Magento - 创建新付款方式模块的问题

Question

我正在使用 Magento 1.9.0.1

我正在开发一个添加额外付款方式的自定义扩展程序。 一切似乎都适用于扩展程序 - 付款方式显示正确，但当我尝试选择我的自定义方式“下订单”时出现此错误。

这是我得到的错误：

处理您的请求时出错

出于安全原因，默认情况下禁用异常打印。

错误日志记录号：321152034690

报告如下：

这是我得到的所有内容：/home/sportsdi/public_html/beta/app/code/local/Myname/Mygateway/controllers/PaymentController.php：

<?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();
            }
        }
    }
}

你能帮我找出问题并解决它吗？

提前致谢！

Answer 1

如果您的模块中有任何 echo 语句，那么也会出现此错误，如果找到，请在您的模块 echo 中查找，然后将其删除。

Answer 2

除非您打开输出缓冲，否则使用“echo”语句会导致这种情况。如果还想看回显的结果，放上一行，

ob_start();

相关文件的顶部将为您提供所需的结果。
