php 支付宝支付接口

我用的官方sdk    https://docs.open.alipay.com/270/106291/

直接aop文件夹放到PHP环境

配置 AopClient.php这个文件秘钥和公钥搞了一会这个一定要配置正确

    //应用ID
    public $appId
    //私钥值
    public $rsaPrivateKey
    //支付宝公钥
    public $alipayrsaPublicKey

然后我写了一个 alipay_functions.php放在aop同级目录写了退款和查询订单两个函数代码如下

    <?php
    //获取支付编号支付信息
    function alipay_get_pay_info($trade_no){
       include(\'aop/AopClient.php\');
       include(\'aop/SignData.php\');
       include(\'aop/request/AlipayTradeQueryRequest.php\');
       $aop = new AopClient;
       $request = new AlipayTradeQueryRequest();
       $bizcontent = json_encode([\'trade_no\'=>$trade_no,]);
       $request->setBizContent($bizcontent);
       $result = $aop->execute($request);
       var_dump($result);
    }

    //订单退款
    function alipay_refund($trade_no,$order_amount){
       include(\'aop/AopClient.php\');
       include(\'aop/SignData.php\');
       include(\'aop/request/AlipayTradeRefundRequest.php\');
       $aop = new AopClient;
       $request = new AlipayTradeRefundRequest();
       $bizcontent = json_encode([\'trade_no\'=>$trade_no,\'refund_amount\'=>$order_amount]);
       $request->setBizContent($bizcontent);
       $result = $aop->execute($request);
       //var_dump($result);
    }

添加对账单查询函数

    //对账单账单时间：日账单格式为yyyy-MM-dd，月账单格式为yyyy-MM。
    function alipay_bills($date){
       include(\'aop/AopClient.php\');
       include(\'aop/SignData.php\');
       include(\'aop/request/AlipayDataDataserviceBillDownloadurlQueryRequest.php\');
       $aop = new AopClient;
       $request = new AlipayDataDataserviceBillDownloadurlQueryRequest();
       $bizcontent = json_encode([\'bill_type\'=>\'trade\',\'bill_date\'=>$date]);
       $request->setBizContent($bizcontent);
       $result = $aop->execute($request);
       header("Location: ".$result->alipay_data_dataservice_bill_downloadurl_query_response->bill_download_url);
    }

然后项目内调用

    include(ROOT_PATH.\'666plugins/alipay_functions.php\');
    alipay_refund($order[\'transaction_id\'],$order[\'order_amount\']);

问题 1   如果原有项目中有 function encrypt() 这个函数会报错函数名冲突

打开 AopEncrypt.php 修改函数名 encrypt 为 encrypt_aop

        打开 AopClient.php    修改两处调用函数的地方
