java实现支付宝h5手机支付
- 2019 年 12 月 16 日
- 筆記
一.首先去支付宝申请好应用，以及开通手机快捷支付。
二.支付宝开放平台的API文档
https://docs.open.alipay.com/203/107090/
在application.yml封装属性
@Value("${app.ali-pay-appId}") private String APP_ID; /** * 应用私钥 */ @Value("${app.ali-pay-merchantPrivateSign}") private String APP_PRIVATE_KEY; /** * 支付宝公钥 */ @Value("${app.ali-pay-aliPublicSign}") private String ALIPAY_PUBLIC_KEY; /** * 回调地址 */ @Value("${app.ali-pay-notifyUrl}") private String notify_url; /** * 签名类型 */ @Value("${app.ali-pay-signType}") private String SIGN_TYPE; /** * 编码集 */ @Value("${app.ali-pay-charset}") private String CHARSET; /** * 支付宝网关 */ @Value("${app.ali-pay-payGateWay}") private String URL; @Value("${app.order-pay-switch}") private String flag;
统一下单接口
//实例化阿里支付 AlipayClient alipayClient = new DefaultAlipayClient(URL, APP_ID, APP_PRIVATE_KEY, FORMAT, CHARSET, ALIPAY_PUBLIC_KEY, SIGN_TYPE); //创建api对应的request AlipayTradeWapPayRequest alipayRequest = new AlipayTradeWapPayRequest(); alipayRequest.setNotifyUrl(notify_url); //订单号，后续修改为正式的 String outTradeNo = "" + System.currentTimeMillis(); Map<String, Object> maps = new HashMap<>(); maps.put("out_trade_no", outTradeNo); maps.put("total_amount", "0.01"); //产品名后续修改 maps.put("subject", "测试") maps.put("timeout_express", "3m"); String postData = JSONObject.toJSONString(maps); alipayRequest.setBizContent(postData); logger.info("requestId:{},function:{},request:{}",requestId,"支付宝支付请求参数",postData); String form = alipayClient.pageExecute(alipayRequest).getBody(); logger.info("requestId:{},function:{},response:{}" , requestId , "aliH5Pay" , form); logger.info("requestId:{},userId:{},function:{}",requestId,userIds,"发起支付宝支付请求");
//支付宝回调 @PostMapping(value = "/ali") @SkipUserAuth public String notify(HttpServletRequest request){ Map requestParams = request.getParameterMap(); String q = ""; for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) { String name = (String) iter.next(); String[] values = (String[]) requestParams.get(name); for (int i = 0; i < values.length; i++) { q+=name+"="+values[i]+"&"; } } System.out.println("支付宝支付结果通知"+requestParams.toString()); logger.info("requestId:{},function:{},response:{}",requestId,"支付宝支付结果通知",q); //获取支付宝POST过来反馈信息 Map<String,String> params = new HashMap<String,String>(); for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) { String name = (String) iter.next(); String[] values = (String[]) requestParams.get(name); String valueStr = ""; for (int i = 0; i < values.length; i++) { valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ","; } //乱码解决，这段代码在出现乱码时使用。 //valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8"); params.put(name, valueStr); } logger.info("requestId:{},function:{},response:{}", requestId , "支付宝回调" , params.toString()); //boolean AlipaySignature.rsaCheckV1(Map<String, String> params, String publicKey, String charset, String sign_type) try { //验证签名 boolean flag = AlipaySignature.rsaCheckV1(params, ALIPAY_PUBLIC_KEY, CHARSET,SIGN_TYPE); logger.info("requestId:{},function:{},response:{}", requestId, "支付宝回调验证签名", flag); if(flag){ if("TRADE_SUCCESS".equals(params.get("trade_status"))){ //商户订单号 String out_trade_no = params.get("out_trade_no"); logger.info("打印支付宝回调数据" + out_trade_no); //下面省略修改订单逻辑 } } } catch (AlipayApiException e) { e.printStackTrace(); logger.info("requestId:{} err",request ,e); logger.error("requestId:{} err",request ,e); } return "success"; }
