ASP MVC Route Config - 无法找到资源错误 [英] ASP MVC Route Config - The resource cannot be found error

问题描述

我是asp mvc的新手，目前，我的演示项目结构如下：

I'm newbie in asp mvc, currently, my demo project structure like this:

Areas -- Comment -- Controller -- HomeController
                               -- ManageController

Controller -- HomeController
          |-- CommentController
                     |____ PostMsg
                     |____ DeleteMsg
Views -- Home
     |     |--- Index.cshtml
     |-- Comment
           |--- PostMsg.cshtml
           |--- DeleteMsg.cshtml

当我浏览网址时：

When I browsing url like :

http://localhost/Comment/Manage/ --> return view successfully
http://localhost/Comment/PostMsg --> error "The resource cannot be found."

任何人都知道为什么asp mvc无法解析我的控制器： - （

这是我的global.asax.cs路由配置：

Anyone have any idea why asp mvc doesn't resolve my controller :-(
here is my global.asax.cs route config:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    
                routes.MapRoute(
                    name: "Default",
                    url: "{controller}/{action}/{id}",
                    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                    namespaces: new[] { "Demo.Web.Controllers" }
                );

这里是我的区域注册路线配置：

here is my area registration route config:

public override void RegisterArea(AreaRegistrationContext context)
            {
                context.MapRoute(
                    "Comment_default",
                    "Comment/{controller}/{action}/{id}",
                    new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                    new[] { "Demo.Web.Areas.Comment.Controllers" }
                );
            }

问题：评论/ PostMsg网址在评论区域被解析为控制器



目标：评论/ PostMsg网址被解决为CommentController的行动

任何帮助将不胜感激:-)



ISSUE RESOLVED ，编辑区域注册路线配置（解决方法）：

Problem : Comment/PostMsg url was resolved as an Controller in Comment Area

Goal : Comment/PostMsg url was resolved as an Action of CommentController
Any help would be appreciated :-)

ISSUE RESOLVED, edit area registration route config (work around):

public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                "Comment_default",
                "Comment/PostMsg",
                new { controller = "Comment", action = "PostMsg", id = UrlParameter.Optional },
                new[] { "Demo.Web.Controllers" }
            );

            context.MapRoute(
                "Comment_default",
                "Comment/{controller}/{action}/{id}",
                new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                new[] { "Demo.Web.Areas.Comment.Controllers" }
            );
        }

推荐答案

这是我的示例代码正常工作

this is my example code thats work properly

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

            routes.MapRoute(
     "viewstudent", // Route name
     "view/viewstudent/{stdid}", // URL with parameters
     new { controller = "Movie", action = "SelectById", id = UrlParameter.Optional } // Parameter defaults
     );

            routes.MapRoute(
       "Default", // Route name
       "{controller}/{action}/{id}", // URL with parameters
       new { controller = "Home", action = "Index", id = UrlParameter.Optional }// Parameter defaults
);
                
    
        }

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RegisterRoutes(RouteTable.Routes);
         
        RouteDebug.RouteDebugger.RewriteRoutesForTesting(RouteTable.Routes);  
        
        }

编辑区域注册路线配置（解决方法）：

Edit area registration route config (work around):

public override void RegisterArea(AreaRegistrationContext context)
        {
            context.MapRoute(
                "Comment_default",
                "Comment/PostMsg",
                new { controller = "Comment", action = "PostMsg", id = UrlParameter.Optional },
                new[] { "Demo.Web.Controllers" }
            );
 
            context.MapRoute(
                "Comment_default",
                "Comment/{controller}/{action}/{id}",
                new { controller = "Home", action = "Index", id = UrlParameter.Optional },
                new[] { "Demo.Web.Areas.Comment.Controllers" }
            );
        }

转到Web项目的属性页面，然后选择Web选项卡。在开始操作部分中，将其设置为特定页面，但将文本框保留为空。

Go to the properties page of the Web project and select the Web tab. In the Start Action section, set it to Specific Page, but leave the textbox empty.
