簡約路線：沒有HTTP資源發現，請求URI

Question

我有我的WebApiConfig 2個簡單的路由匹配：

config.Routes.MapHttpRoute(
name: "Speaker", 
routeTemplate: "api/presentations/{presentationid}/speakers/{id}", 
defaults: new { controller = "speakers", id = RouteParameter.Optional } 
); 

config.Routes.MapHttpRoute(
name: "Presentations", 
routeTemplate: "api/presentations/{id}", 
defaults: new { controller = "presentations", id = RouteParameter.Optional } 
);
