asp.net Mvc 動態創建Controller

字段 control == return 註冊 gis nor factory request
有這麽個需求,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,為了實現這樣的需求,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,替換為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作為測試,如圖:
測試結果如下:
這樣就簡單的實現了通過博主的需求。。
