   $this->tokenRecord = $this->getTokenTable()->findByKeyString($token->key);
    if ($this->tokenRecord)
    {
      //$this->tokenRecord->setCallbackUrl($request->getParameter('oauth_callback', 'oob'));
      $this->tokenRecord->setCallbackUrl($authRequest->get_parameter('oauth_callback'));
      $this->tokenRecord->setIsActive(false);
      $this->tokenRecord->save();
    }

$request->getParameter では oauthのパラメータは受けられない。
