Services within the docker can not get the user's real IP

Background: MySQL database and Redis running on the host (Linux), server operating within docker, web operating within Nginx (Nginx runs in the docker), acquired user IP is 10.0.0.10 similar docker internal IP

Demand: get real IP

method:

　　　A, Nginx modify the configuration file, the docker container] [/etc/nginx/conf.d/default.conf

　　　　　　

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /web;
        index  index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #

    location /api/ {
        HTTP proxy_pass: // Base-Framework-Server /; 
        Set # Below is done to obtain the real IP
        proxy_set_header    X-Real-IP        $remote_addr;
        proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
        proxy_set_header    HTTP_X_FORWARDED_FOR $remote_addr;
        proxy_set_header    X-Forwarded-Proto $scheme;
        proxy_redirect      default;
    }

}

 

　　　Second, the increase in [tools] HttpUtil

　　　　

import org.springframework.util.StringUtils;

import javax.servlet.http.HttpServletRequest;

/**
 * @ClassName HttpUtil
 * @Description Http Tools
 * @Author AAFE (WeChat: xskdjs945)
 * @Date 2019/11/28 10:19
 * @Version 1.0
 **/
public class HttpUtil {

    /**
     * Get real client IP
     *
     * @param request
     * @return
     */
    public static String getClientIP(HttpServletRequest request) {

        // Nginx need to set configuration 
        String request.getHeader IP = ( " X-Real-the IP- " );
         IF (StringUtils.isEmpty (IP)) {
            ip = request.getRemoteAddr();
        }
        return ip;
    }

}
