毕业设计中使用支付宝沙箱完成在线支付流程（一）https://developer.aliyun.com/article/1423176
四，沙箱支付相关API说明
支付宝支付提供了很多种支付应用场景以及对应的API应用，打开网址：https://open.alipay.com/api
可以看到有对应的应用类型：选中其中某一个进入，则有相关的文档介绍和API应用案例，所以学习和使用起来还是比较简单。
4.1 当面付
如果我们想通过支付宝生成二维码，让客户端扫描二维码进行支付，可以选择当面付：
https://open.alipay.com/api/detail?code=I1080300001000041016#api-detail-content
各个接口有在线文档和在线调试的案例，可以自行查看。以其中的统一收单线下交易预创建为例说明：

五，沙箱支付功能实现
我们今天就以电脑网站支付为例进行讲解实现。
后台开发实现步骤：
5.1：支付功能的实现
1、创建配置类：配置沙箱相关环境信息 把配置类中相关的信息改为自己的即可。

2、定义支付接口地址：用户点击立即购买后提交请求至下单接口，添加订单成功后，发送请求到支付接口，向支付宝发送支付请求。
前端页面代码：在前端工程src/comments/mall/MallPurchase.vue中
createOrder(formName){ this.$refs[formName].validate((valid) => { if (valid) { if(this.isVip){ this.order.payPrice = this.order.discountPrice; } let loading = this.$loading({lock: true, text: "订单提交中",background:"rgba(255,255,255,0.1)"}); this.$http.post('/order/add',this.$qs.stringify(this.order,{skipNulls: true})).then((rep)=>{ loading.close(); if(rep.data.code===200){ let orderNo = this.order.orderNo; let orderName = '新新商城-'+this.productInfo.productType+'-'+this.productInfo.productName+'支付订单'; let payPrice = this.order.payPrice; let loading = this.$loading({lock: true, text: "正在跳转支付页面",background:"rgba(255,255,255,0.1)"}); this.$http.post('/alipay/create?orderNo='+orderNo+'&orderName='+orderName+'&payPrice='+payPrice).then((response)=>{ loading.close(); const div = document.createElement('div'); div.innerHTML = response.data; document.body.appendChild(div); document.forms[document.forms.length-1].submit(); }).catch((err)=>{loading.close();this.$msg.error(err)}) } }).catch((err)=>{loading.close();this.$msg.error(err);}) this.orderFormVisible=false; }else{ return false; } }); }
后端对应的支付接口实现：AlipayController
/** * 创建支付 * @param orderNo * @param orderName * @param payPrice * @return */ @ResponseBody @PostMapping(value = "/create", produces = "text/html;charset=utf-8") public String create(@RequestParam("orderNo") String orderNo, @RequestParam("orderName") String orderName, @RequestParam("payPrice") String payPrice) { return alipayService.create(orderNo, orderName, payPrice); }
业务方法实现：
/** * 创建支付订单 * * @param orderId 订单编号 * @param orderName 订单名称 * @param payPrice 支付金额 * @return 支付表单 */ @Override public String create(String orderId, String orderName, String payPrice) { //创建支付宝支付连接客户端 AlipayClient client = new DefaultAlipayClient(AlipayConfig.URL, AlipayConfig.APPID, AlipayConfig.RSA_PRIVATE_KEY, AlipayConfig.FORMAT, AlipayConfig.CHARSET, AlipayConfig.ALIPAY_PUBLIC_KEY, AlipayConfig.SIGNTYPE); AlipayTradeWapPayRequest payRequest = new AlipayTradeWapPayRequest(); AlipayTradeWapPayModel model = new AlipayTradeWapPayModel(); model.setOutTradeNo(orderId); model.setSubject(orderName); model.setTotalAmount(payPrice); model.setProductCode(PRODUCTCODE); payRequest.setBizModel(model); payRequest.setReturnUrl(AlipayConfig.RETURN_URL); payRequest.setNotifyUrl(AlipayConfig.NOTIFY_URL); try { return client.pageExecute(payRequest).getBody(); } catch (AlipayApiException e) { log.error("[支付宝] 支付失败", e); } return null; }
