Why list of object is null in query parameters-CodePudding

I'am trying to get list of object from query parameter but it's null.

I Added [FromQuery] before it but it's still null

Controller :

[HttpGet("filter")]
public async Task<IActionResult> GetFilteredSperms([FromQuery] List<SpermFilterDTO> filters, [FromQuery] string name)
    {
        var result = await _mediator.Send(new GetSpermsByFilterQuery { Filters = filters });

        foreach (var item in filters)
        {
            Console.WriteLine($"Index is {item.Index}");
        }

        Console.WriteLine($"Name is {name}");

        return Ok(result);
    }

name property is Ok but filters is empty.

CodePudding user response：

It is not recommended (nor really supported) to place complex objects in the query string. A GET action supports a request body and a GET request with a body is not forbidden by any specification or standard.

Thus, moving the object from the query to the body will allow your action to function as intended.
