准备:
1、alipay官方下载最新接口类库
2、解压后,将目录"\即时到账交易接口-create_direct_pay_by_user\demo\create_direct_pay_by_user-PHP-UTF-8\lib"复制到 application\third_party目录下,并改名lib为alipay
3、同样复制cacert.pem文件到"application\third_party\alipay"目录下,这个不是必须的,在走ssl通道时用到的证书
代码实例:
以下只列出controller部分代码,view与model根据自己实际需要去编写
PHP复制代码
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
