ASP.NET MVC HTTP Post/Delete

Question

我有一个ASP.NET MVC应用程序。 我有单一的函数模式，这将被称为与HTTP POST和HTTP DELETE。

虽然调用Post，但绝不会调用Delete。我确认IIS接受HTTP删除。任何意见？

路线和控制器：

routes.MapHttpRoute(
      name: "RegisterCard", 
      routeTemplate: "{version}/cards/{cardID}", 
      defaults: new { Controller = "MyController", Action = " 

      routes.MapHttpRoute(
      name: "UnregisterCard", 
      routeTemplate: "{version}/cards/{cardID}", 
      defaults: new { Controller = "MyController", Action = "Delete" });     




    [HttpPost] 
    public async Task<HttpResponseMessage> Post(string version, string cardID); 
    { 
    } 

    [HttpDelete] 
    public async Task<HttpResponseMessage> Delete(string version, string cardID); 
    { 
    } 

Answer 1

我不知道该HTTP支持删除。无论如何，只需使用信息进行删除操作即可。只要你不使用GET来执行DELETE动作，你就很好。下面是一些参考...

Answer 2

从上面的代码中，我认为有图案{version}/cards/{cardID}任何URL将被“RegisterCard”路线，不管动词是什么处理（后/删除）。对于“删除”，将选择“注册卡”路线，然后当[HttpPost]动作选择器进场时，它将导致404错误。如果您遇到404 “删除”，你可能会

ONE 添加约束路线

routes.MapHttpRoute(
    name: "RegisterCard", 
    routeTemplate: "{version}/cards/{cardID}", 
    defaults: new { Controller = "MyController", Action = "Post"}, 
    constraints: new { httpMethod = new HttpMethodConstraint(new[] { "post" }) } 
); 

routes.MapHttpRoute(
    name: "UnregisterCard", 
    routeTemplate: "{version}/cards/{cardID}", 
    defaults: new { Controller = "MyController", Action = "Delete" }, 
    constraints: new { httpMethod = new HttpMethodConstraint(new[] { "delete" }) } 
); 

或使一个单一的路径与单一ActionName

routes.MapHttpRoute(
    name: "Card", 
    routeTemplate: "{version}/cards/{cardID}", 
    defaults: new { Controller = "MyController", Action = "HandleCard"} 
); 

[ActionName("HandleCard")] 
[HttpPost] 
public async Task<HttpResponseMessage> Post(string version, string cardID); 
{ 
} 

[ActionName("HandleCard")] 
[HttpDelete] 
public async Task<HttpResponseMessage> Delete(string version, string cardID); 
{ 
} 

在一起，将它们合并

希望这有助于。
