微擎 v2.7.6 后台 微信退款 退款提示 appid参数长度有误 解决方案
涉及文件：
/framework/model/refunt.mod.php
分析原因：
reufnd_wechat_build 这个方法返回的 $refund_param 的appid 和 mch_id 为null 导致
解决办法：
reufnd_wechat_build 这个方法返回 $refund_param ，在return 前 做个判断 如果 appid 为 null 或 mch_id 为null，直接从系统获取到 补上即可
//mark::jonyguan 微擎服务商退款失败问题 - 后台报错 - appid参数长度有误
//在reufnd_wechat_build 这个方法返回 $refund_param 前做如下判断
if(!isset($refund_param['appid']) || !isset($refund_param['mch_id'])){

if (3 == intval($wxpay['switch'])) {
$oauth_account = uni_setting($wxpay['service'], array('payment'));

//这里获取到重新赋值
$refund_param['appid'] = $wxpay['appid'];
