ASP.NET MVC4 Web ZDB974238714CA8DE634A7CE1D08 中的 URL 路由

Question

這是我第一次在 ASP.NET 中編程 Web。 我正在嘗試在 WebApiConfig.cs 每種方法上設置 URL 路由。 但是具有相同參數類型的方法顯示404錯誤根據WebApiConfig.cs中的寄存器順序。 即使在方法上方設置了操作名稱，也會出現此問題。 為什么根據寄存器function的位置找不到url路徑？ 我也很好奇 WebApiConfig.cs 和 RouteConfig.cs 的區別。 感謝您閱讀長篇文章。

• WebApiConfig.cs

   public static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "Post", routeTemplate: "api/{controller}/{action}", defaults: new { controller = "ASSET", action = "Post" } ); config.Routes.MapHttpRoute( name: "InsertData", routeTemplate: "api/{controller}/{action}", defaults: new { controller = "ASSET", action = "InsertData" } ); config.Routes.MapHttpRoute( name: "RoadEmp", routeTemplate: "api/{controller}/{action}", defaults: new { controller = "ASSET", action = "RoadEmp" } ); config.Routes.MapHttpRoute( name: "SelectData", routeTemplate: "api/{controller}/{action}", defaults: new { controller = "ASSET", action = "SelectData" } ); config.Routes.MapHttpRoute( name: "RoadDept", routeTemplate: "api/{controller}/{action}", defaults: new { controller = "ASSET", action = "RoadDept" } ); config.Routes.MapHttpRoute( name: "Test", routeTemplate: "api/{controller}/{action}/{id}", defaults: new { controller = "ASSET", action = "Test" } );

Answer 1

您不需要WebApiConfig中的所有特定路由。

您可以將其保留為默認值：

config.Routes.MapHttpRoute(
   name: "api",
   routeTemplate: "api/{controller}/{action}/{id}",
   defaults: new { id = RouteParameter.Optional }
);

這應該使Post()和RoadDept()工作。

對於其他方法，例如public HttpResponseMessage SelectData(HttpRequestMessage manage_no)您不應該接受HttpRequestMessage作為參數。

您應該接受這些值（或 dto）。

這是ASP.NET Web API 2 中的屬性路由示例：

[Route("customers/{customerId}/orders")]
public IEnumerable<Order> GetOrdersByCustomer(int customerId) { ... }

這是另一個例子：

[HttpPost]
[Route("products")]
public IActionResult Action3([FromBody] Product product)
{
   // Validate product

   var id = product.Id;
   ...
}

此外，您顯示的方法是 POST，而不是 get，我建議嘗試使用不接受任何參數的 GET 方法並首先確認它是否有效。
