故障描述： 退出登錄時出現”您當前的訪問請求當中含有非法字符，已經被系統拒絕“錯誤。如下圖： 解決方法： 打開 /source/class/discuz/discuz_application.php 文件 找到 private function _xss_check() { static $check = array('"', '>', '<', '/'', '(', ')', 'CONTENT-TRANSFER-ENCODING'); if(isset($_GET['formhash']) && $_GET['formhash'] !== formhash()) { system_error('request_tainting'); } if($_SERVER['REQUEST_METHOD'] == 'GET' ) { $temp = $_SERVER['REQUEST_URI']; } elseif(empty ($_GET['formhash'])) { $temp = $_SERVER['REQUEST_URI'].file_get_contents('php://input'); } else { $temp = ''; } if(!empty($temp)) { $temp = strtoupper(urldecode(urldecode($temp))); foreach ($check as $str) { if(strpos($temp, $str) !== false) { system_error('request_tainting'); } } } return true; } 修改為 private function _xss_check() { $temp = strtoupper(urldecode(urldecode($_SERVER['REQUEST_URI']))); if(strpos($temp, '<') !== false || strpos($temp, '"') !== false || strpos($temp, 'CONTENT-TRANSFER-ENCODING') !== false) { system_error('request_tainting'); } return true; }
