Redis 队列读取不到域名

public function toMail($notifiable)
{
$key = str_random(15);
$expiredAt = now()->addMinutes(10);
Cache::put($key, ['email' => $notifiable->email], $expiredAt);
$url = config('app.url')."/email_verification/verify?key=$key";

return (new MailMessage)
            ->greeting($notifiable->name.'您好：')
            ->subject('注册成功，请验证您的邮箱'.$url)
            ->line('请点击下方链接验证您的邮箱')
            ->action('验证', $url);

}
我用reids队列运行邮件发送 $url的域名总是localhost 同步的方式却是正常的larashop.com
