c# - 使用 RouteConfig 更改路径后旧路径不起作用

Question

我正在使用 Entity Framework 开发 C# ASP.NET MVC 项目。

我正在尝试使用 RouteConfig.cs 更改 url 路径

首先代码是这样的

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
        );
    }
}

我想把 url localhost/Customer/Index 改成 localhost/Index

所以我添加了这行代码并且成功了

routes.MapRoute(
    name: "customer",
    url: "customer",
    defaults: new { controller = "Customer", action = "Index"}
);

接下来，我尝试将 localhost/Customer/Details/2 更改为 localhost/CustomerName/2。

// CustomerName varies with each customer

所以我加了这个

 routes.MapRoute(
     name: "customerDetail",
     url: "customer/{name}/{id}",
     defaults: new { controller = "Customer", action = "Details", id = UrlParameter.Optional, name = UrlParameter.Optional }
);

现在客户详细信息页面可以正确加载。

但是使用此路径加载索引页面 localhost/Customer/Index 会导致错误，而 localhost/Customer 不会导致错误。为什么会这样？

编辑

这就是我的 RouteConfig 的样子

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "customer",
            url: "customer",
            defaults: new { controller = "Customer", action = "Index"}
        );
        routes.MapRoute(
            name: "customerDetail",
            url: "customer/{name}/{id}",
            defaults: new { controller = "Customer", action = "Details", id = UrlParameter.Optional, name = UrlParameter.Optional }
        );

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
        );
    }
}

终于找到答案了。

As @StephenMuecke commented

localhost/Customer/Index matches the customerDetail route (and passes "Index" to the id parameter)

所以我重新检查了我的代码，发现 localhost/Customer/Details/2 中的 id 字段不是可选的，我不小心将它定义为可选的， id = UrlParameter.Optional.

 routes.MapRoute(
        name: "customerDetail",
        url: "customer/{name}/{id}",
        defaults: new { controller = "Customer", action = "Details", name = UrlParameter.Optional }
    );

完整的 RoutConfig 代码:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "customer",
            url: "customer",
            defaults: new { controller = "Customer", action = "Index"}
        );
        routes.MapRoute(
            name: "customerDetail",
            url: "customer/{name}/{id}",
            defaults: new { controller = "Customer", action = "Details",name = UrlParameter.Optional }
    );

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional }
        );

    }
}
