Question

我很难努力去上班，Omnipay也没有多少文档。我已成功将其用于其他支付网关，但未与Sagepay一起使用。我正在尝试将它集成到CodeIgniter中，但可以使用其他框架中的示例 - 我正在绝望！

感谢github上的一些很好的帮助（请参阅我原帖中关于帖子链接的评论），我现在有一些可行的代码，我将在这里分享，以防将来帮助其他人。

<?php 

use Omnipay\Omnipay;

class PaymentGateway  {

    //live details
    private $live_vendor = 'xxx';
    //test details
    private $test_vendor= 'xxx';

    //payment settings
    private $testMode = true;
    private $api_vendor = '';
    private $gateway = null;

    public function __construct()
    {
        parent::__construct();
        //setup api details for test or live
        if ($this->testMode) :
            $this->api_vendor = $this->test_vendor;
        else :
            $this->api_vendor = $this->live_vendor;
        endif;

        //initialise the payment gateway
        $this->gateway = Omnipay::create('SagePay_Server');
        $this->gateway->setVendor($this->api_vendor);
        $this->gateway->setTestMode($this->testMode);



    }


    public function initiate()
    {

        //get order details
        $orderNo = customFunctionToGetOrderNo(); //get the order number from your system however you store and retrieve it

        $params = array(
            'description'=> 'Online order',
            'currency'=> 'GBP',
            'transactionId'=> $orderNo,
            'amount'=> customFunctionToGetOrderTotal($orderNo)
        );


        $customer = customFunctionToGetCustomerDetails($orderNo);

        $params['returnUrl'] = '/payment-gateway-process/' . $orderNo .  '/'; //this is the Sagepay NotificationURL

        $params['card'] = array(
            'firstName' => $customer['billing_firstname'],

            'shippingCity' => $customer['delivery_town'],
            'shippingPostcode' => $customer['delivery_postcode'],
            'shippingCountry' => $customer['delivery_country']
        );


        try {
            $response = $this->gateway->purchase($params)->send();


            if ($response->isSuccessful()) :

                //not using this part

            elseif ($response->isRedirect()) :

                $reference = $response->getTransactionReference();

        } catch (\Exception $e) {

            //do something with this if an error has occurred
            echo 'Sorry, there was an error processing your payment. Please try again later.';
        }



    }


    public function processPayment($orderNo)
    {

            //encrypt it to stop anyone being able to view other orders
            $encodeOrderNo = customFunctionToEncodeOrderNo($orderNo);
            $response->confirm('/payment-gateway-response/' . $encodeOrderNo);

        } catch(InvalidResponseException $e) {
            // Send "INVALID" response back to SagePay.
            $request = $this->gateway->completePurchase(array());
            $response = new \Omnipay\SagePay\Message\ServerCompleteAuthorizeResponse($request, array());

            customFunctionToSaveMessage($orderNo, array('gateway_response' => $response->getMessage()));

            redirect('/payment-error-response/');

    }

    {
        $orderNo = customFunctionToDecode($encodedOrderNo);
        $sessionOrderNo = customFunctionToGetOrderNo();

        endif;
        $status = customFunctionToGetOrderStatus($orderNo);

我昨晚做了一个关于这个问题的演讲，并把工作演示脚本放在github上：

https://github.com/academe/OmniPay-SagePay-Demo

SagePay Direct是一次性行动 - OmniPay会发送交易详情并立即得到回复。

SagePay Server涉及将用户重定向到SagePay网站，以使用其卡详细信息授权交易。此API使用通知消息，SagePay将使用授权结果直接调用您的应用程序。这发生在用户会话之外，因此需要将事务存储在数据库中，以便在两个事务之间共享。

所有这些都在上面链接的脚本中。 authorize.php将执行授权。修改为使用SagePay\Direct或SagePay\Server查看其工作原理。 SagePay\Server的通知处理程序为sagepay-confirm.php，最终将用户发送到final.php，其中可以从存储在数据库中的事务中读取结果。

脚本都是注释的，应该是有意义的，但可以在这里或在github存储库的问题跟踪器中询问有关它们的更多问题。

我没有尝试使用3D-Secure SagePay\Direct。这些脚本可能需要一些修改来支持它，假设组合是一个东西。

有没有人有Omnipay和Sagepay Server或Sagepay Direct（带有3D Secure）的工作示例？
