ASP.NET MVC HTTP Post/Delete

Question

我有一個ASP.NET MVC應用程序。 我有單一的函數模式，這將被稱爲與HTTP POST和HTTP DELETE。

雖然調用Post，但絕不會調用Delete。我確認IIS接受HTTP刪除。任何意見？

路線和控制器：

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

我不知道該HTTP支持刪除。無論如何，只需使用信息進行刪除操作即可。只要你不使用GET來執行DELETE動作，你就很好。下面是一些參考...

Answer 2

從上面的代碼中，我認爲有圖案{version}/cards/{cardID}任何URL將被「RegisterCard」路線，不管動詞是什麼處理（後/刪除）。對於「刪除」，將選擇「註冊卡」路線，然後當[HttpPost]動作選擇器進場時，它將導致404錯誤。如果您遇到404 「刪除」，你可能會

ONE 添加約束路線

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" }) } 
); 

或使一個單一的路徑與單一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，將它們合併

希望這有助於。
