jsp获取客户端IP地址的方法

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。
