thinkphp alipay wechatpay

导读：

最近开发的一套支付系统，需要对接支付宝和微信支付的主流接口，支付宝有沙箱测试环境和沙箱测试账号，对接非常方便，最想吐槽的就是微信支付，连测试商户账号都不提供，叫你自己申请正式的商户，而且申请非常麻烦，没有正规的企业公司资质，个人开发者根本申请不到。如果不是在公司里上班，建议大家还是别折腾微信支付的了，麻烦！给大家看看我的支付系统体验收银台：

我的支付接口代码都是整合在extend扩展目录里，这样封装方便后期维护和在其他项目里直接使用：

直接分享代码给大家，里面有详细注释，只要不是很菜的程序员，相信都能看得懂，这里就不多做解释了。
