我正在努力工作，而 Omnipay 没有提供太多文档。我已经成功地将它用于其他支付网关，但没有用于 Sagepay。我正在尝试将它集成到 CodeIgniter 中，但可以从其他框架中的示例中工作——我快绝望了！

多亏了 github 上的一些巨大帮助（有关线程链接，请参阅我原始帖子中的评论），我现在有一些可行的代码，我将在这里分享，以防将来对其他人有所帮助。

<?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(

        try {

            if ($response->isSuccessful()) :

我昨晚做了一个关于这个的演讲，并将工作演示脚本放在 github 上：

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

SagePay Direct 是一次性操作 - OmniPay 发送交易详细信息并立即获得响应。

SagePay 服务器涉及将用户重定向到 SagePay 网站，以使用他们的卡详细信息授权交易。此 API 使用通知消息，其中 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，以便可以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会做授权。编辑它以使用SagePay\Direct或SagePay\Server查看它是如何工作的。SagePay\Serveris和 that的通知处理程序sagepay-confirm.php最终将用户发送到final.php可以从存储在数据库中的事务中读取结果的位置。

这些脚本都被注释了并且应该是有意义的，但是请随时在此处或在该 github 存储库的问题跟踪器中提出更多关于它们的问题。

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