Question

在RoutingConfig.cs中，我添加了以下代码来处理ASP.NET Web API中的处理HTTP 404错误

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(
            name: "Error404",
            routeTemplate: "{*url}",
            defaults: new { controller = "Error", action = "Handle404" }
        );
    }
}

它会抛出以下错误，如

＆＃39; System.Web.Routing.RouteCollection＆＃39;不包含的定义＆＃39; MapHttpRoute＆＃39;没有扩展方法＆＃39; MapHttpRoute＆＃39;接受一个类型＆＃39; System.Web.Routing.RouteCollection＆＃39;的第一个参数可能发现（您是否缺少using指令或程序集引用？）

我试图对名称空间System.Web.Routing.RouteCollection进行处理，但它无效

Answer 1

使用以下

//Catch-All InValid (NotFound) Routes
routes.MapRoute(
    name: "Error404",
    url: "{*url}",
    defaults: new { controller = "Error", action = "Handle404" }
);

确保这是要映射的最后一条路线，因为这是一条全能路线。

Answer 2

因为the following URI does not match, because it lacks the "api" segment.

RouteTemplate已配置为路由传入请求。

＆＃39; System.Web.Routing.RouteCollection＆＃39;不包含＆＃39; MapHttpRoute＆＃39;
