use both url parameter and query string

Question

I have two action methods in my Products controller. This is my RouteConfig.

config.MapHttpAttributeRoutes();

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

These are the two actions and their working urls.

[HttpGet]
//uri:http://localhost:49964/api/products/product?strKey=1
public IHttpActionResult Product(string strKey)

[HttpPost]
//uri:http://localhost:49964/api/products/product
public IHttpActionResult Product([FromBody] Product product)

But I also want to use the below url for GET.

http://localhost:49964/api/products/product/1

But web api responds with,

The requested resource does not support http method 'GET'.

Change strKey to id or do the reverse if you want to keep strKey.

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

The route template needs to match up to the action for mapping to work as intended.

//GET api/products/product/1
//GET api/products/product?strKey=1
[HttpGet]    
public IHttpActionResult Product(string strKey)

this would however mean that all actions in this route would optionally use strKey as a placeholder
