织梦系统二次开发 让采集新闻软件没门

最近在做一个门户网站，想对静态文件名加密
dede 的默认防采集，真的很差；而且对seo也很不利；在网站找了一下也没有找到，只好自己想办法来实现
在include/include/channelunit.helper.php 186行左右找到如下  函数修改

  $articleDir = MfTypedir($typedir);
            $articleRule = strtolower($namerule);
            if($articleRule=='')
            {
                $articleRule = strtolower($GLOBALS['cfg_df_namerule']);
            }
            if($typedir=='')
            {
                $articleDir  = $GLOBALS['cfg_cmspath'].$GLOBALS['cfg_arcdir'];
            }
            $dtime = GetDateMk($timetag);
            list($y, $m, $d) = explode('-', $dtime);
            $arr_rpsource = array('{typedir}','{y}','{m}','{d}','{timestamp}','{aid}','{cc}');
   //my_he 防采集
            $str=md5($aid+'o');
            $aid=substr($str,-6);
            $arr_rpvalues = array($articleDir,$y, $m, $d, $timetag, $aid, dd2char($m.$d.$aid.$y));
            if($filename != '')
            {
                $articleRule = dirname($articleRule).'/'.$filename.$GLOBALS['cfg_df_ext'];
            }
            $articleRule = str_replace($arr_rpsource,$arr_rpvalues,$articleRule);
            if(preg_match("/\{p/", $articleRule))
            {
                $articleRule = str_replace('{pinyin}',GetPinyin($title).'_'.$aid,$articleRule);
                $articleRule = str_replace('{py}',GetPinyin($title,1).'_'.$aid,$articleRule);
            }
            $articleUrl = '/'.preg_replace("/^\//", '', $articleRule);
            if(preg_match("/index\.html/", $articleUrl) && $cfg_arc_dirname=='Y')
            {
                $articleUrl = str_replace('index.html', '', $articleUrl);
            }
            return $articleUrl;
        }
    }
}
