c# - 为什么这个 MVC 路由不起作用？

Question

我在 RouteConfig 类中定义了以下路由:

       routes.MapRoute(
             name: "DefaultMessage",
             url: "API/{action}",
             defaults: new { action = "MessageGateway" }
         ); 
        routes.MapRoute(
              name: "DefaultNoParms",
              url: "{controller}/{action}",
              defaults: new { controller = "API", action = "Login" }
         );

当我仅使用 localhost:65133/作为地址在我的本地主机上进行测试时，我被路由到 APIController 上的登录 ActionResult，但是当我尝试 localhost:65133/API 时，我收到以下错误:

The matched route does not include a 'controller' route value, which is required

谁能告诉我哪里出了问题？ ActionResult MessageGateway 确实存在...

似乎错误是不言自明的 - 您需要告诉它去哪个 Controller 。

routes.MapRoute(
    name: "DefaultMessage",
    url: "API/{action}",
    defaults: new { controller = "API", action = "MessageGateway" }
);
