常用的获取客户端的IP地址的方法:
1)
function getRemoteIp(){
if(isset($_SERVER['HTTP_X_FORWARDED_FOR'])){
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
elseif(isset($_SERVER['HTTP_CLIENT_IP'])){
$ip = $_SERVER['HTTP_CLIENT_IP'];
}
elseif(getenv('HTTP_X_FORWARDED_FOR')){
$ip = getenv('HTTP_X_FORWARED_FOR');
}
elseif(getenv('HTTP_CLIENT_IP')){
$ip = getenv('HTTP_CLIENT_IP');
}
elseif($_SERVER['REMOTE_ADDR']){
$ip = $_SERVER['REMOTE_ADDR'];
}
else{
$ip = null;
}
return $ip;
}
服务器(Linux)获取公网IP:
curl ifconfig.me curl http://members.3322.org/dyndns/getip curl http://icanhazip.com curl ident.me curl http://ipecho.net/plain curl http://whatismyip.akamai.com ...
