaurantDetails 路由，因为路由 url 参数中只有两个参数。

所以它需要从具体到一般。通常，如果您在两个路由定义中具有相同数量的参数，则添加的第一个路由将是选择的那个。
