int
タイプ入力とstring
タイプ入力の場合は、最初にHTTP GETリクエストを処理するための2つの方法があります。
_//GET : api/Fighters/5
[HttpGet("{id}")]
public async Task<ActionResult<Fighter>> GetFighter(int id)
{
var fighter = await _context.Fighters.FindAsync(id);
if (fighter == null)
{
return NotFound();
}
return fighter;
}
// GET: api/Fighters/Alex
[Route("api/Fighters/{name}")]
[HttpGet("{name}")]
public async Task<ActionResult<IEnumerable<Fighter>>> GetFighter (string name)
{
return await _context.Fighters.Where(f => f.Name == name).ToListAsync();
}

hTTPを送信するとこの例外が表示されます(Postman)。

_GET api/fighters/1
1
_ "がint
またはstring
のいずれかである可能性があるため、明らかにエラーが発生しますので、2つのメソッドを組み合わせることで問題を解決しました。
_// GET: api/Fighters/5
// GET: api/Fighters/Alex
[HttpGet("{idOrName}")]
public async Task<ActionResult<IEnumerable<Fighter>>> GetFighter(string idOrName)
{
if (Int32.TryParse(idOrName, out int id))
{
return await _context.Fighters.Where(f => f.Id == id).ToListAsync();
}
else
{
return await _context.Fighters.Where(f => f.Name == idOrName).ToListAsync();
}
}

しかし、これはまったく気分が良くない。この問題を処理するための適切な方法は何ですか?
.NET CORE 3.1以上のソリューションに従って、[route( "routename")]を使用してください。
[HttpPost]
[Route("CreateUserRole")]
// [Authorize(Roles = "admin")]
[ProducesResponseType(StatusCodes.Status201Created)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
[ProducesResponseType(StatusCodes.Status500InternalServerError)]

return BadRequest(ModelState);
}
if (!ModelState.IsValid)
