nginx如何获取真实客户端ip

Nginx作为反向代理服务器，即代理我们的服务端，下面介绍下如何配置nginx获取真实的客户端ip

配置nginx.con

    server {        listen       80;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {           proxy_pass Http://127.0.0.1:8080;           root   html;           index  index.html index.htm;        #获取真实ip配置        proxy_set_header Host $http_host;        proxy_set_header X-Real-IP $remote_addr;        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;        proxy_set_header X-Forwarded-Proto $scheme;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }

在java程序中可以通过如下方式获取：

    @GetMapping(value = "/getRealIp")    public String getRealIp(){        log.info(request.getRemoteAddr());        log.info(request.getRequestURL().toString());        log.info("端口" + request.getRemotePort() + "");        log.info("======================");        log.info("真实ip：{}",getClientIP());        return request.getRemoteAddr() + "\n" +                request.getRequestURL();    }     public String getClientIP() {        String fromSource = "X-Real-IP";        String ip = request.getHeader("X-Real-IP");        log.info("X-Real-IP 初始化值的ip:{} ", ip);//        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("X-Forwarded-For");            fromSource = "X-Forwarded-For";            log.info("X-Forwarded-For赋值成功ip:{} ", ip);//        }//        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("Proxy-Client-IP");            fromSource = "Proxy-Client-IP";            log.info("Proxy-Client-IP赋值成功ip:{} ", ip);//        }//        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getHeader("WL-Proxy-Client-IP");            fromSource = "WL-Proxy-Client-IP";            log.info("WL-Proxy-Client-IP赋值成功ip:{} ", ip);//        }//        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            ip = request.getRemoteAddr();            fromSource = "request.getRemoteAddr";            log.info("RemoteAddr赋值成功ip:{} ", ip);//        }        return ip;    }

这样就可以打印出真实ip了！即request.getHeader("X-Real-IP")的值
