如何路由GET和DELETE请求相同的URL，以不同的控制器方法 [英] How to route GET and DELETE requests for the same url to different controller methods

问题描述

下面是我的路线在Global.asax中

  routes.MapRoute（PizzaGet，比萨/ {} pizzaKey，新{控制器=比萨，行动=GetPizzaById}）;
    routes.MapRoute（DeletePizza，比萨/ {} pizzaKey，新{控制器=比萨，行动=DeletePizza}）;
 

下面是我的控制器方法

 的[AcceptVerbs（HttpVerbs.Get）
公众的ActionResult GetPizzaById（长pizzaKey）的[AcceptVerbs（HttpVerbs.Delete）
公众的ActionResult DeletePizza（长pizzaKey）
 

当我这样做是返回对象的GET，但是当我做了删除，我收到了404。看起来这应该工作，但事实并非如此。

如果我切换围绕两条路线，然后我可以做删除，但得到的得到404

现在，这是真正的美丽。谢谢

  routes.MapRoute（比萨-GET，比萨/ {} pizzaKey
              新{控制器=比萨，行动=GetPizza}，
              新{列举HTTPMethod =新HttpMethodConstraint（新的String [] {GET}）}）;            routes.MapRoute（比萨-UPDATE，比萨/ {} pizzaKey
              新{控制器=比萨，行动=UpdatePizza}，
              新{列举HTTPMethod =新HttpMethodConstraint（新的String [] {PUT}）}）;            routes.MapRoute（比萨 - 删除，比萨/ {} pizzaKey
              新{控制器=比萨，行动=DeletePizza}，
              新{列举HTTPMethod =新HttpMethodConstraint（新的String [] {删除}）}）;            routes.MapRoute（比萨-ADD，比萨/
              新{控制器=比萨，行动=AddPizza}，
              新{列举HTTPMethod =新HttpMethodConstraint（新的String [] {POST}）}）;
 

解决方案

您可以通过类似这样的HTTP动词限制你的路线：

 的String [] = allowedMethods {GET，POST};
  VAR methodConstraints =新HttpMethodConstraint（allowedMethods）;  路线reportRoute =新干线（比萨/ {} pizzaKey，新MvcRouteHandler（））;
  reportRoute.Constraints =新RouteValueDictionary {{列举HTTPMethod，methodConstraints}};    routes.Add（reportRoute）;
 

现在你可以有两条路线，他们将在动词的制约。

Here are my routes in Global.asax

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

Here are the my controller methods

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

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

When I do a GET it returns the object, but when I do a DELETE I get a 404. It seems like this should work, but it doesn't.

If I switch the two routes around then I can do the DELETE, but get a 404 on the GET.

Now this is truly beautiful. Thanks

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" }) });

解决方案

You can constrain your routes by HTTP verb like this:

  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);

Now you can have both routes, and they will be constrained by the verbs.
