ASP.NET Core Web API, Multiple Get or Post Methods with Single Controller

Why?

I was assigned a duty to develop a RESTful API for my company. And I was like, why not try out the new .NET Core. So I started an MVC Web API project. No surprise, it was similar to .NET 4.5+. Single Get or Post method for each controller. But I wanted a service controller with several get methods for customer.

Let's get to it.

Instead of modifying the webapiconfig, the Route options is directly in the controller class.

//
// Default generated controller
//

[Route("api/[controller]")
public class myApiController : Controller
{
    [HttpGet]
    public string GetInfo()
    {
        return "Information";
    }
}

//
//A little change would do the magic
//

[Route("api/{controller}/{action}")]
public class ServicesController : Controller
{
    [HttpGet]
    [ActionName("Get01")]
    public string Get01()
    {
        return "GET 1";
    }

    [HttpGet]
    [ActionName("Get02")]
    public string Get02()
    {
        return "Get 2";
    }
    
    [HttpPost]
    [ActionName("Post01")]
    public HttpResponseMessage Post01(MyCustomModel01 model)
    {
        if (!ModelState.IsValid)
            return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
        
        //.. DO Something ..
        return Request.CreateResonse(HttpStatusCode.OK, "Optional Message");
    }
    
    [HttpPost]
    [ActionName("Post02")]
    public HttpResponseMessage Post02(MyCustomModel02 model)
    {
        if (!ModelState.IsValid)
            return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
        
        //.. DO Something ..
        return Request.CreateResonse(HttpStatusCode.OK, "Optional Message");
    }


}

That's it. Hope this will help someone.
