ngxin代理如何获取用户真实IP
1、修改nginx配置文件
在location模块下添加如下配置获取代理前的用户IP
proxy_set_header X-real-ip $remote_addr;
修改后配置参考如下:
location / {
try_files $uri $uri/ /index.html;
proxy_set_header X-real-ip $remote_addr;
}
2、java端获取用户IP
public static String getIpAddress() {
HttpServletRequest request = getRequest();
String ip = request.getHeader("X-Real-IP"); //取nginx反向代理前的用户真实IP
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("X-Forwarded-For");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("x-forwarded-for");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("WL-Proxy-Client-IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_CLIENT_IP");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getHeader("HTTP_X_FORWARDED_FOR");
}
if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
ip = request.getRemoteAddr();
}
return ip;
}
