主攻ASP.NET.3.5.MVC架构之重生:Controller(七)

<%:RouteData.Values["controller"].ToString()%>
//通过View的RouteData.Values对象取得当前所有路由值,并动态加载路由值中的Controller的名称

//Routing
//客户端请求->URL Routing ->Route->Route Handler->Http Handler

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//定义不需要通过Routing处理的网址
//IgnoreRoute辅助方法是ASP.NET MVC(System.Web.Mvc)

 routes.MapRoute(
                "Default", // 路由名称
                "{controller}/{action}/{id}", // 带有参数的 URL
                new { controller = "Test", action = "Index", id = UrlParameter.Optional } // 参数默认值
            );
//MapRoute辅助方法是ASP.NET MVC(System.Web.Mvc)

<%:RouteData.Values["controller"].ToString()%>
<%:RouteTable.Routes.GetVirtualPath(Request.RequestContext,new RouteValueDictionary(new {page=1})).VirtualPath %>
view:/?page=1
http://localhost:6782/Test/?page=1

//HandleUnknownAction  方法默认会响应"HTTP 404找不到资源"的错误信息
protected virtual void HandleUnknownAction(string actionName)
{
Response.Redirect("/");
}

 //[ActionName("Default")]动作选取器 只允许Default Action

 ///[NonAction]不对外公开属性

//把action public 改成private也可以达到同样效果 代码如下
------------------------------------------------------
        //[NonAction]
        private ActionResult Index()
        {
            return View();
        }
//跳转到另一个页面
------------------------------------------------------
        //[NonAction]
        [HttpPost]
        public ActionResult Index()
        {
            return new RedirectResult("/");
        }
//controller辅助方法,跳转到另一个页面 ,此方法多用
------------------------------------------------------
        [HttpPost]
        public ActionResult Index()
        {
            return Redirect("/");
        }
//指定index.apsx页面显示  Redirect不会跳转
------------------------------------------------------
        [HttpPost]
        public ActionResult Index()
        {
            return Redirect("/");
        }

        public ActionResult About()
        {
            return View("Index");
        }
//EmptyResult不会执行任何响应客户端的程序，所以也不返回任何数据，不需要视图
------------------------------------------------------
        public ActionResult Empty()
        {
            return new EmptyResult();
        }

//EmptyResult改写，这样简单
--------------------------------------------------
        public void Empty()
        {
            return;
        }
//EmptyResult不会执行任何响应客户端的程序，所以也不返回任何数据，不需要视图
------------------------------------------------------
        public ActionResult Empty()
        {
            return new EmptyResult();
        }

//301——删除请求数据
//302——在其他地址发现了请求数据
        //Response.Redirect()方法  HTTP302暂时转向
------------------------------------------------------
        public void Redirect()
        {
            Response.Redirect("/vipuser/login");
        }
//Asp.net 4.0新增Response.RedirectPermanent()建立HTTP301永久转向
------------------------------------------------------
        public void Redirect()
        {
            Response.RedirectPermanent("/vipuser/login");
        }
//响应xml content
------------------------------------------------------

        public ActionResult Content()
        {
            return Content("<Root><Text>context</Text></Root>", "text/xml", Encoding.UTF8);
