使用Java接入苹果内购流程(附主要代码)

一、苹果内购介绍

在App Store上架的 APP ,如果订购的商品类型是虚拟的,非实物的,类似:虚拟币等,需要使用苹果自己的支付方式,即:IAP内购,并且苹果会抽30%的税。
上架商品可在 APP Store后台配置。

二、服务端验证支付票据

2.1 服务端逻辑

@Override     public boolean verifyIosPayReceipt(Long userId, AppIosPayReceiptVerifyParam param) {         String receipt = param.getReceipt();         String orderNo = param.getOrderNo();          // 校验订单号的有效性         boolean flag = IDUtil.validateOrderNo(orderNo);         if (!flag) {             throw new CustomizeException("订单号格式错误");         }          // 校验订单号是否存在         Orders orders = ordersRepository.getByOrderNo(orderNo);         if (null == orders) {             throw new CustomizeException("订单号不存在");         }          // 注意,有的票据在客户端接收时 加号 可能会被转换为 空格         String data = receipt.replace(" ", "+");         // 请求苹果服务器进行票据验证         String result = AppleVerifyUtil.verifyApple(data, 1);         JSONObject receiptData = JSONObject.parseObject(result);          // 解析票据         if (result == null) {             // 解析票据失败 或 网络问题             log.error("[ verify receipt error]");             return false;         }          // 支付环境是否正确         int status = receiptData.getInteger("status");         if (21007 == status) {             // 验证失败21007 走沙箱环境             result = AppleVerifyUtil.verifyApple(data, 0);             if (result == null) {                 //  解析票据失败                 log.error("[ verify receipt error]");                 return false;             }             receiptData = JSONObject.parseObject(result);             status = receiptData.getInteger("status");         }          if (0 == status) {             // 票据ID             String transactionId;             // 购买时间             Long purchaseDateMs;             // 商品ID 与在APP Store 后台配置的一致             String productId;             JSONObject receiptInfo = receiptData.getJSONObject("receipt");             if (receiptInfo == null) {                 return false;             }             JSONArray inAppList = receiptInfo.getJSONArray("in_app");             if (!CollectionUtils.isEmpty(inAppList)) {                 // ios7之前的数据格式                 JSONObject inApp = inAppList.getJSONObject(inAppList.size() - 1);                 transactionId = inApp.getString("transaction_id");                 purchaseDateMs = inApp.getLong("purchase_date_ms");                 productId = inApp.getString("product_id");             } else {                 // ios之后的数据格式                 transactionId = receiptInfo.getString("transaction_id");                 purchaseDateMs = receiptInfo.getLong("purchase_date_ms");                 productId = receiptInfo.getString("product_id");             }              // todo 判断product_id,看返回的product_id与实际的充值金额是不是一致,防止骗单               // todo 剩余业务逻辑             return true;         }         return false;     } 

2.2 苹果内购验证工具类

2.3 票据信息的数据结构

服务端携带票据请求苹果服务端验证成功后,苹果会返回解析后的票据信息。我们需要的信息都在receipt中。但是经过测试发现,出现了两种数据结构,分别是IOS7之前和IOS7之后。

  • IOS7之前的数据格式
{     "receipt": {         "original_purchase_date_pst": "2016-12-03 01:11:01 America/Los_Angeles",          "purchase_date_ms": "1480756261254",          "unique_identifier": "96f51b28f628493709966f33a1fe7ba",          "original_transaction_id": "1000000255766",          "bvrs": "82",          "transaction_id": "1000000255766",          "quantity": "1",          "unique_vendor_identifier": "FE358-1362-40FD-870F-DF788AC5",          "item_id": "11822945",          "product_id": "rjkf_itemid_1",          "purchase_date": "2016-12-03 09:11:01 Etc/GMT",          "original_purchase_date": "2016-12-03 09:11:01 Etc/GMT",          "purchase_date_pst": "2016-12-03 01:11:01 America/Los_Angeles",          "bid": "com.xxx.xxx",          "original_purchase_date_ms": "1480756261254"     },      "status": 0 } 
  • IOS7之后的数据结构
{     "status": 0,      "environment": "Sandbox",      "receipt": {         "receipt_type": "ProductionSandbox",          "adam_id": 0,          "app_item_id": 0,          "bundle_id": "com.xxx.xxx",          "application_version": "84",          "download_id": 0,          "version_external_identifier": 0,          "receipt_creation_date": "2016-12-05 08:41:57 Etc/GMT",          "receipt_creation_date_ms": "1480927317000",          "receipt_creation_date_pst": "2016-12-05 00:41:57 America/Los_Angeles",          "request_date": "2016-12-05 08:41:59 Etc/GMT",          "request_date_ms": "1480927319441",          "request_date_pst": "2016-12-05 00:41:59 America/Los_Angeles",          "original_purchase_date": "2013-08-01 07:00:00 Etc/GMT",          "original_purchase_date_ms": "1375340400000",          "original_purchase_date_pst": "2013-08-01 00:00:00 America/Los_Angeles",          "original_application_version": "1.0",          "in_app": [             {                 "quantity": "1",                  "product_id": "rjkf_itemid_1",                  "transaction_id": "10000003970",                  "original_transaction_id": "10000003970",                  "purchase_date": "2016-12-05 08:41:57 Etc/GMT",                  "purchase_date_ms": "1480927317000",                  "purchase_date_pst": "2016-12-05 00:41:57 America/Los_Angeles",                  "original_purchase_date": "2016-12-05 08:41:57 Etc/GMT",                  "original_purchase_date_ms": "1480927317000",                  "original_purchase_date_pst": "2016-12-05 00:41:57 America/Los_Angeles",                  "is_trial_period": "false"             }         ]     } }

