 @GetMapping("/topay")
    @ResponseBody
    public String toPay(HttpServletRequest request, @RequestParam("orderNo") String orderNo, HttpSession httpSession, @RequestParam("payType") int payType) throws Exception {
        NewBeeMallUserVO user = (NewBeeMallUserVO) httpSession.getAttribute(Constants.MALL_USER_SESSION_KEY);
        NewBeeMallOrder newBeeMallOrder = newBeeMallOrderService.getNewBeeMallOrderByOrderNo(orderNo);
        request.setAttribute("orderNo", orderNo);
        request.setAttribute("totalPrice", newBeeMallOrder.getTotalPrice());
        if (payType == 1) {
            String form = alipayService.toPay("商品购买", new BigDecimal(newBeeMallOrder.getTotalPrice()),orderNo);
            return form;
        } else {
            return "mall/wxpay";
        }
    }
