问题 I am new to using Ember and have been following an online video tutorial (see weblink below, though its dated as it uses .NET Core 1.0) that demonstrates how to setup a JSON API back-end with an Ember front-end - I am using Visual Studio Code.

问题 I'm building a system using ASP.NET Core 2.0 Razor Pages (not MVC) and I'm having trouble adding multiple routes for pages. For example, all pages should be able to be reached by abc.com/language/ segment /shop/mypage or abc.com/language/shop/mypage, where both paths point to the same page. The segment path section is optional, then the pages do stuff with the optional segment info.
