QuestionASP.Net MVC Core API Question Revisited Pin
Kevin Marois18-Apr-24 19:44

I posted on this yesterday, but I haven't made any progress.

I'm just trying to set up a simplet test API. Here's my controller:
[Route("api/user")]
[ApiController]
public class UserController : _ControllerBase
{
    public UserController(IConfiguration configuration) :
        base(configuration)
    {
    }

    [HttpGet("getById/{id}")]
    public IActionResult GetById([FromQuery]int id)
    {
        try
        {
            var repo = new Repository(GetDataContext());

            var owner = repo.GetById(id);

            if (owner is null)
            {
                return NotFound();
            }
            else
            {
                return Ok(owner);
            }
        }
        catch (Exception ex)
        {
            return StatusCode(500, "Internal server error");
        }
    }

    [HttpGet]
    public IActionResult GetAll()
    {
        try
        {
            var repo = new Repository(GetDataContext());

            var owners = repo.GetAll();

            return Ok(owners);
        }
        catch (Exception ex)
        {
            return StatusCode(500, "Internal server error");
        }
    }

    [HttpPost]
    public IActionResult Test([FromBody]TestEntity testEntity)
    {
        return StatusCode(200);
    }
}
I can call the first two methods, GetAll and GetById like this:
https: //localhost:5001/api/User
and
https: //localhost:5001/api/User/GetById/1
and they both return data. But this gives me a Not Found error
[HttpPost]
public IActionResult Test([FromBody]TestEntity testEntity)
{
//...
}
called using Postman like this:
https: //localhost:5001/api/User/test/{"id": 10,"name": Someone Else}

Questions
First, I'm not even sure I have the controller methods set up right. I don't really understand when/why to use the various attributes such as [FromBody] & [FromQuery]. I'm slowly learning by I may have it wrong here.

If I'm passing an object, as opposed to say an int, what should the method signature look like? Do I use FromBody or FromQuery? My Google searches return many different results. What would the correct syntax look like?

Second, the way I'm passing params, seperated by '/' seems wrong. Shouldn't the call to the API look something like this?
https: //localhost:2001/api/User/GetById?id=123
Am I doing something wrong here?
In theory, theory and practice are the same. But in practice, they never are.”
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
