Question

I’m working on my first web api and I’m stuck trying to create rules for these urls

1) http://mydomain.com/values/4 --> this number can be any, this is just an example
2) http://mydomain.com/values/
3) http://mydomain.com/values/?param1=test1&param2=test2
4) http://mydomain.com/values/?param1=test1
5) http://mydomain.com/values/?param2=test2

My current routing rules are

routes.MapHttpRoute(
    name: "Route1",
    routeTemplate: "{controller}/{id}/"
);
routes.MapHttpRoute(
    name: "Route2",
    routeTemplate: "{controller}/{param1}/{param2}",
    defaults: new { param1 = RouteParameter.Optional, param2 = RouteParameter.Optional }
);

And my methods serving these urls

// GET values/
// GET values/?param1=test1&param2=test2
// GET values/?param1=test1
// GET values/?param2=test2
public IEnumerable Get(string param1, string param2)
{
    return new string[] { "value1", "value2" };
}

// GET values/5
public string Get(int id)
{
    return "value";
}

I have 2 problems

1) http://mydomain.com/values/ is not resolving

2) http://mydomain.com/values/?param1=test1 and http://mydomain.com/values/?param2=test2 are not resolving.

Could you help me to create routes for serving these urls?

Answer 1

routes.MapHttpRoute(
    name: "Route1",
    routeTemplate: "{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

Should do what you need. Query string parameters are already mapped to Action parameters as long as they are named the same, no need to add them in the route.
