xml - 使用 POST 身份验证重定向到第三方支付网关

Question

我在 Magento 中为自定义付款方式提供了一个几乎完整的解决方案。我遵循 [this] http://www.junaidbhura.com/how-to-make-a-custom-magento-payment-extension-for-an-external-gateway/优秀教程，但我现在遇到身份验证问题。

我联系了网关，一位 IT 代表告诉我，我必须将正确的值发布到网关以进行身份​​验证。这些值也必须以 XML 格式发送：

测试模式用户名：###### 测试模式密码：###### 测试模式商家ID：##### 测试模式终端ID：##### BIN = ######1

我在网关模块中创建了一个带有正确字段的 system.xml：

<?xml version="1.0"?>

我不确定验证到 PaymentController.php 所需的 POST 值的实现

<?php

class Myname_Mygateway_PaymentController extends Mage_Core_Controller_Front_Action {
    // The redirect action is triggered when someone places an order
    public function redirectAction() {
        $this->loadLayout();
        $block = $this->getLayout()->createBlock('Mage_Core_Block_Template','mygateway',array('template' => 'mygateway/redirect.phtml'));
        $this->getLayout()->getBlock('content')->append($block);
        $this->renderLayout();
    }

    // The response action is triggered when your gateway sends back a response after processing the customer's payment
    public function responseAction() {
        if($this->getRequest()->isPost()) {

            /*
            /* Your gateway's code to make sure the reponse you
            /* just got is from the gatway and not from some weirdo.
            /* This generally has some checksum or other checks,
            /* and is provided by the gateway.
            /* For now, we assume that the gateway's response is valid
            */

            $validated = true;
            $orderId = '123'; // Generally sent by gateway

            if($validated) {
                // Payment was successful, so update the order's state, send order email and move to the success page
                $order = Mage::getModel('sales/order');
                $order->loadByIncrementId($orderId);
                $order->setState(Mage_Sales_Model_Order::STATE_PROCESSING, true, 'Gateway has authorized the payment.');

                $order->sendNewOrderEmail();
                $order->setEmailSent(true);

                $order->save();

                Mage::getSingleton('checkout/session')->unsQuoteId();

                Mage_Core_Controller_Varien_Action::_redirect('checkout/onepage/success', array('_secure'=>true));
            }
            else {
                // There is a problem in the response we got
                $this->cancelAction();
                Mage_Core_Controller_Varien_Action::_redirect('checkout/onepage/failure', array('_secure'=>true));
            }
        }
        else
            Mage_Core_Controller_Varien_Action::_redirect('');
    }

    // The cancel action is triggered when an order is to be cancelled
    public function cancelAction() {
        if (Mage::getSingleton('checkout/session')->getLastRealOrderId()) {
            $order = Mage::getModel('sales/order')->loadByIncrementId(Mage::getSingleton('checkout/session')->getLastRealOrderId());
            if($order->getId()) {
                // Flag the order as 'cancelled' and save it
                $order->cancel()->setState(Mage_Sales_Model_Order::STATE_CANCELED, true, 'Gateway has declined the payment.')->save();
            }
        }
    }
}

最后是重定向的表单，即redirect.phtml

<?php
// Retrieve order
$_order = new Mage_Sales_Model_Order();
$orderId = Mage::getSingleton('checkout/session')->getLastRealOrderId();
$_order->loadByIncrementId($orderId);
?>
<form name="mygatewayform" method="post" action="http://www.gateway.com/the_url_they_gave_me">
    <input type="hidden" name="orderid" value="<?php echo $orderId; ?>">
    <input type="hidden" name="grandtotal" value="<?php echo $_order->getBaseGrandTotal(); ?>">
</form>
<script type="text/javascript">
document.mygatewayform.submit();
</script>

我能够运行测试订单，但由于 IP 记录，网关只收到了我的订单，而且格式不正确。在发帖之前，我已经在 Magento 论坛和 Google 上搜索了将近三周，但我没有找到任何解决方案。网关无法提供帮助，因为也没有 Magento 集成手册。

如果不是太麻烦，我将非常感谢您的帮助...

Answer 1

您的以下说明用于创建将重定向到第三方网关的付款。

The URL that the payment gateway needs to redirect to on your web site after processing the customer’s payment (based on the naming we’ve used in this example) should be: http://www.yourwebsite.com/mygateway/payment/response .

完成您要完成的工作的最佳方法是遵循此http://www.excellencemagentoblog.com/magento-create-custom-payment-method-api-based。

另见

/app/code/core/Mage/Paygate/Model/Authorizenet.php

//create xml and send info to gateway
private function callApi(Varien_Object $payment, $amount,$type){

    //call your authorize api here, incase of error throw exception.
    //only example code written below to show flow of code

    /*
     $order = $payment->getOrder();
