Java实现的苹果IAP二次验证主要逻辑

来源：互联网发布：js游戏引擎编辑：程序博客网时间：2024/05/16 09:50

苹果IAP二次验证流程为：

一：客户端(iphone or ipad)向Apple SERVER发送购买请求

二：AppleSERVER返回购买成功的receipt(IAP在购买流程中，会给每一次购买行为创建一个SKPaymentTransaction，这个transaction会记录用户购买状态，如：

正在购买(SKPaymentTransactionStatePurchasing),

已购买(SKPaymentTransactionStatePurchased),

购买失败(SKPaymentTransactionStateFailed)。

而当transaction状态是 SKPaymentTransactionStatePurchased的时候，客户端就能得到一个transaction.transactionReceipt)

三、当客户端购买状态结束，收到经由苹果回发的Receipt是，获取客户端Receipt，经第三方平台进行二次验证，此时苹果服务器需要的数据格式为JSON，具体包含字段，由程序自行规定：例如：quantity(数量)，product_id（物品ID）,transaction_id（交易标识，此字段可做全局标识，唯一）,purchase_date(交易日期)。数据转换为Json编码格式，键名为"receipt-data"，值为上一步编码后的数据。具体格式为:

{
"receipt-data"
: "(编码后的数据)"

}

四、将此Json 经HTTP POST的请求，将数据发送到App Store，其地址为:

https://buy.itunes.apple.com/verifyReceipt （正式购买地址）

https://sandbox.itunes.apple.com/verifyReceipt （测试数据地址）

五、App Store的返回值也是一个JSON格式的对象，包含两个键值对， status和receipt:

{
"status"
: 0, （验证状态码，0标识通过，21007 标识此数据为测试数据，需交由sandbox进行再次验证）

"receipt"
: {提交的数据解析为明文返回}

}

下面为具体代码实现方式，作为参考，各位如认为可用，欢迎使用：
