Resolve routes by named parameters - asp.net-core

Question

I have ASP Core 2.2 app. I defined controller:
using Microsoft.AspNetCore.Mvc;
namespace Web.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class UsersController : ControllerBase
{
[HttpGet]
public IActionResult Get()
{
return Ok();
}
[HttpGet("{id}")]
public IActionResult GetById(int id)
{
return Ok();
}
}
}
When I request with url /api/users/3 everything works fine, method GetById is called. But if I try to request /api/users?id=3 method Get is called and I don't know how to fix that. Moreover I would like to create two similar method different only by parameter name. For example public IActionResult GetById(int id) and public IActionResult GetByAge(int age) so I need strict routing by named parameters if possible. I don't want to implement custom middleware to resolve routes myself I wanna try to find ASP feature for that.

Answer 1

The url /api/users/3 : "3" is used as part of the route value .
The url /api/users?id=3: "3" is used as a query string in the url .
Attribute routing with Http[Verb] attributes is the value of which is part of the route value
You could change the Route attribute above the controller to specify action name like below :
[Route("api/[controller]/[action]")]
[ApiController]
public class UsersController : ControllerBase
{
// Get api/users/get
[HttpGet]
public IActionResult Get()
{
return Ok();
}
//Get api/users/GetById/3
[HttpGet("{id}")]
public IActionResult GetById(int id)
{
return Ok();
}
}
