在项目中用到小程序支付，费话不多说上代码
因为我这涉及么微信的很多开发功能 所以我把公共的方法放到的公共类中
WechatPublic
<?php
namespace app\zhonglian\controller\wechat;
use app\BaseController;
use think\facade\Config;
use EasyWeChat\Factory;
use app\zhonglian\controller\ZhonglianPublic;

public $app; //公众号配置

public $wechatPay; //微信支付配置
public function __construct(){
$this->config = [

'response_type' => 'array',
];
// 小程序
$this->minConfig = [
'app_id' => Config::get('zhonglian.minWechat.AppID'),

'response_type' => 'array',
'log' => [
'level' => 'debug',

];
$this->webHost = 'https:://'.$_SERVER['HTTP_HOST']; //站点域名
//微信支付
$this->wechatPay = [
// 必要配置
'app_id' => Config::get('zhonglian.wechatPay.app_id'),
'mch_id' => Config::get('zhonglian.wechatPay.mch_id'),
'key' => Config::get('zhonglian.wechatPay.key'), // API 密钥
// 如需使用敏感接口（如退款、发送红包等）需要配置 API 证书路径(登录商户平台下载 API 证书)
'cert_path' => 'V6/wechatpay/apiclient_cert.pem', // XXX: 绝对路径！！！！
'key_path' => 'V6/wechatpay/apiclient_key.pem', // XXX: 绝对路径！！！！
'notify_url' => $this->webHost.'/zhonglian/zl/pay_notify', // 你也可以在下单时单独设置来想覆盖它
];
$this->app = Factory::officialAccount($this->config);
$this->minApp = Factory::miniProgram($this->minConfig);
$this->pay = Factory::payment($this->wechatPay);
