Asp.net AJAX返回未定义、失败

我try 使用AJAX请求的Success和Failure块.我的函数正在工作，我可以很容易地直接指向控制器，并使用我的查询来修改我的SQL数据库，例如.一切正常，这就是我之前没有注意到AJAX响应的原因.

正如我所说的，我可以毫无问题地执行我的操作，但是我的AJAX总是返回失败，即使我的操作正在工作.我不明白怎么修，你能帮我看看吗？

error个

一开始，我试着把这个记录下来

console.log('Question sending failed:', result.message);

发送ProductDetail？ProductID=7:2879的问题 失败:未定义

然后我试着把这个记录下来

console.log('the entire result: ', result);

整个ProductDetail？ProductID=7:2880 结果:真

如果我同时记录这两个日志(log)，结果就是

整个ProductDetail？ProductID=7:2880 结果:真

您可以看到代码中的更改

action个

[HttpPost]
[Authorize]
public async Task<IActionResult> SendEmployeeQuestion(SetEmployeeQuestionQuery request)
{
    var result = await MediatrSend(request);
    return Json(result);
}

returns

对于"Return Json(Result)"，也是"true"

query个

public class SetEmployeeQuestionQuery : IRequest<bool>
    {
        public ClaimModel ClaimModel { get; set; }
        public int ProductId { get; set; }
        public int FirmId { get; set; }
        public string QuestionText { get; set; }
    }

    public class SetEmployeeQuestionQueryHandler : IRequestHandler<SetEmployeeQuestionQuery, bool>
    {
        private readonly IECommerceProductRepository _eCommerceProductRepository;
        public SetEmployeeQuestionQueryHandler(IECommerceProductRepository eCommerceProductRepository)
        {
            _eCommerceProductRepository = eCommerceProductRepository;
        }
        public async Task<bool> Handle(SetEmployeeQuestionQuery request, CancellationToken cancellationToken)
        {
            DateTime currentDateTime = DateTime.Now;
            string formattedTimestamp = currentDateTime.ToString("yyyy-MM-dd HH:mm:ss.fff");

            var questionId = _eCommerceProductRepository.InsertToEmployeeQuestion(request.ClaimModel.EmployeeId, formattedTimestamp).Result;

            await _eCommerceProductRepository.InsertToAnswerLog(null, questionId, request.FirmId, request.QuestionText, null);

            return true;
        }
    }
