ASP.NET Web API属性路由

Question

API

[RoutePrefix("api/diagnostics")]
public class DiagnosticsController : ApiController
{
    [HttpPost]
    [Route("pings")]
    public IHttpActionResult Pings(Ping ping)
    {

    }
}

平

public class Ping
{
   public Guid ServerKey {get;set;}
   public DateTime CreatedDateTime {get;set;}
}

我正在尝试使用Postman应用程序测试该类。 这是截图 。

我收到的消息是：

{
"message": "No HTTP resource was found that matches the request URI 'http://localhost:61668/api/diagnostics/pings'.",
"messageDetail": "No action was found on the controller 'Diagnostics' that matches the request."
}

我无法理解为什么它与Diagnostics控制器中的发布操作不匹配 。 唯一配置的其他路由是默认路由：

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

还启用了属性路由：config.MapHttpAttributeRoutes（）;

尝试使用[FromBody]属性标记参数[FromBody] public IHttpActionResult Pings([FromBody] Ping ping) 。
