JQUERY ajax将JSON发送到C# MVC控制器，但是传入的数据为空。

$.ajax({
    url: '/YourController/YourAction',
    type: 'POST',
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    data: JSON.stringify({ key: 'value' }), // 确保这里的 JSON 数据格式正确
    success: function (response) {
        console.log('Success:', response);
    },
    error: function (xhr, status, error) {
        console.error('Error:', error);
    }
});

public class YourController : Controller
{
    [HttpPost]
    public ActionResult YourAction([FromBody] YourModel model)
    {
        if (model == null)
        {
            return Json(new { success = false, message = "Data is empty" });
        }

        // 处理接收到的数据...

        return Json(new { success = true, message = "Data received" });
    }
}

public class YourModel
{
    public string Key { get; set; }
}
