asp.net Mvc 動態建立Controller

標籤：prot   路由規則   getc   ted   nbsp   pat   value   bbb   optional   

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產生Controller的，為了實現這樣的需求，通過尋找資料，可以重寫DefaultControllerFactory實現。步驟和代碼如下：

1、建立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，替換為FolderController            if (controllerType == null)            {                // 用路由欄位動態構建路由變數                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、建立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註冊自訂的FolderControllerFactory

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

5、在Views下建立一些檔案夾和View作為測試，

 

測試結果如下：

 

這樣就簡單的實現了通過博主的需求。。
