我的域名是www.example.com，nginx文件如下所示，所以我的根路径是/var/www/campaignmanager/bannerad/public。example.com and nginx file like below. So my root path is /var/www/campaignmanager/bannerad/public.
因此，我的域在浏览器中打开，如www.example.com，但我想打开它，如example. com/campaignmanager或www. example. com/campaignmanagerexample.com but i want to open it likeexample.com/campaignmanagerorwww.example.com/campaignmanager
