컨트롤러 메소드의 매개변수로 직접 받기:

[HttpPost]
public IActionResult CreateBoard([FromBody] JObject data)
{
    // data 객체에서 필요한 값을 추출하여 사용할 수 있습니다.
    var div = data["data"]["div"].ToString();
    var m_group = data["data"]["m_group"].ToString();
    var m_id = data["data"]["m_id"].ToString();
    var title = data["data"]["title"].ToString();

    // 추출한 값들을 활용하여 원하는 동작 수행

    return Ok();
}

컨트롤러 메소드의 매개변수로 직접 받기2:

[HttpPost]

컨트롤러 메소드의 매개변수로 직접 모델 객체 받기:

        public class BoardModel
        {
            public int idx { get; set; }
            public string? div { get; set; }
            public string? m_group { get; set; }
            public string? m_id { get; set; }
            public string? title { get; set; }
        }
[HttpPost]
public IActionResult CreateBoard([FromBody] BoardModel board)
{
    // board 객체를 활용하여 필요한 값들을 사용할 수 있습니다.
    var div = board.div;
    var m_group = board.m_group;
    var m_id = board.m_id;
    var title = board.title;

    // 추출한 값들을 활용하여 원하는 동작 수행
            try
            {
                // Log or print jsonData to inspect the received data
                //Console.WriteLine($"Received JSON Data: {boardData}");

                // Your existing logic...
