php版如何开发银联支付接口

小编给大家分享一下php版如何开发银联支付接口，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！

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;* @date:20151202* **/class NetPayAction extends BaseAction{//在类初始化方法中，引入相关类库public function _initialize() { header("Content-type:text/html;charset=utf-8"); vendor('Netpay.util.common',"",".php"); //导入加密核心文件夹 vendor('Netpay.util.SecssUtil',"",".class.php"); //导入加密核心文件夹 vendor('Netpay.util.Settings_INI',"",".php"); //导入加密核心文件夹 vendor('Netpay.util.Settings',"",".php"); //导入加密核心文件夹 $this->securityPropFile= $_SERVER['DOCUMENT_ROOT'] .
