| 故障描述: 退出登录时出现”您当前的访问请求当中含有非法字符,已经被系统拒绝“错误。如下图:
 
   
 解决方法:
 打开 \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;
 }
 
 修改为
 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;
 }
