我是靠谱客的博主苗条硬币，这篇文章主要介绍jsp获取客户端IP地址的方法，现在分享给大家，希望可以做个参考。

本文实例讲述了jsp获取客户端IP地址的方法。分享给大家供大家参考，具体如下：

public static String getIpAddr(HttpServletRequest request) { 
  String 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;
}

希望本文所述对大家JSP程序设计有所帮助。
