冷文博客: 传送门
为什么要发这篇帖子呢?原因很简单,就是因为在一个稍稍正规一点的应用上都会有支付这个环节,我们日常的在线支付如今包括支付宝,微信钱包,QQ钱包,银行卡支付等这些主流的支付方式,现在可能大部分人都会选择支付宝或微信钱包,当然现在网上有一些站点使用递四方支付方式,如码支付和易支付,虽然也是可以的使用微信和支付宝在线支付,但其手续费高的离谱,而且第四方支付平台不是很可靠,所以我们就不考虑他。今天就拿支付宝来说,为啥要用支付宝?原因也很简单,支付宝为开发者模拟了一套真实的支付环境供开发者使用,如果想上线也非常简单,只需要更换一些配置即可轻松上线。
给出一份支付宝官方的支付流程 https://docs.open.alipay.com/194/105072/

/* 实际验证过程建议商户务必添加以下校验:
1、需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号,
2、判断total_amount是否确实为该订单的实际金额(即商户订单创建时的金额),
3、校验通知中的seller_id(或者seller_email) 是否为out_trade_no这笔单据的对应的操作方(有的时候,一个商户可能有多个seller_id/seller_email)
4、验证app_id是否为该商户本身。
