        $message = '';
        $res=$model->sendMsg();
        if ($res['rest']) {
            return ['status' => 'ok','code'=>$res['code']];
        } else {
            $message = $model->getFirstError('mobile') or $message = '验证码发送失败，请稍后再试！';
        }
        
        return ['status' => 'err', 'message' => $message];
    }
