【发布时间】：2015-08-08 09:19:00
【问题描述】：

问题

当页面和路由存在时，404 Error on https://localhost:44300/services。

问题

是什么导致了这个路由问题？

注意观察

我无法理解的是 https://localhost:44300/ 和 https://localhost:44300/articles 之类的目录是如何工作的。

【问题讨论】：

您是否尝试过使用 RouteDebugger（nuget 包）来查看您期望被命中的路由是否是路由实际命中的路由？
我没有。我什至不知道这件事。我一直在使用 CodeMaid 和 Web Essentials。我一定会检查一下，看看它是否带来了什么。我最大的问题是在没有错误消息的情况下修复某些内容。
谢谢@KarenB！因为你，我得到了答案！

【解决方案1】：

如果您使用的是默认的 ASP.Net MVC 5 项目，那么这可能对您很有帮助。首先，RouteDebugger Nuget 包在上次更新 3 年后仍然是一个很棒的工具。它很容易指出我的错误。

Global.Asax

首先，注意AreaRegistration.RegisterAllAreas(); 是如何放在RouteConfig.RegisterRoutes(RouteTable.Routes); 之前的。路由按照接收到的路由配置的顺序优先。 AreaRegistration 优先于 RouteConfig。

RouteConfig.cs 和 ArticleAreaRegistration.cs

接下来，Article and Portfolio areas 使用的路由配置与

        // default route (last)
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

因此，由于 ArticleAreaRegistration 在前，因此这两个之后的服务路由将不起作用。
