nginx 返回真实IP

https 访问时，有接口有http时，且需要知道真实主机访问IP，配置如下

location /dev-api/ {
                proxy_set_header Host $host:$server_port;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           	proxy_pass http://gateway/;
           	proxy_set_header X-Forwarded-Proto https;
           	proxy_redirect http:// https://;
   		}
