PHP实现小程序微信支付v3版本退款 以及对退款订单进行查询

PS:本篇文章仅用作对小程序微信支付v3版本的退款流程以及对退款订单进行查询的流程展示,如要用于实际,还请自行修改代码

文章中调用的API_Connect.php 与API_v3Connect.php相对应的链接如下:

API_Connect: /DLH_C/article/details/125912347

API_v3Connect: /DLH_C/article/details/126008134

小程序端JS代码:

v3refund(){wx.request({url: 'http://127.0.0.1:2908/wxPayV3/refundOrder/refundAction.php', //此处修改为你的PHP文件url地址method:'GET',header:{'content-type':'application/json'},data:{'refund':'1', //此处写退款金额,单位为分'total':'1', //此处写订单总金额,单位为分'out_trade_no':'此处写你的商户订单号',},success(res){console.log(res)}})},

PHP类代码:

refundOrder.php

<?phprequire_once ('../API_v3Connect.php');require_once ('../../wxPayV2/API_Connect.php');class refundOrder{/*** 返回请求数据的json格式* @param $out_trade_no :商户订单号* @param $out_refund_no :商户退款订单号* @param $refund :退款金额* @param $total :原订单总金额* @return false|string*/public function refundBody($out_trade_no,$out_refund_no,$refund,$total){$data = array('out_trade_no' => $out_trade_no,'out_refund_no' => $out_refund_no,'notify_url' => '此处写你的回调地址url','amount' => ['refund' => $refund,'total' => $total,'currency' => 'CNY']);return json_encode($data);}/*** 返回商户退款订单号,商家自定义,此处使用日期+时间戳+4位随机数* @return string*/public function getRefundOrder(): string{$basicData = '1234567890';str_shuffle($basicData);$disposeData = substr($basicData,0,4);return date('YmdHis').time().$disposeData;}/*** 返回32位随机字符串* @return string*/public function getNonce_str(): string{$getData = new v2Connect;return $getData -> nonce_str();}/*** 返回参与签名数据的主体* @param $nonce_str :32位随机字符串* @param $requestBody :请求数据主体,json格式* @return string*/public function getRefundSignBody($nonce_str,$requestBody): string{$disposeUrl = '/v3/refund/domestic/refunds';$data = array('POST',$disposeUrl,time(),$nonce_str,$requestBody,'');return join("\n",$data);}/*** 返回退款所需的签名值* @param $data :参与签名的数据主体* @return string*/public function getSignature($data): string{$getData = new API_v3Connect;return $getData -> getSignature($data);}/*** 返回curl请求接口所需的HTTPHEADER* @param $nonce_str :32位随机字符串* @param $signature :退款所需的签名值* @return array*/public function getHeader($nonce_str,$signature): array{$getData = new API_v3Connect;return $getData -> getHeader($nonce_str,$signature);}public function requestRefund($header,$data){$getData = new API_v3Connect;$url = 'https://api.mch./v3/refund/domestic/refunds';return $getData -> curlRequest($url,$header,'POST',$data);}}

PHP调用方法的代码:

refundAction.php

<?phprequire_once ('./refundOrder.php');$getData = new refundOrder;$refund = $_GET['refund']; //接收小程序端发送的退款金额$total = $_GET['total']; //接收小程序端发送的订单总金额$out_trade_no = $_GET['out_trade_no']; //接收小程序端发送的商户订单号$refund = (int)$refund; //将接收到的退款金额转换为int数据类型$total = (int)$total; //将接受的微信订单金额转化为int数据类型var_dump($refund);var_dump($total);$nonce_str = $getData -> getNonce_str(); //获取32位随机字符串$out_refund_no = $getData -> getRefundOrder(); //获取商户退款订单号$requestBody = $getData -> refundBody($out_trade_no,$out_refund_no,$refund,$total); //获取请求数据的主体$signBody = $getData -> getRefundSignBody($nonce_str,$requestBody); //获取参与签名的数据的主体$signature = $getData -> getSignature($signBody); //获取签名值$header = $getData -> getHeader($nonce_str,$signature); //获取curl请求所需要的HTTPHEADER请求头$resultData = $getData -> requestRefund($header,$requestBody); //获取微信退款订单返回的数据echo $resultData;file_put_contents('./refundReturnData.json',$resultData."\n\r",FILE_APPEND); //将微信退款订单返回的数据存入相应的文件中

