谷粒商城高级篇—支付宝沙箱

支付宝沙箱

1、添加依赖

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.22.67.ALL</version>
</dependency>

2、配置类

@ConfigurationProperties(prefix = "alipay")
@Component
@Data
public class AlipayTemplate {

    // 应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号
    public String app_id;

    // 商户私钥，您的PKCS8格式RSA2私钥
    public String merchant_private_key;

    // 支付宝公钥,查看地址：https://openhome.alipay.com/platform/keyManage.htm 对应APPID下的支付宝公钥。
    public String alipay_public_key;

    // 服务器[异步通知]页面路径  需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
    // 支付宝会悄悄的给我们发送一个请求，告诉我们支付成功的信息
    public String notify_url;

    // 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问
    //同步通知，支付成功，一般跳转到成功页
    public String return_url;

    // 签名方式
    private  String sign_type;

    // 字符编码格式
    private  String charset;

    //订单超时时间
    private String timeout = "30m";

    // 支付宝网关； https://openapi.alipaydev.com/gateway.do
    public String gatewayUrl;

    public  String pay(PayVo vo) throws AlipayApiException {

        //AlipayClient alipayClient = new DefaultAlipayClient(AlipayTemplate.gatewayUrl, AlipayTemplate.app_id, AlipayTemplate.merchant_private_key, "json", AlipayTemplate.charset, AlipayTemplate.alipay_public_key, AlipayTemplate.sign_type);
        //1、根据支付宝的配置生成一个支付客户端
        AlipayClient alipayClient = new DefaultAlipayClient(gatewayUrl,
                app_id, merchant_private_key, "json",
                charset, alipay_public_key, sign_type);

        //2、创建一个支付请求 //设置请求参数
        AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
        alipayRequest.setReturnUrl(return_url);
        alipayRequest.setNotifyUrl(notify_url);

        //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 = vo.getOut_trade_no();
        //付款金额，必填
        String total_amount = vo.getTotal_amount();
        //订单名称，必填
        String subject = vo.getSubject();
        //商品描述，可空
        String body = vo.getBody();

        alipayRequest.setBizContent("{\"out_trade_no\":\""+ out_trade_no +"\","
                + "\"total_amount\":\""+ total_amount +"\","
                + "\"subject\":\""+ subject +"\","
                + "\"body\":\""+ body +"\","
                + "\"timeout_express\":\""+timeout+"\","
                + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");

        String result = alipayClient.pageExecute(alipayRequest).getBody();

        //会收到支付宝的响应，响应的是一个页面，只要浏览器显示这个页面，就会自动来到支付宝的收银台页面
        System.out.println("支付宝的响应："+result);

        return result;

    }
}

3、配置文件

#支付宝相关的配置
alipay.app_id=appid
alipay.merchant_private_key=商户私钥
alipay.alipay_public_key=支付宝公钥
alipay.notify_url=异步通知
alipay.return_url=跳转地址 
alipay.sign_type=RSA2
alipay.charset=utf-8
alipay.gatewayUrl=https://openapi.alipaydev.com/gateway.do

4、PayVo

@Data
public class PayVo {

    private String out_trade_no; // 商户订单号 必填
    private String subject; // 订单名称 必填
    private String total_amount;  // 付款金额 必填
    private String body; // 商品描述 可空
}

4、去支付

@GetMapping(value = "/pay",produces = "text/html")
@ResponseBody
public String alipayQrcode(@RequestParam("orderSn") String orderSn) throws AlipayApiException {
    PayVo payVo = orderService.getOrderPay(orderSn);//根据订单号填好信息
    String pay = alipayTemplate.pay(payVo);	//调用pay方法，返回form表单给前端
    return pay;
}

5、前端去支付

<!-- 订单页面 -->
<template>
  <div style="padding: 0 50px">
      ...
    <el-result icon="success" title="订单提交成功" subTitle="请在30分钟内完成支付, 超时后将取消订单">
          <el-button type="primary" round @click="submitPay()">去支付</el-button>
    </el-result>
      ...
          <!--将返回的表单放到页面-->
    <div ref="alipayWap" v-html="alipay" />
  </div>
</template>

<script>
  export default {
    name: "order",
    data() {
      return {
        alipay:'',
        orderInfoFromDB: ''
        ...
      };
    },
    methods: {
      //去支付
      submitPay(){
        let orderSn = this.orderInfoFromDB.orderSn
        this.$http({
          url: this.$http.adornUrl("/order/web/pay"),
          method: "get",
          params: this.$http.adornParams({
            orderSn: orderSn
          })
        }).then(({data}) => {
          this.alipay = data;
          // 防抖避免重复支付
          this.$nextTick(() => {
            // 提交支付表单
            this.$refs.alipayWap.children[0].submit();
            setTimeout(() => {
              // this.toPayFlag = false;
            }, 500);
          });
        })
      },
        
      ...
    },
  };
</script>

6、异步通知

@RestController
public class OrderPayedListener {

    @Autowired
    AlipayTemplate alipayTemplate;

    @Autowired
    OrderService orderService;

    //支付宝异步通知
    @PostMapping("/pay/notify")
    public String handleAlipayed(PayAsyncVo vo, HttpServletRequest request) throws AlipayApiException, UnsupportedEncodingException {
        Map<String, String[]> parameterMap = request.getParameterMap();
        for(String key : parameterMap.keySet()){
            String value = request.getParameter(key);
            System.out.println("参数名："+key+"==>参数值："+value);
        }
        // 验签
        Map<String,String> params = new HashMap<String,String>();
        Map<String,String[]> requestParams = request.getParameterMap();
        for (Iterator<String> 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);
        }

        boolean signVerified = AlipaySignature.rsaCheckV1(params, alipayTemplate.getAlipay_public_key(), alipayTemplate.getCharset(), alipayTemplate.getSign_type()); //调用SDK验证签名
        if(signVerified){
            System.out.println("签名验证成功。。。");
            String result = orderService.handlePayResult(vo);
            return result;
        } else {
            System.out.println("签名验证失败。。。");
            return "error";
        }
    }
}

OrderServiceimpl

//处理支付宝支付结果
@Transactional(rollbackFor = Exception.class)
@Override
public String handlePayResult(PayAsyncVo vo) {
    // 1、保存交易流水
    PaymentInfoEntity infoEntity = new PaymentInfoEntity();
    infoEntity.setAlipayTradeNo(vo.getTrade_no());
    infoEntity.setOrderSn(vo.getOut_trade_no());
    infoEntity.setPaymentStatus(vo.getTrade_status());
    infoEntity.setCallbackTime(vo.getNotify_time());
    paymentInfoService.save(infoEntity);
    // 2、修改订单的状态
    if(vo.getTrade_status().equals("TRADE_SUCCESS") || vo.getTrade_status().equals("TRADE_FINISHED")){
        //支付成功
        String outTradeNo = vo.getOut_trade_no();
        this.updateOrderStatus(outTradeNo,OrderStatusEnum.PAYED.getCode());
    }
    return "success";
}
