支付宝退款接口对接流程PHP语言

作者:互联网

先分享一下支付宝退款的程序源码(我这段代码是通过配置证书而不是字符串秘钥的方式)

sdk下载地址:https://opendocs.alipay.com/open/54/103419#%E8%8E%B7%E5%8F%96%20Alipay%20SDK

    public function refund($refund)
    {
        $appCertPath = THINK_PATH."Library/Vendor/alipay-sdk-PHP-4.9.1/aop/cert/appCertPublicKey_2016071801632148.crt";
        $alipayCertPath = THINK_PATH."Library/Vendor/alipay-sdk-PHP-4.9.1/aop/cert/alipayCertPublicKey_RSA2.crt";
        $rootCertPath = THINK_PATH."Library/Vendor/alipay-sdk-PHP-4.9.1/aop/cert/alipayRootCert.crt";

        require_once THINK_PATH.'Library/Vendor/alipay-sdk-PHP-4.9.1/aop/AopCertClient.php';
        require_once THINK_PATH.'Library/Vendor/alipay-sdk-PHP-4.9.1/aop/request/AlipayTradeRefundRequest.php';

        $aop = new \AopCertClient();
        //网关与证书配置
        $aop->gatewayUrl = 'https://openapi.alipay.com/gateway.do';
        $aop->appId = '应用id';
        $aop->rsaPrivateKey = '用工具生成的RSA私钥,去头去尾去空格';
        $aop->alipayrsaPublicKey=$aop->getPublicKey($alipayCertPath);//'请填写支付宝公钥,一行字符串';
        $aop->isCheckAlipayPublicCert = true;
        $aop->appCertSN = $aop->getCertSN($appCertPath);
        $aop->alipayRootCertSN = $aop->getRootCertSN($rootCertPath);
        //算法编码与格式配置
        $aop->apiVersion = '1.0';
        $aop->signType = 'RSA2';
        $aop->postCharset='UTF-8';
        $aop->format='json';
        //参数内容配置
        $request = new \AlipayTradeRefundRequest ();
        $parameter = array(
            "out_trade_no"=>$this->payInfo['order_id'],//自己商城系统内的订单号,也是原来被付款的订单号
            "refund_amount"=>$this->payInfo['amount'],//退款金额
            "refund_reason"=>"正常退款"
        );
        $request->setBizContent(json_encode($parameter));

        $result = $aop->execute ( $request);

        $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";
        $resultCode = $result->$responseNode->code;
        
     //以下是退款成功后的回调商城对应的操作,与支付宝退款无关
$orderRefund = new OrderRefund(); if(!empty($resultCode)&&$resultCode == 10000){ $orderRefund->returnOkCallback($refund,"成功提交退款至支付宝账户"); } else { $orderRefund->returnErrorCallback($refund,"提交退款至支付宝账户失败"); } }

1.首先你在支付宝平台上要有自己的应用,https://open.alipay.com/platform/developerIndex.htm,没有则创建

$aop->appId 即我们创建的应用id

2.配置秘钥,下载官方工具生成,文档地址:https://opendocs.alipay.com/open/291/105971,生成证书也在该文档中
$aop->rsaPrivateKey

 

3.参数内容中我还有一个订单的详情内容没有配置,只是一个简单的退款,如果你想丰富你的退款商品或者订单信息,查看官方退款接口文档

https://opendocs.alipay.com/apis/api_1/alipay.trade.refund



遇到的坑汇总一下
1.明明信息都是对的,接口返回证书错误,更改了sdk中一处精度的问题,AopCertClient.php的135行
    /**
     * 0x转高精度数字
     * @param $hex
     * @return int|string
     */
    function hex2dec($hex)
    {
        $dec = 0;
        $len = strlen($hex);
        for ($i = 1; $i <= $len; $i++) {
            $dec = bcadd($dec, bcmul(strval(hexdec($hex[$i - 1])), bcpow('16', strval($len - $i))));
        }
        //return round($dec,0);
        return $dec;
    }
