I fixed it use :

//// Add AccessToken for curren session

  function getAccessToken() {
    if ($this->accessToken !== null) {
      return $this->accessToken;
    }

    $this->setAccessToken($this->getApplicationAccessToken());
    $user_access_token = $this->getUserAccessToken();
    if ($user_access_token) {
      $this->setAccessToken($user_access_token);
    }

    return $this->accessToken;
  }

   function getApplicationAccessToken() {
    return $this->appId.'|'.$this->appSecret;
}
