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

1、配置nginx.con

server {listen 80;server_namelocalhost;#charset koi8-r;#access_loglogs/host.access.logmain;location / { proxy_pass http://127.0.0.1:8080; root html; indexindex.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_page404/404.html;# redirect server error pages to the static page /50x.html#error_page 500 502 503 504/50x.html;location = /50x.html {root html;}

2、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();} /*** * 获取客户端IP地址;这里通过了Nginx获取;X-Real-IP */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
