记录：fastadmin 微信支付(V2)订单实现退款处理，支付金额原路返回
一、在微信商户平台下载证书文件，放在addons\epay\certs 文件夹下，并在epay插件中配置证书位置信息
二、在 addons\epay\library\Service 中增加申请退款代码
/**
* 提交退款订单
* @param array|float $amount 订单金额
* @param array|float $refund_money 退款金额
* @param string $orderid 订单号
* @param string $refund_sn 退款订单号
* @param string $type 支付类型,可选alipay或wechat
* @param string $remark 退款原因
* @param string $notifyurl 通知回调URL
* @param string $returnurl 跳转返回URL
* @param string $method 支付方式
* @return Response|RedirectResponse|Collection
* @throws Exception
*/
public static function submitRefund($amount=null,$refund_money,$orderid,$refund_sn,$type,$remark = null,$notifyurl = null,$returnurl = null,$method = 'app'){
if (!is_array($amount)) {
$params = [
'amount' => $amount,
'refund_money' => $refund_money,
'orderid' => $orderid,
'refund_sn' => $refund_sn,
'type' => $type,
'remark' => $remark,
'notifyurl' => $notifyurl,
'returnurl' => $returnurl,
'method' => $method,
];
} else {
$params = $amount;
}
$amount = isset($params['amount']) ? $params['amount'] : 0;
$refund_money = isset($params['refund_money']) ? $params['refund_money'] : 0;
$orderid = isset($params['orderid']) ? $params['orderid'] : '';
$refund_sn = isset($params['refund_sn']) ? $params['refund_sn'] : '';
$type = isset($params['type']) && in_array($params['type'], ['alipay', 'wechat']) ? $params['type'] : 'wechat';
$remark = isset($params['remark']) ? $params['remark'] : '';
$request = request();
$notifyurl = isset($params['notifyurl']) ? $params['notifyurl'] : $request->root(true) . '/addons/epay/index/' . $type . 'notify';
$returnurl = isset($params['returnurl']) ? $params['returnurl'] : '';
$config = Service::getConfig($type);
$config['notify_url'] = $notifyurl;
$config['return_url'] = $returnurl;
$result = null;
//退款参数
$order_data = [
'out_trade_no' => $orderid//原订单号
];
if ($type == 'wechat') {
//创建支付对象
$pay = Pay::wechat($config);
$total_fee = $amount * 100;
$refund_fee = $refund_money * 100;
$order_data = array_merge($order_data, [
'out_refund_no' => $refund_sn,//退款订单号

}
$result = $pay->refund($order_data);
//使用重写的Response类、RedirectResponse、Collection类
if ($result instanceof \Symfony\Component\HttpFoundation\RedirectResponse) {
$result = RedirectResponse::create($result->getTargetUrl());
} elseif ($result instanceof \Symfony\Component\HttpFoundation\Response) {
$result = Response::create($result->getContent());

$result = Collection::make($result->all());
}
return $result;
}
三、调用退款接口
Db::startTrans();
...
// 调用退款接口
// 异步接收微信支付退款结果通知的回调地址，通知URL必须为外网可访问的url，不允许带参数，公网域名必须为https
$notifyurl = cdnurl('/api/paynotify/refundwxsign'.$refundRow['sign'], true);
try {
$response = \addons\epay\library\Service::submitRefund($orderRow['total_fee'], $refund_money, $refundRow['trade_no'], $refundRow['refund_order_no'], $pay_type='wechat', $refund_reason='用户退款', $notifyurl, $returnurl='', $method='miniapp');
// SUCCESS退款申请接收成功 FAIL 提交业务失败
if($response['return_code'] == 'SUCCESS' && $response['result_code'] == 'SUCCESS'){
$updataData = [
'refund_id' => $response['refund_id'],
'tuikuan_status' => '20', //真实退款状态:0=无,10=未退款,20=退款中,30=退款成功,40=退款关闭,50=退款异常
'tuikuan_time' => time(),
];
}else{
$errorMsg = $response['err_code_des'] ?? $response['return_msg'];
Db::rollback();
throw new Exception('退款申请失败：'.$errorMsg);
}
} catch (\Throwable $th) {
Db::rollback();
throw new Exception('退款申请失败,'.$th);
}
...
// 更新退款状态
$result = $refundRow->allowField(true)->save($updataData);
if($result === false){
Db::rollback();
throw new Exception("抱歉，更新取货状态失败");
}
Db::commit();
回调处理

$order = $this->model->where(['refund_order_no'=>$refund_no])->find();
if (!$order) {
return $this->replyXml('FAIL', '未查询到订单');
}
if($order['tuikuan_status'] == '30'){

}
// 保存退款状态
