c# – Asp.net Web API属性路由404错误

这是我的设置：

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Attribute routing
        config.MapHttpAttributeRoutes();

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

    }
}

这是我的控制器与我的路由属性：

[Route("api/v1.0/orders")]
public class OrdersV1Controller
{

    [APIAuthentication(RequireAuthentication = true)]
    [HttpGet]
    [Route("{id:int}")]
    public GetOrderResponse GetOrder(int id)
    { 
      .....
    }
}

这是我的全局asax文件：

public class Global : HttpApplication
{
    void Application_Start(object sender,EventArgs e)
    {
        AreaRegistration.RegisterAllAreas();
        GlobalConfiguration.Configure(WebApiConfig.Register);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.DefaultValueHandling = Newtonsoft.Json.DefaultValueHandling.Populate;
    }
}

这是我正在测试的URL返回404未找到：

HTTP：//本地主机：60105 / API / 1.0 /命令/ 222221
