创建支付订单

封装创建支付订单的WEB方法

编写ZfbController.java

@PostMapping("/nativePayOrder")
@ApiOperation("native付款")
public R nativePayOrder(@RequestBody PayOrderForm form, @RequestHeader HashMap header) {
    ValidatorUtils.validateEntity(form);
    String token = header.get("token").toString();
    Long userId = Long.parseLong(jwtUtils.getClaimByToken(token).getSubject());
    int orderId = form.getOrderId();
    UserEntity user = new UserEntity();
    user.setUserId(userId);
    QueryWrapper wrapper = new QueryWrapper(user);
    long count = userService.count(wrapper);
    if (count == 0) {
        return R.error("用户不存在");
    }

    OrderEntity order = new OrderEntity();
    order.setUserId(userId.intValue());
    order.setId(orderId);
    order.setStatus(1);
    wrapper = new QueryWrapper(order);
    count = orderService.count(wrapper);
    if (count == 0) {
        return R.error("不是有效的订单");
    }
    //验证购物券是否有效
    //验证团购活动是否有效

    order = new OrderEntity();
    order.setId(orderId);
    wrapper = new QueryWrapper(order);
    order = orderService.getOne(wrapper);
    //向微信平台发出请求，创建支付订单
    String amount = order.getAmount() + "";

    try {
        AlipayClient client = new DefaultAlipayClient(
            gateway,
            app_appId,
            app_privateKey,
            "json",
            "UTF-8",
            app_publicKey,
            "RSA2"
        );
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        request.setReturnUrl("http://192.168.99.100:8848/mall/order.html");
        request.setNotifyUrl("http://www.demo.com");
        String subject = "Native付款";
        String body = "测试Native付款";
        request.setBizContent("{\"out_trade_no\":\"" + order.getCode() + "\","
        + "\"total_amount\":\"" + amount + "\","
        + "\"subject\":\"" + subject + "\","
        + "\"body\":\"" + body + "\","
        + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
        AlipayTradePagePayResponse response = client.pageExecute(request);
        String htmlCode = response.getBody();
        if (response.isSuccess()) {
            order.setPaymentType(2);
            UpdateWrapper updateWrapper = new UpdateWrapper();
            updateWrapper.eq("id", order.getId());
            orderService.update(order, updateWrapper);
            return R.ok().put("htmlCode", htmlCode);
        } else {
            return R.error("支付订单创建失败");
        }

    } catch (Exception e) {
        e.printStackTrace();
        return R.error("支付宝支付模块故障");
    }
}

编写订单页面

编写order.js文件

$.ajax({
    url:zfbUrl.nativePayOrder,
    type:"post",
    dataType:"json",
    contentType:"application/json",
    beforeSend: function (request) {
        request.setRequestHeader("token", localStorage.getItem("token"));
        request.setRequestHeader("ip", localStorage.getItem("ip"));
    },
    data:JSON.stringify({
        "orderId":orderId
    }),
    success:function(resp){
        if(resp.code==0){
            let htmlCode=resp.htmlCode
            // console.log(htmlCode)
            $("#htmlCode").html(htmlCode)
        }
    }
})
