官方社区论坛里边已经有人整理出来一部分代码了，但是他没有封装，并且没有写获取openid的方法，所以专门做了个整理，并且有担保支付回调源码
PHP 封装：

<?php

        {

            $this->appid = $appid; //小程序APPID

            $this->appSecret = $appSecret; //小程序的appsecret

        }

        /**

使用方式：

<?php

    $appid = '';  //APPID

    $appSecret = '';   //appsecret

    //①、获取用户openid

    $ksPay = new KspayService($appid,$appSecret);

    $openId = $ksPay->getOpenid($code);      //获取openid

    if(!$openId) exit('获取openid失败');

    // //②、统一下单

    $outTradeNo = '';     //你自己的商品订单号

    $payAmount =  '0.01';         //付款金额，单位:元

    $orderName = '标题';    //订单标题

    $body = '描述';//订单描述

    $notifyUrl = 'https://'.$__SERVER['HTTP_HOST'].'/notify.php';      //付款成功后的回调地址(不要有问号)

    $payTime = time(); //付款时间

    $res = $ksPay->createOrder($orderid,$payAmount,$orderName,$body,$openId,$notifyUrl);

    echo json_encode($res);

?>

回调：

header('Content-type:text/html; Charset=utf-8');

$result = file_get_contents('php://input');

$result = json_decode($result, true);

$kwaisign  = isset($__SERVER['HTTP_KWAISIGN']) ? $__SERVER['HTTP_KWAISIGN'] : '';

if(true){

    //完成你的逻辑

    $orderid = $result['data']['out_order_no'];//订单号

    if($result['data']['status'] == 'SUCCESS'){

        $appSecret = 'z63W9JP6CG6DfkV_7hpKGg';   //appsecret

        $result = json_encode($result);

        $notify = md5($result.$appSecret);//签名



        if($notify == $kwaisign){

            //更新你的数据库



            $res = [

                'result'=>1,

                'message_id'=>$result['message_id']

            ];

            echo json_encode($res);

        }else{

            echo 'Signature error';

        }

    }

}else{

    echo 'pay error';

}

?>
