使用omnipay 通过securepay 处理时出现无效指纹异常

Question

我正在尝试了解使用 Omnipay/SecurePay 的付款流程，但在尝试完成购买时总是出错。

从在线文档中我可以看到，completePurchase 函数应该使用与 purchase 函数相同的参数调用，但是当我调用 completePurchase 时，我收到“无效指纹”异常。

还会抛出这些错误：

Undefined index: merchant in /var/www/vendor/omnipay/securepay/src/Message/DirectPostCompletePurchaseRequest.php on line 28
Undefined index: refid in /var/www/vendor/omnipay/securepay/src/Message/DirectPostCompletePurchaseRequest.php on line 30
Undefined index: timestamp in /var/www/vendor/omnipay/securepay/src/Message/DirectPostCompletePurchaseRequest.php on line 32
Undefined index: summarycode in /var/www/vendor/omnipay/securepay/src/Message/DirectPostCompletePurchaseRequest.php on line 33

我是否错过了添加这些缺失数据的步骤？还是应该在响应中返回这些数据？

代码：

$params = array(
    'amount' =>  $data->payment['amount'] . '.00',
    'currency' => $this->getOptions()->getCurrency(),
    'description' => 'test purchase',
    'transactionId' => '12345',
    'transactionReference' => $data->course['course_code'],
    'returnUrl' => 'http://test.localhost/register/55622/confirmation',
    'cancelUrl' => 'http://test.localhost/register/55622/summary',
    'card'=>$card
 );

$gateway = new DirectPostGateway();
$gateway->setMerchantId( $this->getOptions()->getGateway( $type )['merchant_id'] );
$gateway->setTransactionPassword( $this->getOptions()->getGateway( $type )['password'] );

$gateway->setTestMode( $this->getOptions()->getTestMode() );

$response = $gateway->purchase($params)->send();
var_dump($response->getRedirectData());

$response = $gateway->completePurchase($params)->send();
var_dump($response);
//"Invalid fingerprint" exception thrown

if ($response->isSuccessful()) {
    // payment was successful: update database
    return $response;
} elseif ($response->isRedirect()) {
    // redirect to offsite payment gateway
    if($response->getRedirectData()){
        var_dump($response->getRedirectData());
    } else {
        return $response->redirect();    
    }
    exit;
    return $response->redirect();
} else {
    // payment failed: display message to customer
    // echo $response->getMessage();
    throw new Exception("Error Processing Request", 1);
}

Answer 1

你做事正确。当 SecurePay 返回您的网站时，应该有包含这些参数的 POST 数据，以及确认请求真实性的 fingerprint 参数。

我会在使用 SecurePay 付款时查看您浏览器的“网络”选项卡，并在付款完成（并重定向到您的网站）后检查 HTTP POST 数据。我的猜测是某些 htaccess 或其他脚本正在进行第二次重定向，并同时剥离重要的 POST 数据。

Omnipay 会自动检查 POST 数据，因此无需明确发送。只要您从同一个请求中调用completePurchase()，它就应该正确处理付款。

Securepay 使用端点https://test.securepay.com.au，然后切换到https://test.api.securepay.com.au
