ecshop后台有时候会自动登出，而且还会很频繁，频繁的自动登出就严重的影响到了后台使用。
修改lib_base.php文件real_ip()函数，在real_ip函数中添加我标注的部分代码：
function real_ip()
{
static $realip = NULL;
if ($realip !== NULL)
{
return $realip;
}
if(isset($_COOKIE['real_ipd']) && !empty($_COOKIE['real_ipd'])){
$realip = $_COOKIE['real_ipd'];
return $realip;
}
if (isset($_SERVER))
{
if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
$arr = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach ($arr AS $ip)
{
$ip = trim($ip);
if ($ip != 'unknown')
{
$realip = $ip;
break;
}
}
}
elseif (isset($_SERVER['HTTP_CLIENT_IP']))
{
$realip = $_SERVER['HTTP_CLIENT_IP'];
}
else
{
if (isset($_SERVER['REMOTE_ADDR']))
{
$realip = $_SERVER['REMOTE_ADDR'];
}
else
{
$realip = '0.0.0.0';
}
}
}
else
{
if (getenv('HTTP_X_FORWARDED_FOR'))
{
$realip = getenv('HTTP_X_FORWARDED_FOR');
}
elseif (getenv('HTTP_CLIENT_IP'))
{
$realip = getenv('HTTP_CLIENT_IP');
}
else
{
$realip = getenv('REMOTE_ADDR');
}
}
preg_match("/[\d\.]{7,15}/", $realip, $onlineip);
$realip = !empty($onlineip[0]) ? $onlineip[0] : '0.0.0.0';
setcookie("real_ipd", $realip, time()+36000, "/");
return $realip;
}
