PHP 推送 微信 小程序模版消息的方式，若有不足之处还望指正

form_id 是用户与小程序产生交互时产生的一个 key ，小程序推送模版消息必须要用到它。 获取方法及使用限制另作记录

<?php
namespace common\helpers;

use common\models\ManyCommon;

class WechatMiniPush
{

    public function PushOneMsg($pushInfo)
    {
        $access_token = $this->access_token($pushInfo['app_id'],$pushInfo['app_secret']);
        $url = "https://api.weixin.qq.com/cgi-bin/message/wxopen/template/send?access_token={$access_token}";
        $data = [
            'access_token' => $access_token,
            'touser' => $pushInfo['open_id'],

            'page' => 'pages/tenant/index',
            'form_id' => $pushInfo['form_id'],

        return $data;
    }
