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

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

Thnx. I thought that id in route template is a placeholder.

Nkosi Over a year ago

it is a place holder in the route template. it is just not a reserved one like controller, action or area

I think the docs have never stressed on that 'reserved' part anywhere. I used to believe it to be a reserved placeholder.
