(這邊只先列出必要的參數，若想要想新增自訂欄位供User使用，都可再去擴充原本的class，先不在這邊做贅述。)

先來個pseudo code:

        [HttpPost("QueryPayOrder")]
        public async Task<ActionResult<OrderPayQueryReq>> QueryPayStatusAsync(OrderPayQueryReq orderInfo)
        {

            orderInfo = new OrderPayQueryReq()
            {
                //以下輸入為示意
                //ShopNo="NA0249_001",
                APIService = APIService.OrderPayQuery,
                //Sign = "A3EAEE3B361B7E7E9B0F6422B954ECA5D54CEC6EAB0880CB484AA6FDA4154331",
                //Message = "",
                //Nonce = "NjM2NjA0MzI4ODIyODguMzo3NzI0ZDg4ZmI5Nzc2YzQ1MTNhYzg2MTk3NDBlYTRhNGU0N2IxM2Q2M2JkMTIwOGU5YzZhMGFmNGY5MjA5YzVm",
                //PayToken = "",
            };
            try
            {
                OrderPayQueryReq result = await _orderService.PostQpayApiAsync(orderInfo, APIService.OrderPayQuery);
                return result;
            }
            catch (Exception e)
            {
                //throw e;
                return StatusCode(500);
            }
        }
