}server {listen www.xxx.com:80;server_name www.xxx.com;location / {proxy_pass http://www.xxx.cn;}proxy_set_header Host $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
} 在原来配置的基础上加入后面的三条指令,就可以用request.getHeader(X-Forwarded-For);获取到访客的ip了. 附:Java获取客户端ip的实现 private static final String[] IP_HEADER_CANDIDATES {X-Forwarded-For,Proxy-Client-IP,WL-Proxy-Client-IP,HTTP_X_FORWARDED_FOR,HTTP_X_FORWARDED,HTTP_X_CLUSTER_CLIENT_IP,HTTP_CLIENT_IP,HTTP_FORWARDED_FOR,HTTP_FORWARDED,HTTP_VIA,REMOTE_ADDR };public static String getClientIpAddress(HttpServletRequest request) {for (String header : IP_HEADER_CANDIDATES) {String ip request.getHeader(header);if (ip ! null ip.length() ! 0 !unknown.equalsIgnoreCase(ip)) {int index ip.indexOf(,);if (index ! -1) {return ip.substring(0, index);}return ip;}}return request.getRemoteAddr();
