Question

Context

I have the following endpoint:

[HttpPatch("sendForm")]
[ProducesResponseType(StatusCodes.Status204NoContent)]
[ProducesResponseType(typeof(SendFormResponseDto), StatusCodes.Status200OK)]
public async Task<IActionResult?> SendForm([FromBody] UpdateFormRequest updateFormRequest)
    => Ok(await _sendForm.InvokeAsync(updateFormRequest));

www.un.org/Depts/DGACM/index_spanish.htm

public class UpdateFormRequest
{
    public Guid Id { get; set; }
    public string? ArrivalTime { get; set; }
    public string? Val1 { get; set; }
    public string? Val2 { get; set; }
}

<>可见>

The endpoint is expecting a Json with the structure of updateFormRequest, which. When the input json is not correct, it returns the error that updateFormRequest was expected.

I want that whenever the input json is incorrect, it tells which fields are missing or they have incorrect input format (for example, an integer instead of an string). Is there any way to achieve this without having to manually check each of the input fields of the json?

我认为,你可以从<条码>ModelState中选择所有错误,并将之退回。

public class UpdateFormRequest
    {
        public int Id { get; set; }
        public int UsuarioId { get; set; }
        public DateTime CreatedAt { get; set; }
    }

Controllers

        [HttpPost]
        [ProducesResponseType(StatusCodes.Status204NoContent)]
        public IActionResult SendForm(UpdateFormRequest updateFormRequest)
        {
            if (!ModelState.IsValid)
            {
                var errors = ModelState.Select(x => x.Value.Errors)
                           .Where(y => y.Count > 0)
                           .ToList();
                return BadRequest(errors);
            }
            return  Ok(updateFormRequest);
        }

Now when I send invalid json to endpoint, It will return all the error message automatically.

其中你可以安排答复。