此接口返回的字符串其实是一个FORM表单，并执行自动提交：所以接口执行完后自动跳转到支付宝支付平台页面。
<form name="punchout_form" method="post" action="https://openapi.alipaydev.com/gateway.do?charset=UTF-8&method=alipay.trade.wap.pay&sign=bdVLwcblQMIpdDuHtLtrT6J9KK4IH0Y0FgfS4TVO61VBrG8xfKHitFafkoNAKL6CvPjEoxAhr2cSjluRirt6FpLAffrTd0iVHctBD6JBoK3oUy1j472c8onqZ9x5y896bi3zRObobc7ygJEvvR04RdwIAQPPHObkKjvNEta5qqHOW9S%2FApZSBoPqBZozkijWXhsQDlCmIpvd%2FH4LlHAcpQe67owOAujsJezrGA2cg7Exm50rUGyiAVhA3ICsqi9PVFWU4FbD3jdELHTD3%2BgP2l7%2FLzWMeEIUj9Y0vw6wU9xI%2FhPl1emZGt9iUHLce3NetowYh96kdR6vnfYSYBZhJw%3D%3D&return_url=http%3A%2F%2Ft2vnvc.natappfree.cc%2Falipay%2Fsuccess¬ify_url=http%3A%2F%2Ft2vnvc.natappfree.cc%2Falipay%2Fnotify&version=1.0&app_id=2021000121607425&sign_type=RSA2×tamp=2022-07-17+16%3A09%3A55&alipay_sdk=alipay-sdk-java-4.10.192.ALL&format=json"> <input type="hidden" name="biz_content" value="{"out_trade_no":"2271716507374","product_code":"QUICK_WAP_WAY","subject":"新新商城-生活家电-米家互联网洗烘一体机Pro 20kg支付订单","total_amount":"3299.00"}"> <input type="submit" value="立即支付" style="display:none" > </form> <script>document.forms[0].submit();</script>
然后就进入到了我们文章开头展示的支付流程页面：
可以对照着沙箱的商家账户和买家账户的钱数来看看是否实现了买家账户扣款和商家账户收款的功能。
5.2：回调本地接口更改支付状态
在线支付成功了，买家支付宝的账户的钱也已经转移到了商家的账户，可是本地应用怎么知道支付是否成功呢？我们在本地的应用中也需要根据支付成功与否来更改订单的支付状态，这就需要我们定义回调通知接口来实现。
我们在AlipayConfig中已经定义了回调的接口地址：
/** * 异步通知地址 */ public static final String NOTIFY_URL = "http://"+CALLBACK+"/alipay/notify";
那么这个接口主要实现的功能就是根据支付的结果来实现订单状态的更新：
在AlipayController中定义alipay/notify接口：
/** * @param map */ @ResponseBody @PostMapping(value = "/notify") public String payNotify(@RequestParam Map<String, String> map) { if (TRADE_SUCCESS.equals(map.get(TRADE_STATUS))) { String payTime = map.get(TRADE_TIME); String tradeNo = map.get(OUT_TRADE_NO); String tradeName = map.get(TRADE_NAME); String payAmount = map.get(TRADE_AMOUNT); log.info("[支付成功] {交易时间：{},订单号：{},订单名称：{},交易金额：{}}", payTime, tradeNo, tradeName, payAmount); } return "success"; } /** * 支付回调成功 * @param map * @param response */ @GetMapping(value = "/success") public void success(@RequestParam Map<String, String> map, HttpServletResponse response) { try { String tradeNo = map.get(OUT_TRADE_NO); if (tradeNo.contains(VIP)) { openMember(response, tradeNo); } else { updateProductStatus(response, tradeNo); } } catch (IOException e) { e.printStackTrace(); } } /** * 支付成功，更新商品状态为待发货 * * @param response HTTP响应 * @param tradeNo 订单编号 * @throws IOException IO异常信息 */ private void updateProductStatus(HttpServletResponse response, String tradeNo) throws IOException { Integer orderId = orderService.selectIdByKey(orderNo); Order order = new Order(); order.setOrderId(orderId); order.setOrderState("待发货"); orderService.updateById(order); //跳转到我的订单页面 response.sendRedirect("http://localhost:8080/#/myOrder"); }
六，总结
支付宝沙箱支付给了我们一个模拟支付宝在线支付的环境来进行测试，在本地通过沙箱支付测试成功后，可以在实际应用中，将对应的账户修改为自己企业账号申请的对公支付的账户信息即可，支付宝对整个开发提供的文档和案例也是比较丰富的，对于我们日常学习或做一些学校要求的简单课设来讲，这篇文章所讲解的基本支付功能应该能帮到大家的。如果还需要实现其它的像退款等相关功能，查看文中给的API接口地址，根据官方案例进行修改即可。
