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个路径的期望,但是在最后3个路由中我仍然得到404并且alas Route Debugger没有出现在页面底部 - 我希望它能告诉我哪些位被映射,但是我一无所获.所有观点都存在.

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向我展示如何将URL映射到返回404的页面的路由字典？

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" });

路线按照添加到路线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,如果在两个路径定义中具有相同数量的参数,则添加的第一个路径将是所选择的路径.
