routing - 路由中的多个 Controller

Question

我可能有一个蹩脚的问题，但我在一个 Url 中路由多个 Controller 时遇到了一些困难。所以我的问题是如何使用这样的网址:

GET http://foo.com/API/Devices/2/Parameters/2

最终在哪里device和 parameters都是 Controller ，数字是 ID。我每个人都有 Controller ，但是如何处理它们，将它们路由到适当的 Controller ？

有什么方向可以看吗？

更新:
只是为了澄清我最终使用的解决方案并遵循以下答案。

路由片段:

config.Routes.MapHttpRoute(
            name: "DeviceCommandsControllerHttpRoute", 
            routeTemplate: "api/devices/{deviceId}/commands/{id}", 
            defaults: new { controller = "devicecommands", id = RouteParameter.Optional }
        );

Controller 片段:

[HttpGet]
public DeviceCommand GetById(int id, int deviceId)
    { ... }

最后是网址:

GET http://localhost:49479/api/Devices/2/Commands/1

我现在有类似的需求，我有以下路由结构:

public static void RegisterRoutes(HttpRouteCollection routes) {

    routes.MapHttpRoute(
        "UserRolesHttpRoute",
        "api/users/{key}/roles",
        new { controller = "UserRoles" });

    routes.MapHttpRoute(
        "AffiliateShipmentsHttpRoute",
        "api/affiliates/{key}/shipments",
        new { controller = "AffiliateShipments" });

    routes.MapHttpRoute(
        "ShipmentStatesHttpRoute",
        "api/shipments/{key}/shipmentstates",
        new { controller = "ShipmentStates" });

    routes.MapHttpRoute(
        "AffiliateShipmentShipmentStatesHttpRoute",
        "api/affiliates/{key}/shipments/{shipmentKey}/shipmentstates",
        new { controller = "AffiliateShipmentShipmentStates" });

    routes.MapHttpRoute(
        "DefaultHttpRoute",
        "api/{controller}/{key}",
        new { key = RouteParameter.Optional });
}

我认为您可以基于此弄清楚如何实现您的。
