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

*/
\'app_id\' => Config::get(\'zhonglian.wechat.AppID\'), // AppID
\'secret\' => Config::get(\'zhonglian.wechat.AppSecret\'), // AppSecret
\'token\' => Config::get(\'zhonglian.wechat.token\'), // Token
\'aes_key\' => Config::get(\'zhonglian.wechat.aes_key\'), // EncodingAESKey，安全模式与兼容模式下请一定要填写！！！
\'response_type\' => \'array\',
];
// 小程序
$this->minConfig = [
\'app_id\' => Config::get(\'zhonglian.minWechat.AppID\'),
\'secret\' => Config::get(\'zhonglian.minWechat.AppSecret\'),

\'response_type\' => \'array\',
\'log\' => [
\'level\' => \'debug\',
\'file\' => __DIR__.\'/wechat.log\',

];
$this->webHost = \'https:://\'.$_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);
