前端发送接收代码

let params = new URLSearchParams();params.append('outTradeNo', orderid);params.append('totalAmount', resp.data.sum);params.append('subject', resp.data.name);axios.post("http://127.0.0.1:7000/alipay/getPagePay", params).then(function (resp) {$("#div").html(resp.data.pay);//div盒子});

这是和网上大哥做的，但是容易出现钓鱼网站的问题

第一种解决办法是删除缓存和更换浏览器，但还是要看脸

第二种解决办法（我也没用过，老师教的）：

//设置请求参数 AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest(); //同步回调，如果本地调度只会走同步，这里的界面就是你付款后跳转的界面 alipayRequest.setReturnUrl(AlipayConfig.return_url); //异步回调，没有服务器实际上我们用不到 alipayRequest.setNotifyUrl(AlipayConfig.notify_url); //订单名称，必填 String subject=request.getParameter("Name"); //商户订单号，商户网站订单系统中唯一订单号，必填 String out_trade_no =request.getParameter("Order"); //付款金额，必填 ShopName String total_amount =request.getParameter("Money"); //商品描述，可空 String body ="购物测试"; // 该笔订单允许的最晚付款时间，逾期将关闭交易。取值范围：1m～15d。m-分钟，h-小时，d- 天，1c-当天（1c-当天的情况下，无论交易何时创建，都在0点关闭）。 该参数数值不接受小数点， 如 1.5h，可转换为 90m。 String timeout_express = "1c"; alipayRequest.setBizContent("{\"out_trade_no\":\"" + out_trade_no + "\"," + "\"total_amount\":\"" + total_amount + "\"," + "\"subject\":\"" + subject + "\"," + "\"body\":\"" + body + "\"," + "\"timeout_express\":\""+ timeout_express +"\"," + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}"); /* //请求 String url = ""; try {url = alipayClient.pageExecute(alipayRequest).getBody(); //调用SDK生 成表单 } catch (AlipayApiException e) { e.printStackTrace(); }response.setContentType("text/html;charset=" + AlipayConfig.CHARSET); return url;*/ //这两种方式都是可以的，就是上面那种可能很容易报错，看运气是否成功 //请求 String form = ""; try {form = alipayClient.pageExecute(alipayRequest).getBody(); //调用SDK生 成表单 } catch (AlipayApiException e) {e.printStackTrace(); }response.setContentType("text/html;charset=" + AlipayConfig.CHARSET); response.getWriter().write(form);//直接将完整的表单html输出到页面 response.getWriter().flush();response.getWriter().close(); return form;
