打开 include/payment/alipay.php 文件
找到
$this->log_result("verify_success,订单号:".$order_sn); //将验证结果存入文件
在此代码下面添加如下代码（部分代码需要修改）
$mailbody = '';
$mailtitle = "订单号:".$order_sn."支付成功！";
$mailbody .= "这里是提示信息";
$email='464696980@qq.com';//改为要接收邮件的邮箱

$cfg_smtp_user = 'www.moke8.com'; //名称
$cfg_webname = '庐州生活博客园'; //站名称
$cfg_smtp_password = 'password'; //发件邮箱密码
$headers = "From: ".$cfg_smtp_usermail."\r\nReply-To: ".$cfg_smtp_usermail;
