PHP后台实现退款功能（原路原回）

以前对于退款并没有什么研究，因为项目需要用到退款，就研究了下，现在分享出来

PS：后台功能，接口的话可以进行相应的修改

 if($order['payment_type'] == 1)//微信{$refundNo=time().rand(10000,999999).'100001';$wxOrderNo='';$orderNo=$order['order_no'];$result=$this->doRefund($order['pay_money'],$order['pay_money'],$refundNo,$wxOrderNo,$orderNo);if($result===true){if($order_refund !==false){return $data=array('code'=>1);}else{return $data=array('code'=>-1);}}else{echo 'refund fail';}}if($order['payment_type'] == 2)//支付宝{$alipay = new \think\Alipay();$out_trade_no=$order['order_no'];     //订单号$wepay_serial="";     //唯一订单号$totalFee=$order['pay_money'];     //退款金额$array = $alipay ->alipayRefund($out_trade_no,$wepay_serial,$totalFee);if(!empty($array)&&$array == 10000){if($order_refund !==false){return $data=array('code'=>1);}else{return $data=array('code'=>-1);}}}

此处首先判断是微信还是支付宝 ，根据判断原路原回

微信引用方法：

orderrefund()方法中key参数是商户平台的key秘钥，同时还需要商户的俩个证书，放入项目中
支付宝退款方法

 /*** 支付宝退货处理* 退货前提是必须支付成功* @param type $orderId* @return bool*/public function alipayRefund($out_trade_no,$wepay_serial,$totalFee) {Loader::import('.alipay.aop.AopClient', '', '.php');Loader::import('.alipay.aop.request.AlipayTradeRefundRequest', '', '.php');Loader::import('.alipay.aop.SignData', '', '.php');$aop = new \AopClient ();$aop->gatewayUrl = Config::get('alipay')['gatewayUrl'];$aop->appId = Config::get('alipay')['appId'];$aop->rsaPrivateKey = Config::get('alipay')['rsaPrivateKey'];$aop->alipayrsaPublicKey=Config::get('alipay')['alipayrsaPublicKey'];$aop->apiVersion = '1.0';$aop->signType =Config::get('alipay')['signType'];$aop->postCharset='UTF-8';$aop->format=Config::get('alipay')['format'];$request = new \AlipayTradeRefundRequest();$bizcontent = json_encode(['out_trade_no'=>$out_trade_no,'trade_no'=> $wepay_serial,'refund_amount'=> $totalFee,'refund_reason'=>'正常退款']);$request->setBizContent($bizcontent);$result = $aop->execute($request);$responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";$resultCode = $result->$responseNode->code;return $resultCode;}
