在ASP.NET核心MVC中使用AJAX在模型中发布问题

public class Question
{
    public string Title { get; set; }
    public string Content { get; set; }
    public DateTime PublishTime { get; set; }

    public void Save()
    {
        // 将问题保存到数据库中的代码
        // 使用Entity Framework或其他ORM框架进行数据访问
    }
}

public class QuestionController : Controller
{
    [HttpPost]
    public IActionResult SaveQuestion(Question question)
    {
        question.PublishTime = DateTime.Now;
        question.Save();

        return Json(new { success = true });
    }
}

<form id="questionForm">
    <input type="text" name="Title" />
    <textarea name="Content"></textarea>
    <button type="submit">发布问题</button>
</form>

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
    $(function () {
        $('#questionForm').submit(function (e) {
            e.preventDefault();

            var formData = $(this).serialize();
            $.ajax({
                url: '/Question/SaveQuestion',
                type: 'POST',
                data: formData,
                success: function (response) {
                    if (response.success) {
                        alert('问题发布成功！');
                    } else {
                        alert('问题发布失败！');
                    }
                },
                error: function () {
                    alert('问题发布失败！');
                }
            });
        });
    });
