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)
    {

    }
}

Ping

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

我正在尝试使用 Postman 应用程序测试课程。这是Screenshot。

我收到的信息是：

{
"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."
}

我不明白为什么它与诊断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] 属性标记您的参数 - public IHttpActionResult Pings([FromBody] Ping ping)。
