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<dengwz7788@gmail.com>; * @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'] .

银联支付应该是算比较简单的！！
