WordPress使用CDN后获取用户真实IP
在主题文件function.php下添加以下代码即可解决：/**
* 获取用户真实IP
*/
function getIP()
{
static $realIP;
if (isset($_SERVER)){
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
$realIP = explode(',', $_SERVER["HTTP_X_FORWARDED_FOR"]);
$realIP = $realIP;
} else if (isset($_SERVER["HTTP_CLIENT_IP"])) {
$realIP = $_SERVER["HTTP_CLIENT_IP"];
} else {
$realIP = $_SERVER["REMOTE_ADDR"];
}
} else {
if (getenv("HTTP_X_FORWARDED_FOR")){
$realIP = getenv("HTTP_X_FORWARDED_FOR");
} else if (getenv("HTTP_CLIENT_IP")) {
$realIP = getenv("HTTP_CLIENT_IP");
} else {
$realIP = getenv("REMOTE_ADDR");
}
}
$_SERVER['REMOTE_ADDR'] = $realIP;
//return $realIP;
}
add_action( 'init', 'getIP' );
