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 sourceclassdiscuzdiscuz_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;
}
