asp.net Mvc 動態創建Controller

有這麼個需求，Urls如下：

http://localhost:52804

http://localhost:52804/home/test  

http://localhost:52804/test1

http://localhost:52804/test1/aaa

http://localhost:52804/test1/bbb

http://localhost:52804/test2/aaa

http://localhost:52804/test2/bbb

第1和2條url是代表真實存在Controller的，後面的都是需要動態生成Controller的，爲了實現這樣的需求，通過查找資料，可以重寫DefaultControllerFactory實現。步驟和代碼如下：

1、新建FolderControllerFactory.cs繼承自DefaultControllerFactory

 public class FolderControllerFactory : DefaultControllerFactory
    {
        public override IController CreateController(RequestContext requestContext, string controllerName)
        {
            var controllerType = GetControllerType(requestContext, controllerName);
            // 如果controller不存在，替換爲FolderController
            if (controllerType == null)
            {
                // 用路由字段動態構建路由變量
                var dynamicRoute = string.Join("/", requestContext.RouteData.Values.Values);
                controllerName = "Folder";
                controllerType = GetControllerType(requestContext, controllerName);
                requestContext.RouteData.Values["Controller"] = controllerName;
                requestContext.RouteData.Values["action"] = "Index";
                requestContext.RouteData.Values["dynamicRoute"] = dynamicRoute;
            }            
            IController controller = GetControllerInstance(requestContext,controllerType);
            return controller;
        }
    }

2、新建FolderController

public class FolderController : Controller
    {
        // GET: Folder
        public ActionResult Index(string dynamicRoute)
        {            
            string viewFile = "/Views/" + dynamicRoute + ".cshtml";
            return View(viewFile);
        }
    }

3、修改路由規則

 public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
            routes.MapRoute(
                "CatchAll",
                "{*dynamicRoute}",
                new { controller = "Folder", action = "Index" }
            );
        }

4、在Global.asax註冊自定義的FolderControllerFactory

protected void Application_Start()
        {
            ControllerBuilder.Current.SetControllerFactory(new FolderControllerFactory());
            AreaRegistration.RegisterAllAreas();            
            RouteConfig.RegisterRoutes(RouteTable.Routes);
        }

5、在Views下新建一些文件夾和View作爲測試，如圖：

 

測試結果如下：

 

這樣就簡單的實現了通過博主的需求。。
