这是我编写的用于发送消息的控制器文件中的电子邮件类配置

$config = array(
                'protocol'  => 'smtp',
                'smtp_host' => 'smtp.gmail.com',
                'smtp_port' => 465,
                'smtp_user' => 'xxxx@gmail.com',
                'smtp_pass' => 'xxxxx',
                'mailtype'  => 'html',
                'charset'   => 'utf-8'
                );
