ASP MVC 路由配置 - 找不到资源错误

Question

我是asp mvc的新手，目前我的demo项目结构如下：

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：

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 不能解析我的控制器 :-(

这是我的 global.asax.cs 路由配置：

            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" }
            );

这是我的区域注册路线配置：

        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 url 被解析为评论区的控制器

Goal : Comment/PostMsg url 被解析为 CommentController 的 Action

任何帮助将不胜感激:-)

问题已解决，编辑区域注册路线配置（解决方法）：

        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" }
            );
        }

Answer 1

您在 Demo.Web.Areas.Comment.Controllers 的 **PostMsgController 中有操作 Index ** 吗？据我了解你没有

更新 1

从您的代码中我认为 /Comment/PostMsg - 可能是您在 Demo.Web.Areas.Comment.Controllers 中的控制器 PostMsgController 的操作索引

更新 2

比你应该做的

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