如何向社交引擎添加自定义支付网关

Question

我需要在我们的公司网站上集成一个新的支付网关，该网站基于社交引擎。这个CMS 有一个扩展名为Advanced Payment Gateways，它允许集成新的网关。事实上，它会获取您的网关名称并生成一个压缩为文件的骨架结构，因此您可以解压缩并上传到您的服务器，从而与应用程序目录合并。

我将解释如何在没有社交引擎的情况下实现我的网关，我希望有人能告诉我如何将它整合到社交引擎中。

1. 首先我连接到我的PSP 服务：

   $client = new nusoap_client('https://example.com/pgwchannel/services/pgw?wsdl');
   

2. 我在一个数组中准备了以下参数发送到bpPayRequest：

   $parameters = array(
       'terminalId' => $terminalId,
       'userName' => $userName,
       'userPassword' => $userPassword,
       'orderId' => $orderId,
       'amount' => $amount,
       'localDate' => $localDate,
       'localTime' => $localTime,
       'additionalData' => $additionalData,
       'callBackUrl' => $callBackUrl,
       'payerId' => $payerId);
   
   // Call the SOAP method
   $result = $client->call('bpPayRequest', $parameters, $namespace);
   

3. 如果支付请求被接受，结果是一个逗号分隔的字符串，第一个元素是0。
   然后我们可以将第二个元素（参考ID）发送到付款 通过POST方法网关如下：

   echo "<script language='javascript' type='text/javascript'>postRefId('" . $res[1] . "');</script>";
   
   <script language="javascript" type="text/javascript">    
       function postRefId (refIdValue) {
           var form = document.createElement("form");
           form.setAttribute("method", "POST");
           form.setAttribute("action", "https://example.com/pgwchannel/startpay");         
           form.setAttribute("target", "_self");
           var hiddenField = document.createElement("input");              
           hiddenField.setAttribute("name", "RefId");
           hiddenField.setAttribute("value", refIdValue);
           form.appendChild(hiddenField);
   
           document.body.appendChild(form);         
           form.submit();
           document.body.removeChild(form);
       }
       </script>
   

4. 网关将通过POST方法将以下参数返回给我们在支付请求中提供的回调URL：
   RefId（参考id在前面步骤中生成）
   ResCode（支付结果：0表示成功）
   saleOrderId（支付请求时传递的订单id）
   SaleReferenceId（销售参考代码由PSP提供给商家）

5. 如果上一步的ResCode是0，那么我们需要通过调用bpVerifyRequest并传入以下参数来验证支付，否则支付将被取消。

    $parameters = array(
       'terminalId' => $terminalId,
       'userName' => $userName,
       'userPassword' => $userPassword,
       'orderId' => $orderId,
       'saleOrderId' => $verifySaleOrderId,
       'saleReferenceId' => $verifySaleReferenceId);
   
   // Call the SOAP method
   $result = $client->call('bpVerifyRequest', $parameters, $namespace);
   

6. 如果bpVerifyRequest的结果为零，则支付确定，商家必须提供购买的商品或服务。但是，有一个可选方法bpSettleRequest，用于请求结算。调用如下：

    $parameters = array(
        'terminalId' => $terminalId,
        'userName' => $userName,
        'userPassword' => $userPassword,
        'orderId' => $orderId,
        'saleOrderId' => $settleSaleOrderId,
        'saleReferenceId' => $settleSaleReferenceId);

    // Call the SOAP method
    $result = $client->call('bpSettleRequest', $parameters, $namespace);

我对支付网关插件中的默认网关感到困惑，例如PayPal、Stripe、2Checkout 等。我如何将此代码逻辑合并到新创建的网关框架中？ （结构如下图）：

default.php
callback.php

Answer 1

我通过在Engine_Payment_Gateway_MyGateway 类中添加支付代码解决了这个问题：

一旦用户在 SocialEngine 页面上确认他们想要支付，就会调用上述类中的方法processTransaction()，并将用户重定向到 PSP 的支付安全页面。一旦他们完成支付，即支付成功或失败或取消交易，他们的 PSP 页面会将他们重定向到我们之前作为 callBackUrl 参数发送给它的页面。在那里，您将收到 PSP 特定的参数，这些参数可以帮助您确定付款是否成功，并通过另一个 SOAP 调用询问 PSP 以确认付款，然后可选地要求它结算（尽快将钱存入卖家账户）：

添加到 processTransaction()：

        $data = array();
        $rawData = $transaction->getRawData();

        //Save order ID for later
        $this->_orderId = $rawData['vendor_order_id'];
        $this->_grandTotal = $rawData['AMT'];


        $client = new nusoap_client('https://example.com/pgwchannel/services/pgw?wsdl');
        $namespace = 'http://interfaces.core.sw.example.com/';


        // Check for an error
        $err = $client->getError();
        if ($err) {
            echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
            die();
        }


