thinkphp在企业微信里面获取用户ID和用户信息

今天帮朋友弄企业微信插件功能，但是有个问题就是，需要获取用户信息，看了一会资料，代码如下：

<?php

namespace addons\loginbg1\controller;

use think\addons\Controller;
use addons\thirdwork\library\Application;

class Index extends Controller {

    protected $app = null;
    private $appId = "wwfc7201d6c5*****";

    public function _initialize() {
        parent::_initialize();
        $config = get_addon_config('thirdwork');
        $this->app = new Application($config);
    }

    public function getAccessToken() {
        $data1 = json_decode(session('AccessToken'));
        if ($data1) {
            if ($data1->expire_time < time()) {
                $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=wwfc7201d6c583****&corpsecret=yTaX2mF2i3sKpi90P5NJ7QW6P9-*****"; 
                $res = $this->https_request($url); 
                $res = json_decode($res); 
                $access_token = $res->access_token;
                if ($access_token) {
                    $data['expire_time'] = time() + 7000; 
                    $data['access_token'] = $access_token;
                    session('AccessToken', json_encode($data));
                }
            } else {
                $access_token = $data1->access_token;
            }
        } else {
            $url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=wwfc7201d6c5834671&corpsecret=yTaX2mF2i3sKpi90P5NJ7QW6P9-W0giskUW_KEaS7N8";
            $res = $this->https_request($url);
            $res = json_decode($res); 
            $access_token = $res->access_token;
            if ($access_token) {
                $data['expire_time'] = time() + 7000;
                $data['access_token'] = $access_token;
                session('AccessToken', json_encode($data));
            }
        }
        return $access_token;
    }

    public function authUser() {


        if (session('UserId')) {


            return session('UserId'); //判断缓存里是否有UserId，如果有直接返回，没有则获取
        } else {

                $accesstoken = $this->getAccessToken(); //调用上面获取access-token的方法
                $code = $_GET['code'];

                $getuser = "https://qyapi.weixin.qq.com/cgi-bin/user/getuserinfo?access_token=" . $accesstoken . "&code=" . $code; //获取userid的url。

                $data = $this->https_request($getuser);
                $data = json_decode($data, true); //将获取到的json格式的数据进行转化。（json_decode（）方法不写后面参数true得到的是对象，写了参数true值得到的是数组）

                if ($data['UserId']) {
                    session('UserId', $data['UserId']);
