Я пытаюсь использовать TempData в ядре asp.net. Однако я получаю нулевое значение в методе get TempData. Может кто-нибудь, пожалуйста, дайте мне знать, как я могу использовать TempData в ядре asp.net
Ниже перечислены вещи, которые я добавил в ходе исследования.

Вот реализация tempdata.When этот метод вызывается, я могу видеть значение в TempData.
[HttpGet("{pageNumber}")]
public GenericResponseObject<List<MarketViewModel>> GetMarketList(int pageNumber)
{
TempData["Currentpage"] = pageNumber;
TempData.Keep("Currentpage");
GenericResponseObject<List<MarketViewModel>> genericResponseObject = new GenericResponseObject<List<MarketViewModel>>();
genericResponseObject.IsSuccess = false;
genericResponseObject.Message = ConstaintStingValue.Tag_ConnectionFailed;
try
{
var marketItem = _iMarketUow.GetMarketList(pageNumber);
genericResponseObject.Data = marketItem.Item1;
var totalPages = (int)Math.Ceiling((decimal)marketItem.Item2 / (decimal)10);
genericResponseObject.TotalPage = totalPages;
genericResponseObject.IsSuccess = true;
genericResponseObject.Message = ConstaintStingValue.Tag_SuccessMessageRecord;
genericResponseObject.Message = ConstaintStingValue.Tag_ConnectionSuccess;
}
catch (Exception exception)
{
genericResponseObject.IsSuccess = false;
genericResponseObject.Message = exception.Message;
genericResponseObject.ErrorCode = exception.HResult;
genericResponseObject.ExceptionErrorMessage = exception.StackTrace;
}
return genericResponseObject;
}
Но метод ниже имеет нулевое значение в данных temp.
[HttpPost]
public GenericResponseObject<List<MarketViewModel>> AddUpdateMarket([FromBody] MarketViewModel marketViewModel)
{
GenericResponseObject<List<MarketViewModel>> genericResponseObject = new GenericResponseObject<List<MarketViewModel>>();
genericResponseObject.IsSuccess = false;
genericResponseObject.Message = ConstaintStingValue.Tag_ConnectionFailed;
if (marketViewModel!= null && ModelState.IsValid)
{
try
{
_iMarketUow.AddUpdateMarketList(marketViewModel);
genericResponseObject = GetMarketList(Convert.ToInt16(TempData.Peek("Currentpage")));
}
catch (Exception exception)
{
genericResponseObject.IsSuccess = false;
genericResponseObject.Message = exception.Message;
genericResponseObject.ErrorCode = exception.HResult;
genericResponseObject.ExceptionErrorMessage = exception.StackTrace;
}
}
else
{
genericResponseObject.Message = ConstaintStingValue.Tag_InputDataFormatNotMatch;
}
return genericResponseObject;
}
Вот образ сеанса отладки