三、接入IOS回调通知

3.1 配置回调通知url

打开应用配置,设置沙盒喝生产环境的服务器接口地址即可。 苹果官方配置页面
注意:最好选择V2版本通知,不建议使用V1版本,V1版本即将废弃。

3.2 通知类型

通知类型(notification_type):苹果官方文档地址
根据解析出来的notification_type字段来判断回调通知具体是什么场景,然后进行对应的业务逻辑处理。

  • DID_RENEW:表示客户的订阅已成功自动续订新的交易周期。为客户提供对订阅内容或服务的访问权限。
  • REFUND:表示 App Store 已成功对消耗性应用内购买、非消耗性应用内购买或非续订订阅的交易进行退款。包含退款交易的时间戳。并标识原始交易和产品。其中包含原因。

3.3 测试

官方提供的沙盒环境测试退款方法:苹果官方文档地址,需要在本地xcode跑StoreKit Test,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/

3.4 处理回调通知

  • 请求报文结构

  • 验证签名,解析数据

  • 解析出来的JSON数据
{   "notificationType": "REFUND",   "notificationUUID": "334d1548-****-4ea9-****-e104731870b9",   "data": {     "appAppleId": 1617026651,     "bundleId": "com.*****",     "bundleVersion": "1",     "environment": "Sandbox",     "signedTransactionInfo": "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..."   },   "version": "2.0",   "signedDate": 1680778196476 } 

data中的signedTransactionInfo依然是一个jws格式,且字段与主动查询的结果一致,用上面的解析代码再解码一次。

  • 处理回调通知接口Java代码
/**  * IOS通知请求体  */ @Data public class IosNotificationRequest {     private String signedPayLoad; } 
	/**      * 苹果ios服务通知回调      */     @RequestMapping("/iosNotification")     public boolean iosNotification(@RequestBody IosNotificationRequest request) {         log.info("apple ios server notification come in, request:{}", JSONObject.toJSONString(request));         String signedPayLoad = request.getSignedPayLoad();         try {             JSONObject payload = AppleVerifyUtil.verifyAndGet(signedPayLoad);              String notificationType = payload.get("notificationType").toString();              JSONObject data = payload.getJSONObject("data");             log.info("apple ios server notification verify success, payload:{}, data:{}", payload, data);             String signedTransactionInfo = data.get("signedTransactionInfo").toString();             String environment = data.get("environment").toString();              JSONObject transactionInfo = AppleVerifyUtil.verifyAndGet(signedTransactionInfo);             String transactionId = transactionInfo.get("transactionId").toString();             String originalTransactionId = transactionInfo.get("originalTransactionId").toString();             String productId = transactionInfo.get("productId").toString();              if ("DID_RENEW".equals(notificationType)) {                 // todo 处理订阅续期业务逻辑              } else if ("REFUND".equals(notificationType)) {                 // todo 处理退款业务逻辑              } else {                 log.error("notificationType:{}未处理", notificationType);             }          } catch (CertificateException e) {             log.error("apple ios server notification verify error, signedPayLoad:{}", signedPayLoad, e);             return false;         }         return true;     } 

具体的业务处理这里就不过多赘述了,每个公司的业务不同,因此处理逻辑也不同,根据实际情况自行处理即可。
