关于苹果内购商品退款的开发联调
随手记还是比正经写文章要少些心智负担
苹果在今年6月的开发者大会上宣告支持普通商品的退款回调服务，只需要在开发者后台配置回调网址即可收到退款通知
由于中文资料的缺失直到最近才解决了这个问题。整理资料如下
nginx收到数据日志格式如下：

}] - [] - ""苹果直接以post json形式发送数据过来，接收后注意判断环境及receipt数据
latest_receipt_info中如果是退款的订单会返回cancellation_date等字段，可以作为判断是否退款的依据
总体来说，苹果难得的开放了这部分接口，但对开发者仍然不够友好。
没有开发环境，只能靠用户真实的退款后收到数据做参考，否则你在文档里连一个请求的完整参考示例都没有，很难保证上线不出问题。
另外这个数据苹果应该没有重发机制，可能会导致用户退款的没有处理的情况。