        /* Set variables */

//Get price from SEAO 
//$order_ids = Engine_Api::_()->getDbTable('orders','sitestoreproduct')->getOrderIds($this->parent_id);
//$price = Engine_Api::_()->getDbTable('orders','sitestoreproduct')->getGrandTotal($this->parent_id);


        $terminalId = '1111111';
        $userName = 'username';
        $userPassword = '1111111';
        $orderId = $rawData['vendor_order_id'];

        $amount = $rawData['AMT'];
        $localDate = date("Y") . date("m") . date("d");
        $localTime = date("h") . date("i") . date("s");
        $additionalData = $rawData['return_url'];
        $callBackUrl = 'https://example.com/pgateway/pay/callback';
        $payerId = '0';







        /* Define parameters array   */

        $parameters = array(
            'terminalId' => $terminalId,
            'userName' => $userName,
            'userPassword' => $userPassword,
            'orderId' => $orderId,
            'amount' => $amount,
            'localDate' => $localDate,
            'localTime' => $localTime,
            'additionalData' => $additionalData,
            'callBackUrl' => $callBackUrl,
            'payerId' => $payerId
        );



        $result = $client->call('bpPayRequest', $parameters, $namespace);



        if ($client->fault) {
            echo '<h2>Fault</h2><pre>';
            print_r($result);
            echo '</pre>';
            die();
        } else { //Check for errors
            $error = $client->getError();
            if ($error) {
                echo "An error occurred: ";
                print_r($error);
                die();
            } else {
                //break the code
                $resultSegmts = explode(',', $result);
                $ResCode = $resultSegmts [0];


                if ($ResCode == "0") {
                    //Notify admin of the order                    
                    echo '<h3>Redirecting you to the payment page. Please wait...</h3><br/>';
                    echo '<script language="javascript" type="text/javascript">
                      postRefId("' . $resultSegmts[1] . '");
                    </script>';
                } elseif ($ResCode == "25") {
                    echo "<h3>Purchase successful</h3>";
                } else {
                    echo "<h3>PSP response is: $ResCode</h3>";
                } 
            }
        }

添加到您的回调操作：

    $this->view->message = 'This is callback action for PayController';
    $RefId = $_POST['RefId'];
    $ResCode = $_POST['ResCode'];
    $saleOrderId = $_POST['SaleOrderId'];
    $saleReferenceId = $_POST['SaleReferenceId'];

    $this->_orderId = $saleOrderId;

        $this->view->RefId = $RefId;
        $this->view->saleOlderId = $saleOrderId;
        $this->view->saleReferenceId = $saleReferenceId;
    }
    if ($ResCode == "0") {
        try {
            $client = new nusoap_client('https://example.com/pgwchannel/services/pgw?wsdl');
        } catch (Exception $e) {
            die($e->getMessage());
        }

        $namespace = 'http://interfaces.core.sw.example.com/';
        $terminalId = "111111";
        $userName = "username";
        $userPassword = "11111111";


        $parameters = array(
            'terminalId' => $terminalId,
            'userName' => $userName,
            'userPassword' => $userPassword,
            'orderId' => $saleOrderId,
            'saleOrderId' => $saleOrderId,
            'saleReferenceId' => $saleReferenceId
        );
        $resVerify = $client->call('bpVerifyRequest', $parameters, $namespace);



        if ($resVerify->fault) { //Check for fault 
            echo "<h1>Fault: </h1>";
            print_r($result);
            die();
        } else { //No fault: check for errors now 
            $err = $client->getError();
            if ($err) {
                echo "<h1>Error: " . $err . " </h1>";
            } else {
                if ($resVerify == "0") {//Check verification response: if 0, then purchase was successful. 
                    echo "<div class='center content green'>Payment successful. Thank you for your order.</div>";
                    $this->view->message = $this->_translate('Thanks for your purchase.');
                    $this->dbSave(); //update database table
                } else
                    echo "<script language='javascript' type='text/javascript'>alert(    'Verification Response: " . $resVerify . "');</script>";
            }
        }

        //Note that we need to send bpSettleRequest to PSP service to request settlement once we have verified the payment 
        if ($resVerify == "0") {
            // Update table, Save RefId
            //Create parameters array for settle
            $this->sendEmail();
            $this->sendSms();

            $resSettle = $client->call('bpSettleRequest', $parameters, $namespace);
            //Check for fault 
            if ($resSettle->fault) {
                echo "<h1>Fault: </h1><br/><pre>";
                print_r($resSettle);
                echo "</pre>";
                die();
            } else { //No fault in bpSettleRequest result 
                $err = $client->getError();
                if ($err) {
                    echo "<h1>Error: </h1><pre>" . $err . "</pre>";
                    die();
                } else {
                    if ($resSettle == "0" || $resSettle == "45") {//Settle request successful 
                        // echo "<script language='javascript' type='text/javascript'>alert('Payment successful');</script>";
                    }
                }
            }
