DISCUZ論壇如需啟用論壇自帶的CC防護,請按照如下配置。
使用WAF後，用戶訪問網站的是通過WAF服務器間接訪問網站服務器的，Discuz論壇可能會在獲取用戶IP時，直接獲取WAF的IP，而不能直接獲取到用戶的真實IP，在此提出一些解決方案。
解決方法(DZ X2)：
1、打開DZ /source/class/class_core.php 文件。
2、找到第341行，或者搜索“HTTP_CLIENT_IP”，找到如下代碼：
function _get_client_ip() { $ip = $_SERVER['REMOTE_ADDR']; if (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR']) AND preg_match_all('#d{1,3}.d{1,3}.d{1,3}.d{1,3}#s', $_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) { foreach ($matches[0] AS $xip) { if (!preg_match('#^(10|172.16|192.168).#', $xip)) { $ip = $xip; break; } } } return $ip; }
3、將以上代碼修改為：
function _get_client_ip() { $ip = $_SERVER['REMOTE_ADDR']; if (isset($_SERVER['HTTP_X_REAL_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_REAL_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_REAL_FORWARDED_FOR']; } elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; } elseif (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; } return $ip; }
解決方法(DZ X2.5)：
1、打開文件sourceclassdiscuzdiscuz_application.php 找到如下代碼：。
private function _get_client_ip() { $ip = $_SERVER['REMOTE_ADDR']; if (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; } elseif(isset($_SERVER['HTTP_X_FORWARDED_FOR']) AND preg_match_all('#d{1,3}.d{1,3}.d{1,3}.d{1,3}#s', $_SERVER['HTTP_X_FORWARDED_FOR'], $matches)) { foreach ($matches[0] AS $xip) { if (!preg_match('#^(10|172.16|192.168).#', $xip)) { $ip = $xip; break; } } } return $ip; }
3、將以上代碼修改為：
private function _get_client_ip() { $ip = $_SERVER['REMOTE_ADDR']; if (isset($_SERVER['HTTP_X_REAL_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_REAL_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_REAL_FORWARDED_FOR']; } elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_X_FORWARDED_FOR'])) { $ip = $_SERVER['HTTP_X_FORWARDED_FOR']; } elseif (isset($_SERVER['HTTP_CLIENT_IP']) && preg_match('/^([0-9]{1,3}.){3}[0-9]{1,3}$/', $_SERVER['HTTP_CLIENT_IP'])) { $ip = $_SERVER['HTTP_CLIENT_IP']; } return $ip; }
以上操作後，登陸你的Discuz!論壇後台分別清除緩存即可。
Discuz! 3.0 可以參照 Discuz! 2.5。
