苹果内购小结 - iOS

此篇针对 iOS 支付进行一次小结,很久没碰这块了,有些方法 Apple 官方也进行了优化,故也将随之进行更新.

首先,code 部分将分为两部分,一部分在 appdelegate 中,另一部分单独封装在了一个类中执行,需要使用的地方调用的接口方法.

其次,大体支付流程为获取到充值价格订单列表后,选择对应的价格后向 Apple 发起支付请求,接收到 Apple 支付回调后,根据结果处理相关逻辑,最后将处理完成的结果反馈至用户.

其过程中会分为几个环节来处理:

若支付失败则执行异常处理并将最后处理结果信息反馈至用户;

若支付成功则对支付凭证校验,此篇文章中的校验过程分为两部分,先是由客户端自行校验,若校验成功则将相关用户信息和支付凭证发送至服务端进行二次校验;

其中,客户端优先进行交易凭证校验,校验失败则将校验的异常处理信息反馈至用户;反之,校验成功则再次将相关用户信息和本次支付凭证数据一并发送至服务端进行二次校验,最终将双重验证后的结果信息反馈至用户,从而为了避免刷单的情况.

最后,文章中具体处理逻辑中可能会因为需求的不同与实际有些小的出入,但大体流程应该是一致的,也会对应添加相应的注释,若存在不清楚的地方可以帖子下方留言沟通交流.

大致支付流程:

1.苹果APP(商家)

2.告诉苹果Store服务器要卖的商品

3.苹果审核完(告诉你是否可以卖)

4.用户(买商品)

5.苹果APP(商家)

6.开发票给(用户)

7.用户(拿着发票去苹果Store服务器付款)

8.付款成功(用户在APP里获得服务商品)

注:如果要模拟测试内购,需要用真机才可以测试

凭证校验地址:

开发环境:  https://sandbox.itunes.apple.com/verifyReceipt

生产环境:  https://buy.itunes.apple.com/verifyReceipt

凭证校验异常 code 参照码:

内购验证凭据返回结果状态码说明(status 状态)

21000 App Store无法读取你提供的JSON数据

21002 收据数据不符合格式

21003 收据无法被验证

21004 你提供的共享密钥和账户的共享密钥不一致

21005 收据服务器当前不可用

21006 收据是有效的，但订阅服务已经过期。当收到这个信息时，解码后的收据信息也包含在返回内容中

21007 收据信息是测试用（sandbox），但却被发送到产品环境中验证

21008 收据信息是产品环境中使用，但却被发送到测试环境中验证

 AppStore增加了验证内购(In App Purchasement)的方法, 就是苹果提供一个url地址:

 当购买成功时, 会得到苹果返回的一个收据(receipt), 苹果推荐的方法是将收据发给开发者的 server 服务端, 由 server 服务端向上述地址发起请求(post http)消息, 进行验证, 苹果将校验结果返回.此次交易凭证是真购买凭证还是伪购买凭证.
