苹果(apple)支付退款通知、api

背景:

用户在使用苹果支付购买商品后,可以直接像苹果申请退款,如果申请成功将导致商户直接构成损失。甚至某网络平台有这种专门薅羊毛的店铺,低价出售虚拟商品,再申请退款。所以有必要对用户发起的退款订单做及时响应,比如扣除对应的虚拟商品或像apple官方提供凭证使其退款不成功。

方案选型:

  1. 主动查询退款订单,文档地址
  2. 被动接收服务器通知,文档地址
主动请求退款api:
  1. 生成jwt身份标识,文档地址

    • 添加依赖项

      <!-- jwt -->
      		<dependency>
      			<groupId>com.auth0</groupId>
      			<artifactId>java-jwt</artifactId>
      			<version>3.8.1</version>
      		</dependency>
      
    • 示例代码

       private String generateJwtToken() throws Exception {
              Map<String, Object> headers = new HashMap<>();
              // apple指定ES256算法
              headers.put("alg", "ES256");
              // 密钥ID
              headers.put("kid", "***********");
              // jwt格式
              headers.put("typ", "JWT");
              return JWT.create()
                      .withHeader(headers)
                      // issId:见apple connect后台右上角
                      .withIssuer("*******-4f2e-4296-b2c7-**********")
                      // 签名日期
                      .withIssuedAt(new Date())
                      // 失效日期:最晚一个小时,否则报错401
                      .withExpiresAt(DateUtils.addHours(new Date(), 1))
                      // 目标接收者,固定值
                      .withAudience("appstoreconnect-v1")
                      // 包名,bundleId
                      .withClaim("bid", "com.********")
                      // 签名密钥,需要用到apple connect下载p8文件
                      .sign(Algorithm.ECDSA256(null, (ECPrivateKey) getPrivateKey("/payment/apple/AuthKey_****.p8")));
          }
      
          /**
           * 获取私钥
           * @param filename apple connect下载的p8文件路径
           * @return
           * @throws Exception
           */
          private PrivateKey getPrivateKey(String filename) throws Exception {
              String content = new String(Files.readAllBytes(Paths.get(filename)), StandardCharsets.UTF_8);
              try {
                  String privateKey = content.replace("-----BEGIN PRIVATE KEY-----", "")
                          .replace("-----END PRIVATE KEY-----", "")
                          .replaceAll("\\s+", "");
      
                  KeyFactory kf = KeyFactory.getInstance("EC");
                  return kf.generatePrivate(new PKCS8EncodedKeySpec(Base64.getDecoder().decode(privateKey)));
              } catch (InvalidKeySpecException e) {
                  throw new RuntimeException("Invalid key format");
              }
          }
      
  2. 请求、解析数据:

    • API地址:生产环境:GET https://api.storekit.itunes.apple.com/inApps/v2/refund/lookup/{originalTransactionId};沙盒环境:GET https://api.storekit-sandbox.itunes.apple.com/inApps/v2/refund/lookup/{originalTransactionId}

    • 示例代码和返回值:

        private RefundHistResponseVO getRefundHist() throws Exception {
              String token = generateToken();
              HttpHeaders header = new HttpHeaders();
              header.set("Authorization", "Bearer "+ token);
              RequestEntity<Map<String, String>> requestEntity = new RequestEntity<>(header, HttpMethod.GET, URI.create("https://api.storekit-sandbox.itunes.apple.com/inApps/v2/refund/lookup/2000000308586738"));
              ResponseEntity<RefundHistResponseVO> exchange = restTemplate.exchange(requestEntity, RefundHistResponseVO.class);
              return exchange.getBody();
       }
      
      		@Data
          public static class RefundHistResponseVO{
              /**
               * 同一个用户的下的退款订单列表,jws格式
               */
              private List<String> signedTransactions;
      
              /**
               * 分页token
               * signedTransactions最大数量是20条,超过20条需要下一次请求带上分页token
            */
              private String revision;
       
              /**
               * 是否有下一页
               */
              private Boolean hasMore;
          }
      
      {
          "signedTransactions": [

                  TransactionResponseVO responseVO = JSONObject.parseObject(new String(Base64.getDecoder().decode(decode.getPayload())), TransactionResponseVO.class);
                  // do something

    • 这里使用的是v2版本的api接口,有几个注意点:

      1. 返回每页大小是20,下一页请求需带上revision参数,v1版本接口是50条且明文显示,官方不建议使用,文档地址

      2. 此接口只能查询已成功的退款订单(在生产环境,用户发起退款会有12小时的审核时间,开发者可以提供凭证证明商品发放成功),不能查询已发起但未通过的退款申请。

      3. original_transaction_id是必传参数,可以是任意一笔交易id,重点是交易id所关联的用户:apple ID,也就是说同一个appleId产生的订单在这个接口返回的结果是一样的。(吐槽一下苹果的api。。这个接口不能查询app范围内的所有退款订单,因为订单id是必传字段,但返回值跟这笔订单又没有强关联,而是关联用户)

