织梦cms内容页如何调用当前页面url地址

if(!function_exists('GetArcUrl')){    function GetArcUrl($id)   {      global $dsql;      $arcRow = $dsql->GetOne("SELECT * FROM dede_archives WHERE `id` = '{$id}'");      $typeRow = $dsql->GetOne("SELECT * FROM dede_arctype WHERE `id` = '{$arcRow['typeid']}'");      $arcurl = GetFileUrl($id,$arcRow['typeid'],$arcRow['senddate'],$arcRow['title'],$arcRow['ismake'],      $arcRow['arcrank'],$typeRow['namerule'],$typeRow['typedir']     ,$arcRow['money'],$arcRow['filename'],$typeRow['moresite'],$typeRow['siteurl'],      $typeRow['sitepath']);      return $arcurl;  }}

然后在内容页通过{dede:field.id function="GetArcUrl(@me)"/}进行调用
