     public ModelAndView pay(String orderNo, TransactionDTO transaction, @RequestParam("secretImg") List<String> secretImg, Integer payMethod) {
         ModelAndView mv = new ModelAndView();
         if (StringTool.isEmptyByTrim(orderNo) || transaction == null || payMethod == null || payMethod == PayMethod.PAYPAL) {
             mv.setViewName("");
             return mv;
         }
         transaction.setImgUrl(StringTool.list2Str(secretImg, "|"));
         orderService.payOrder(header(), orderNo, transaction, payMethod);
         mv.setViewName("redirect:/payment/payresult.cf?orderNo=" + orderNo);