      4. 如果需要做邮件实时通知、用户发起退款申请后自动响应。建议使用另外一种方法:接收服务器通知

    接收服务器通知:
    1. 配置服务器通知url:文档地址,步骤挺简单的,打开应用配置,设置沙盒和生产环境的服务器接口地址即可。注意这里也选择V2版本通知,不建议使用V1版本。

    2. 通知类型:文档地址,这里主要关注几个消耗品商品购买的类型(其他类型包含订阅类型购买的变更通知有需要的可以自行对接):

      • CONSUMPTION_REQUEST:用户发起退款
      • REFUND:用户退款成功
      • TEST:通过api发起的测试通知,测试服务器的通知url是否配置成功
    3. 官方提供的沙盒环境测试退款方法:文档地址,需要在本地xcode跑StoreKit Test,挺麻烦的需要ios开发人员支持。这里提供一个免费的webhook网址,可以用于本地测试接收通知:https://webhook.site/

    4. 用户发起退款申请后,服务器会收到一个notificationType = CONSUMPTION_REQUEST 的通知,代表用户发起退款,开发者可以在接收通知的逻辑中调用发送消费信息的api,以证明用户退款无效:文档地址

    5. 苹果审核退款申请通过后,服务器会收到一个notificationType = REFUND 的通知,代表退款成功,开发者可以在处理扣除虚拟商品等操作。下面是退款通知的数据示例及验证签名代码:

      • 请求报文:

        {"signedPayload":"eyJhbGciOiJFUzI1NiIsIng1YyI6WyJNSUlFTURDQ0E3YWdBd0lCQWdJUWFQb1BsZHZwU29FSDBsQnJqRFB2OWpBS0JnZ3Foa2pPUFFRREF6QjFNVVF3UWdZRFZRUURERHRCY0hCc1pTQlhiM0pzWkhkcFpHVWdSR1YyWld4dmNHVnlJRkpsYkdGMGFXOXVjeUJEWlhKMGFXWnBZMkYwYVc5dUlFRjFkR2h2Y21sMGVURUxNQWtHQTFVRUN3d0NSell4RXpBUkJnTlZCQW9NQ2tGd2NHeGxJRWx1WXk0eEN6QUpCZ05WQkFZVEFsVlRNQjRYRFRJeE1EZ3lOVEF5TlRBek5Gb1hEVEl6TURreU5EQXlOVEF6TTFvd2daSXhRREErQm..."}
        
      • 验签并解析数据

        		/**
             * 验证签名
             * @param decodedJWT
             * @return

        		private JSONObject verifyAndGet(String jws) throws CertificateException {
            		DecodedJWT decodedJWT = JWT.decode(jws);
                // 拿到 header 中 x5c 数组中第一个
                String header = new String(java.util.Base64.getDecoder().decode(decodedJWT.getHeader()));
                String x5c = JSONObject.parseObject(header).getJSONArray("x5c").getString(0);
        
                // 获取公钥
                PublicKey publicKey = getPublicKeyByX5c(x5c);
        
                // 验证 token
                Algorithm algorithm = Algorithm.ECDSA256((ECPublicKey) publicKey, null);
        
                try {
                    algorithm.verify(decodedJWT);
                } catch (SignatureVerificationException e) {
                    return throw new RunTimeException();
                }
        				// 解析数据
                JSONObject payload = JSONObject.parseObject(new String(java.util.Base64.getDecoder().decode(decodedJWT.getPayload()));
        			
            }
        
        
        		/**
             * 获取公钥

             */
            private PublicKey getPublicKeyByX5c(String x5c) throws CertificateException {
                byte[] x5c0Bytes = java.util.Base64.getDecoder().decode(x5c);
                CertificateFactory fact = CertificateFactory.getInstance("X.509");
                X509Certificate cer = (X509Certificate) fact.generateCertificate(new ByteArrayInputStream(x5c0Bytes));
                return cer.getPublicKey();
            }
        
        
      • 解析的json示例

        {
          "notificationType": "REFUND",
          "notificationUUID": "334d1548-****-4ea9-****-e104731870b9",
          "data": {

          },
          "version": "2.0",
          "signedDate": 1680778196476
        }
        
      • 需要注意的是这里的signedTransactionInfo依然是一个jws格式,且字段与主动查询的结果一致,用上面的代码和vo类再解码一次

         DecodedJWT decode = JWT.decode(signedTransactionInfo);
                    TransactionResponseVO responseVO = JSONObject.parseObject(new String(Base64.getDecoder().decode(decode.getPayload())), TransactionResponseVO.class);
        
      • 关于后置的业务处理就不过多赘述了,毕竟每个公司的业务不同,需要处理的逻辑也不同,没有参考价值。与产品沟通即可。
