php版银联支付接口开发简明教程

本文实例讲述了php版银联支付接口开发的方法。分享给大家供大家参考，具体如下：

支付接口现在有第三方的支付接口也有银行的支付接口。这里就来介绍php版本银联支付接口开发的方法。

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openssl

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

下面是我用thinkphp编写的一个支付类

/**
* 银联支付 v0.1
* @auther:summer<[e-mail]>;
* @date:20151202

}

银联支付应该是算比较简单的！！
