1.云豹node服务原始依赖于http协议，目前浏览器已经不支持http和https混合使用，所以需要为node.js支持https.

解决思路如下：

1.使用nginx进行端口转发，将域名转发至云豹的node.js端口19967端口。
2.如何更新ssl证书（宝塔创建一个站点，域名为聊天服务器地址域名，然后申请免费的ssl证书，打开站点配置文件复制ssl证书地址，然后修改到下面的nginx配置文件中）

server {
 listen 443 ssl http2;
 listen [::]:443 ssl http2;
 server_name 直播服务器域名;
 ssl_certificate    /www/server/panel/vhost/cert/***.cn/fullchain.pem;
 ssl_certificate_key    /www/server/panel/vhost/cert/***.cn/privkey.pem;

 }
}