以上是微信支付v3版本的退款流程,其中部分数据我输出到了相应的文件,是为了看一下返回的数据结构,请按照个人需求自行保留或者删除,其中退款成功时微信返回的JSON数据如下所示

{"amount": {"currency": "CNY","discount_refund": 0,"from": [],"payer_refund": 1,"payer_total": 1,"refund": 1,"settlement_refund": 1,"settlement_total": 1,"total": 1},"channel": "ORIGINAL","create_time": "-07-27T19:10:19+08:00","funds_account": "AVAILABLE","out_refund_no": "07271910181658981234","out_trade_no": "0726165882643607854","promotion_detail": [],"refund_id": "此处显示微信退款订单号","status": "PROCESSING","transaction_id": "420000149707269720733062","user_received_account": "支付用户零钱"}

为了个人隐私,此处我将相关信息隐去,并不影响观看返回数据的数据结构

以下是对微信支付v3版本退款订单的查询

小程序端js代码:

queryRefund(){wx.request({url: 'http://127.0.0.1:2908/wxPayV3/refundOrder/queryRefundOrderAction.php',//此处填写你的PHP文件url地址method:'POST',header:{'content-type':'application/x-www-form-urlencoded'},data:{'out_refund_no':'商户退款单号'},success(res){console.log(res)}})},

PHP类代码

queryRefundOrder.php

<?phprequire_once ('../../wxPayV2/API_Connect.php');require_once ('../API_v3Connect.php');class queryRefundOrder{/*** 返回生成32位随机字符串* @return string*/public function getNonce_str(): string{$getData = new v2Connect;return $getData -> nonce_str();}/*** @param $out_refund_no : 商户退款单号* @param $nonce_str :32位随机字符串* @return string*/public function getSignBody($out_refund_no,$nonce_str): string{$disposeUrl = "/v3/refund/domestic/refunds/$out_refund_no";$data = array('GET',$disposeUrl,time(),$nonce_str,'','');return join("\n",$data);}/*** 返回查询退款订单所需的签名值* @param $data :参与签名的数据主体,即方法getSignBody的返回值* @return string*/public function getSign($data){$getData = new API_v3Connect;return $getData -> getSignature($data);}/*** 返回请求接口所需的HTTPHEADER* @param $nonce_str :32位随机字符串* @param $signature :查询退款订单的签名值* @return array*/public function getHeader($nonce_str,$signature): array{$getData = new API_v3Connect;return $getData -> getHeader($nonce_str,$signature);}/*** 返回curl请求接口微信返回的json数据* @param $out_refund_no :商户退款订单号* @param $header :curl请求接口所需要的HTTPHEADER* @return bool|string*/public function curlRequest($out_refund_no,$header){$getData = new API_v3Connect;$url = "https://api.mch./v3/refund/domestic/refunds/$out_refund_no";return $getData -> curlRequest($url,$header);}}

PHP调用方法的相关代码:

queryRefundOrderAction.php

<?phprequire_once ('./queryRefundOrder.php');$out_refund_no = $_POST['out_refund_no']; //接收来自小程序端的商户退款单号$getData = new QueryRefundOrder;$nonce_str = $getData ->getNonce_str(); //获取32位随机字符串$signBody = $getData -> getSignBody($out_refund_no,$nonce_str); //获取参与签名的数据主体$signature = $getData -> getSign($signBody); //获取查询退款订单所需要的签名值$header = $getData -> getHeader($nonce_str,$signature); //获取curl请求退款订单查询接口的HTTPHEADER$result = $getData -> curlRequest($out_refund_no,$header); //获取curl请求接口后微信返回的数据echo $result;file_put_contents('./queryRefundReturn.json',$result."\n\r",FILE_APPEND); //将微信返回的数据存入向对应的文件

以上就是PHP实现查询小程序微信支付退款订单数据的相关代码

注:退款订单完成时微信就会返回相关的数据,这些数据与你后期通过退款订单查询接口查询到的数据是一样的,所以只要将微信返回的数据做好相关处理,是不需要再次对退款订单进行相关查询的(个人意见,仅供参考)
