• “抱歉，您的请求来路不正确或表单验证串不符，无法提交”

  打开“source\class\helper\helper_form.php”， 然后把“$_GET[‘formhash’] == formhash() ”修改为“$_G[‘formhash’] == formhash() ”

   

• 您当前的访问请求当中含有非法字符，已经被系统拒绝

  找到 \source\class\discuz的discuz_application.php 替换

  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;
          }

  替换为：

  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;
          }
