提问by RajeshKumar.K
Is it possible to get the ip address of the user (visitor of my website) without using server side languagelike PHP?
是否可以在不使用PHP 等服务器端语言的情况下获取用户（我网站的访问者）的 IP 地址？
I have a problem while using the server language (PHP) because of load balancer for my server. I tried http_x_forwared_forthat is also not retrieving the perfect ip address.
由于我的服务器的负载平衡器，我在使用服务器语言 (PHP) 时遇到问题。我试过http_x_forwared_for也没有检索到完美的 IP 地址。

function get_client_ip() {
$ipaddress = '';
if (getenv('HTTP_CLIENT_IP'))
$ipaddress = getenv('HTTP_CLIENT_IP');
else if(getenv('HTTP_X_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_X_FORWARDED_FOR');
else if(getenv('HTTP_X_FORWARDED'))
$ipaddress = getenv('HTTP_X_FORWARDED');
else if(getenv('HTTP_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_FORWARDED_FOR');
else if(getenv('HTTP_FORWARDED'))
$ipaddress = getenv('HTTP_FORWARDED');
else if(getenv('REMOTE_ADDR'))
$ipaddress = getenv('REMOTE_ADDR');
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
IN PHP :)
