发现get_client_ip在局域网代理模式下面部分机器无法获取IP,故修改get_client_ip如下解决,但也有可能是我们这边服务器配置的问题:
修改位置:ThinkPHP\Common\funcitons.php->get_client_ip()
function get_client_ip($type = 0) {
$type = $type ? 1 : 0;
static $ip = NULL;
if ($ip !== NULL) return $ip[$type];
if($_SERVER['HTTP_X_REAL_IP']){//nginx 代理模式下,获取客户端真实IP
$ip=$_SERVER['HTTP_X_REAL_IP'];
}elseif (isset($_SERVER['HTTP_CLIENT_IP'])) {//客户端的ip
$ip = $_SERVER['HTTP_CLIENT_IP'];
}elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {//浏览当前页面的用户计算机的网关
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
$pos = array_search('unknown',$arr);
if(false !== $pos) unset($arr[$pos]);
$ip = trim($arr[0]);
}elseif (isset($_SERVER['REMOTE_ADDR'])) {
$ip = $_SERVER['REMOTE_ADDR'];//浏览当前页面的用户计算机的ip地址
}else{
$ip=$_SERVER['REMOTE_ADDR'];
}
// IP地址合法验证
$long = sprintf("%u",ip2long($ip));
$ip = $long ? array($ip, $long) : array('0.0.0.0', 0);
return $ip[$type];
}
