1、java代码
/** 获取客户端IP */ public static final String getClientIp(HttpServletRequest request) { String ip = request.getHeader("X-Forwarded-For"); if (StringUtils.isBlank(ip) || "unknown".equalsIgnoreCase(ip)|| "127.0.0.1".equalsIgnoreCase(ip)) { ip = request.getHeader("Proxy-Client-IP"); } if (StringUtils.isBlank(ip) || "unknown".equalsIgnoreCase(ip)|| "127.0.0.1".equalsIgnoreCase(ip)) { ip = request.getHeader("WL-Proxy-Client-IP"); } if (StringUtils.isBlank(ip) || "unknown".equalsIgnoreCase(ip)|| "127.0.0.1".equalsIgnoreCase(ip)) { ip = request.getHeader("X-Real-IP"); } if (StringUtils.isBlank(ip) || "unknown".equalsIgnoreCase(ip)|| "127.0.0.1".equalsIgnoreCase(ip)) { ip = request.getRemoteAddr(); } if (StringUtils.isBlank(ip) ||"127.0.0.1".equals(ip)|| ip.indexOf(":") > -1) { try { ip = InetAddress.getLocalHost().getHostAddress(); } catch (UnknownHostException e) { ip = null; } } // 对于通过多个代理的情况,第一个IP为客户端真实IP,多个IP按照‘,‘分割 if (ip != null && ip.length() > 15) { if (ip.indexOf(",") > 0) { ip = ip.substring(0, ip.indexOf(",")); } } return ip; }
2、nginx需要进行相应修改,重点 proxy_set_header
server {
listen xxxx;
server_name 127.0.0.1;
# 静态页面目录
root xxxxxxxxxx;
# 默认首页
index login.html;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Methods ‘GET,POST‘;
add_header Access-Control-Allow-Headers ‘DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization‘;
#proxy_cookie_path /* /*;
client_max_body_size 100m;
location / {
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers ‘DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization‘;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
......
}
}
