Description
要想在程序中取得真实的IP,在执行nginx的configure时,必须指定参数“--with-http_realip_module”,
示例:
sudo ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module
然后修改nginx配置文件:
location / {
proxy_pass http://localhost:8080; #后端的web服务器
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
重启nginx: ./nginx -s reload 即可。
然后在express服务器里,通过 req.headers['x-real-ip']即可拿到真实ip地址
