mvc 重定向的几种方式

在RouteConfig添加一个简单的路由

            //新增路由
            routes.MapRoute(
                 name: "Article",
                 url: "Detial/{id}",
                 defaults: new { controller = "Article", action = "Detial", id = UrlParameter.Optional },
                 constraints: new { id = @"d+" }
                 //namespaces: new string[] { }
            );

302重定向

        public ActionResult UrlTest1()
        {//302
            return Redirect("/Article/Detial/1");
        }
        public ActionResult UrlTest2()
        {//302
            return RedirectToAction("Detial", "Article", new System.Web.Routing.RouteValueDictionary(new { id = 2 }));
            //return RedirectToAction("Detial", "Article",new { id  = 1});
        }
        public ActionResult UrlTest3()
        {//302
            return RedirectToRoute("Article", new System.Web.Routing.RouteValueDictionary(new { id = 3 }));
            //return RedirectToRoute("Article", new { id = 1 });
        }

301重定向

        public ActionResult UrlTest4()
        {//301
            return RedirectPermanent("/Article/Detial/4");
        }

        public ActionResult UrlTest5()
        {//301
            return RedirectToActionPermanent("Detial", "Article", new System.Web.Routing.RouteValueDictionary(new { id = 5 }));
            //return RedirectToActionPermanent("Detial", "Article", new { id = 1 });
        }

        public ActionResult UrlTest6()
        {//301
            return RedirectToRoutePermanent("Article", new System.Web.Routing.RouteValueDictionary(new { id = 6 }));
            //return RedirectToRoutePermanent("Article", new { id = 1 });
        }

也可以自己设置

        public ActionResult UrlTest7()
        {//可设置
            return new RedirectToRouteResult("Article", new System.Web.Routing.RouteValueDictionary(new { id = 7 }), false) { };
        }
        public ActionResult UrlTest8()
        {//可设置
            return new RedirectResult("/Article/Detial/8", false);
        }

要注意的是,在View()中指定不同的视图不是重定向

        public ActionResult UrlTest9()
        {//200
            return View("Detial", null, new { id = 9 });
        }

第二个代码段和第三个代码段中的方法,都会用第四个代码段中的形式最后以Response.Redirect方法返回给客户端
