edusoho二次开发paypal支付功能-附源代码

集成paypal支付接口的，对象是海外用户，全部用US的信用卡结算； 项目结束的时候就有想法写一篇网站集成paypal的简易教程，方便以后的各位开发者

修改的文件路径是vendorcodeagesbiz-order-paysrcPayPayment；
增加PalPayGateway.php文件

<?php
namespace CodeagesBizPayPayment;
use CodeagesBizFrameworkServiceExceptionAccessDeniedException;

1、edusoho新版后台的界面，配置PayPal支付参数信息，主要还是商户邮箱

2、配置完之后，在前台测试课程购买的支付过程

3、选择PayPal支付订单，直接跳转到PayPal支付的页面！！！！！

4、支付完之后，就会进行回调，系统显示支付成功

最后
