MVC4默认路由指向一个区域

Question

我的项目中有 2 个领域：

Areas | Admin
Areas | FrontEnd

我想要的是当我访问该站点时，默认路由应该从FrontEnd 区域加载控制器/视图/模型。将Url/Admin 用于管理面板是正常的，但我宁愿不必强制使用Url/FrontEnd（或其他一些变体）。基本上我不想在根级别使用 Controller / Model / View 文件夹。

我不确定如何更改代码以允许这样做，甚至这是一种可取的方法。有人可以提供一些指导吗？

我有什么：

routes.MapRoute(
                "Admin_default",
                "Admin/{controller}/{action}/{id}",
                new { 
                    area = "Admin",
                    controller = "Home", 
                    action = "Index", 
                    id = UrlParameter.Optional 
                },
                namespaces: new[] { "WebsiteEngine.Areas.Admin.Controllers" }
            );

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { 
                    area = "FrontEnd", 
                    controller = "Home", 
                    action = "Index", 
                    id = UrlParameter.Optional 
                },
                namespaces: new[] { "WebsiteEngine.Areas.FrontEnd.Controllers" }
            );

但是这会产生错误：

The view 'Index' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/Index.aspx
~/Views/Home/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
~/Views/Home/Index.cshtml
~/Views/Home/Index.vbhtml
~/Views/Shared/Index.cshtml
~/Views/Shared/Index.vbhtml

我确实在该区域有可用的视图，但这看起来不像在那里。

我相信你可以这样做：

// Areas/Admin/AdminAreaRegistration.cs
public class AdminAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get { return "Admin"; }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            name: "Admin_Default", 
            url: "Admin/{controller}/{action}/{id}", 
            defaults: new 
            {
                area = "Admin",
                controller = "Home", 
                action = "Index", 
                id = UrlParameter.Optional 
            });
    }
}


// Areas/Admin/FrontEndAreaRegistration.cs
public class FrontEndAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get { return "FrontEnd"; }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            name: "FrontEnd_Default", 
            url: "{controller}/{action}/{id}", 
            defaults: new 
            {
                area = "FrontEnd",
                controller = "Home", 
                action = "Index", 
                id = UrlParameter.Optional 
           });
    }
}

// Global.asax.cs
protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    ...
}

现在，在您的 RouteConfig 类中，您可能设置了 Default 路由。请记住，只要您调用AreaRegistration.RegisterAllAreas之前您调用RouteConfig.RegisterRoutes，您在区域中设置的路线可能会覆盖您在RouteConfig 中设置的路线。 （路由按照它们在Routes 集合中出现的顺序进行评估，.MapRoute 将新路由推到最后）
