银联电子支付 php chinapay

之前看我博客百度关键字的时候，很多人都是因为银联搜到我这里，一直想做一个demo 给大家，可惜没商户申请不到，这次机缘巧合帮朋友做支付三部曲：微信支付，支付宝支付和银联支付，其他两个支付都烂大街的，这里就只把银联支付分享给大家，因为涉及到客户的信息，所以就不提供源代码下载了。

银联支付，首先要注意二重要的部分：

PHP运行环境是5.4.18以上
开了扩展openss
开发手册上面的列子只做参考，因为基本都是错的。你可以试着去官网下一个demo。。。注意现在银联开发，没有测试密钥提供，只能在正式环境开发【20151219】

下面是我用ThinkPHP编写的一个支付类

银联支付应该是算比较简单的！！
