方法1

1.配置.env文件
MAIL_DRIVER=smtp
MAIL_HOST=smtp.qq.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=gncmdxbmzqlebeec(这里的密码连接邮件服务器的密码需要手动去配置，如QQ，则需要去QQ邮箱的账户去设置)
MAIL_ENCRYPTION=tls

2.编辑config/mail.php
'from' => [
        'address' => env('MAIL_FROM_ADDRESS', '[email protected]'),
        'name' => env('MAIL_FROM_NAME', '凯恩书店'),
    ],

3.发送邮件
$uuid = UUID::create();
$m3Email = new M3Email;
$m3Email->to = $email;
$m3Email->cc = '[email protected]';
$m3Email->subject = '凯恩书店验证';
$m3Email->content = '请于24小时内点击链接完成验证，http:://www.bookshop.com/service/validate_email'
                    . '&member_id=' . $member->id
                    . '&code=' . $uuid;
Mail::send('email_register', ['m3Email' => $m3Email], function($m) use ($m3Email){
    $m->to($m3Email->to, '尊敬的用户')
      ->cc($m3Email->cc)
      ->subject($m3Email->subject);
});

方法2

function send_email($email, $name, $subject, $data = [], $template = 'emails.test')
    {
        Mail::send($template, $data, function ($message) use ($email, $name, $subject) {
            //如果是数组；则群发邮件
            if (is_array($email)) {
                foreach ($email as $k => $v) {
                    $message->to($v, $name)->subject($subject);
                }
            } else {
                $message->to($email, $name)->subject($subject);
            }
        });
        if (count(Mail::failures()) > 0) {
            $data = ['status_code' => 500, 'message' => '邮件发送失败'];
        } else {
            $data = ['status_code' => 200, 'message' => '邮件发送成功'];
        }
        return $data;
    }
