如何将对同一URL的GET和DELETE请求路由到不同的控制器方法

Question

这是我在Global.asax中的路线

    routes.MapRoute("PizzaGet", "pizza/{pizzaKey}", new { controller = "Pizza", action = "GetPizzaById" });
    routes.MapRoute("DeletePizza", "pizza/{pizzaKey}", new { controller = "Pizza", action = "DeletePizza" });    

这是我的控制器方法

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GetPizzaById(long pizzaKey)

[AcceptVerbs(HttpVerbs.Delete)]
public ActionResult DeletePizza(long pizzaKey)

当我做一个GET它返回对象,但当我做一个删除我得到一个404.看起来这应该工作,但事实并非如此.

如果我切换两条路线然后我可以做DELETE,但在GET上获得404.

现在这真的很美.谢谢

routes.MapRoute("Pizza-GET","pizza/{pizzaKey}",
              new { controller = "Pizza", action = "GetPizza"},
              new { httpMethod = new HttpMethodConstraint(new string[]{"GET"})});

            routes.MapRoute("Pizza-UPDATE", "pizza/{pizzaKey}",
              new { controller = "Pizza", action = "UpdatePizza" },
              new { httpMethod = new HttpMethodConstraint(new string[] { "PUT" }) });

            routes.MapRoute("Pizza-DELETE", "pizza/{pizzaKey}",
              new { controller = "Pizza", action = "DeletePizza" },
              new { httpMethod = new HttpMethodConstraint(new string[] { "DELETE" }) });

            routes.MapRoute("Pizza-ADD", "pizza/",
              new { controller = "Pizza", action = "AddPizza" },
              new { httpMethod = new HttpMethodConstraint(new string[] { "POST" }) });

Answer 1

您可以通过HTTP动词约束您的路由,如下所示:

  string[] allowedMethods = { "GET", "POST" };
  var methodConstraints = new HttpMethodConstraint(allowedMethods);

  Route reportRoute = new Route("pizza/{pizzaKey}", new MvcRouteHandler());
  reportRoute.Constraints = new RouteValueDictionary { { "httpMethod", methodConstraints } };

    routes.Add(reportRoute);

现在你可以拥有两条路线,并且它们将受到动词的约束.

Answer 2

[ActionName("Pizza"), HttpPost]
public ActionResult Pizza_Post(int theParameter) { }

[ActionName("Pizza"), HttpGet]
public ActionResult Pizza_Get(int theParameter) { }

[ActionName("Pizza"), HttpHut]
public ActionResult Pizza_Hut(int theParameter) { }
