使用ASP.NET MVC区域路由找不到错误404 [英] Getting error 404 not found with ASP.NET MVC Area routing

问题描述

我在MVC 5中遇到了区域路由问题.当我浏览到/Evernote/EvernoteAuth时，出现404资源找不到错误.

I am having a problem with an Area route in MVC 5. When I browse to /Evernote/EvernoteAuth I get a 404 resource cannot be found error.

我的区域看起来像这样:

My area looks like this:

Areas
    Evernote
        Controllers
            EvernoteAuthController
        Views
            EvernoteAuth
                Index.cshtml

EvernoteAreaRegistration.cs(更新:未调用RegisterArea()，所以我进行了清理并重建".现在被调用，但结果相同.)包含以下路由图:

The EvernoteAreaRegistration.cs (UPDATE: RegisterArea() wasn't being called so I did a Clean and Rebuild. Now it is called but same result.) contains this route map:

public override void RegisterArea(AreaRegistrationContext context)
{
     context.MapRoute(
        "Evernote_default",
        "Evernote/{controller}/{action}/{id}",
        new { action = "Index", id = UrlParameter.Optional }
     );
}

EvernoteAuthController的Index()方法仅返回View().

The EvernoteAuthController's Index() method simply returns View().

我的应用程序的RouteConfig.cs当前未定义路由映射，但是我在此处尝试通过实现以下方式强制"使用它:

My application's RouteConfig.cs currently has no route maps defined, but I tried manually "forcing" it here by implementing this:

routes.MapRoute(
    name: "EvernoteAuthorization",
    url: "Evernote/{controller}/{action}",
    defaults: new { controller = "EvernoteAuth", action = "Index", id = UrlParameter.Optional },
    namespaces: new string[] { "AysncOAuth.Evernote.Simple.SampleMVC.Controllers" }
);

但是无论该路线图是否存在或被注释掉，我都得到相同的结果.

but I get the same results whether this route map exists or is commented out.

使用Phil Haack的 asp.net mvc路由调试器，我看到了我的路由很好，区域名称，控制器名称和操作方法名称也匹配.我在控制器操作方法中设置了断点，但从未输入这些方法.更新:浏览到/Evernote/EvernoteAuth时从未输入这些方法，但是当我仅浏览到区域名称/Evernote时，实例化了EvernoteAuthController并调用了Index()方法. (为什么控制器由/Evernote而不是/Evernote/EvernoteAuth实例化?)然后我收到错误消息:

Using Phil Haack's asp.net mvc routing debugger I saw that my routes matched fine and the area name, controller name and Action method names matched. I put breakpoints in the controller action methods and those methods were never entered. UPDATE: Those methods were never entered when browsing to /Evernote/EvernoteAuth however when I browsed to just the area name, /Evernote, an EvernoteAuthController was instantiated and the Index() method was called. (Why is that controller being instantiated by /Evernote by not by /Evernote/EvernoteAuth?) Then I received the error:

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

在这种情况下，我相信〜=/(应用程序根目录).因此未搜索区域Areas\Evernote\Views.

In this case I believe ~ = / (application root). So the area Areas\Evernote\Views is not being searched.

如何解决此问题?

推荐答案

将正确的名称空间添加到控制器很重要

It is important tha you add the correct namespace to your controller

  namespace YourDefaultNamespace.Areas.Evernote.Controllers
  {
    public class EvernoteAuthController : Controller
    { 
        ...
        ...
    }
  }

因此路由可以找到您的控制器. 现在，您必须使用方法

So the routing can find your controller. Now you have to register the area in the Global.asax.cs with the method

AreaRegistration.RegisterAllAreas();
