发送消息-配置app_id

$user_id = $curr_workitem["creater_id"];
$user_name = g('dao_user') -> get_by_id($user_id);
$msg_title=$this -> AppCName."查阅提醒";
$msg_desc = $this -> AppCName."："."您发起的《".$curr_workitem["formsetinst_name"]."》流程已被查阅且直接关闭。";
$msg_url = MAIN_DYNAMIC_DOMAIN.'index.php?model='.$this -> AppName.'&m=index&a=dealList&corpurl=' . $_SESSION[SESSION_VISIT_CORP_URL];

$content = '收到了【' . $user_name['name'] . '】的信息';

$to_users = array($user_id);
g('api_nmsg') -> init($this -> com_id, 'process', $_SESSION[SESSION_VISIT_CORP_URL]);
$send_flag = g('api_nmsg') -> send_text($content, array(), $to_users);
if (!$send_flag) {
parent::echo_err($this -> busy, '发送消息失败');
}

采用这种方式发送消息，需要配置app_id才能发送成功
