c# - 如何在路由中定义 PUT 方法只限于 Controller 中的 Put 方法不带参数？

Question

这里是WebApiConfig.cs中的路由配置:

config.Routes.MapHttpRoute(
    name: "DefaultApiPut",
    routeTemplate: "api/{controller}",
    defaults: new { httpMethod = new HttpMethodConstraint(HttpMethod.Put) }
);


config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get, HttpMethod.Post, HttpMethod.Delete) }
);

这是我的 Controller :

public class MyController : ApiController {
    [HttpPut]
    public void Put()
    {
        //blah
    }
}

不知何故，当客户端发送带有 URL /api/myController/12345 的 PUT 请求时，它仍然映射到 MyController 中的 Put 方法>，我预计会出现类似资源未找到的错误。

如何强制Put方法只接受不带参数的请求？

提前致谢!

这可以限制路由上的 http 方法:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
    config.Routes.MapHttpRoute(
       name: "LocationApiPOST",
       routeTemplate: "api/{orgname}/{fleetname}/vehicle/location",
       defaults: new { controller = "location" }
       constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Post) }
   );

    config.Routes.MapHttpRoute(
       name: "LocationApiGET",
       routeTemplate: "api/{orgname}/{fleetname}/{vehiclename}/location/{start}",
       defaults: new { controller = "location", start = RouteParameter.Optional }
       constraints: new { httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
   );

   ...

}
