荆轲刺秦王

公司的邮箱发送验证码功能之前一直正常工作但是最近停止了查看代码发现邮件类使用的是codeigniter框架的Email class

原有的代码是：
/application/config.php

php">'mail'					=>['protocol'	=>	'smtp','smtp_host'	=>	'mail.baidu.com','smtp_user'	=>	'root','smtp_pass'	=>	'root'],

common.php 公共函数类:

php">function send_email($to, $subject, $message,$from='',$title="通知",$priority=3,$file_url='',$cc='',$bcc='') {$config = config('mail');if(get_client_ip()=='127.0.0.1' && IS_WIN){$to = 'yaowei.liu@chipwealth.com';}if(strlen($from)==0){$from='ad@chipwealth.com';}if(strlen($title)==0){$title="通知";}$email = new Email($config);$email->from($from, $title);$email->to($to);$email->set_priority($priority);if($cc){$email->cc($cc);}if($bcc){$email->bcc($bcc);}$email->attach($file_url);$email->subject($subject);$email->message($message);if($to != 'aa@aa.com'){$email->send();/**$res = $email->print_debugger();var_dump($res);exit();**/}}

Email类使用的是 codeigniter 的Email类

详情见:Email Class — CodeIgniter 4.4.5 documentation

php">/*** CodeIgniter Email Class** Permits email to be sent using Mail, Sendmail, or SMTP.** @package		CodeIgniter* @subpackage	Libraries* @category	Libraries* @author		EllisLab Dev Team* @link		https://codeigniter.com/user_guide/libraries/email.html*/

收到的错误代码：

需要注意的是,如果想打印bug记得用email类的:

php">$email->print_debugger();

这个代码以前曾正常工作，但是现在却不能正常工作

最后发现是因为没有设置:

php">$config['crlf']     = "\r\n";
$config['newline']  = "\r\n";

那么在我的代码中我就需要设置email类的config

php">'mail'					=>['protocol'	=>	'smtp','smtp_host'	=>	'mail.baidu.com','smtp_user'	=>	'root','smtp_pass'	=>	'root','crlf'      =>  "\r\n",'newline'   =>  "\r\n",],

然后更新代码，就发现可以正常发送邮件了。这个问题似乎是因为 Codeigniter默认情况下没有这样做。
