Omnipay - Laravel -完成Paypal的就业

Question

我有以下SuccessPayment方法：

    public function getSuccessPayment() {
    $gatewayFactory = new \Omnipay\Common\GatewayFactory;
    $gateway = $gatewayFactory->create('PayPal_Express');
    #Test API Sandbox
    $gateway->setUsername('xxxxxxx.de');
    $gateway->setPassword('xxxxxxxxx');
    $gateway->setSignature('xxxxx.xxxxx.xxxxx.xxxxxxx');
    $gateway->setTestMode(true);

    # FINALIZZZE PAYPAL PAYMENT
    $response = $gateway->completePurchase($this->getApiInfos())->send();
    $data = $response->getData();

    # IF SUCCESSFULLLLLLL
    if($data['ACK'] == 'Success'):
        $order = Order::where('paypalToken',$data['TOKEN'])->first();
        # Set Status
        $order->orderSuccess = 4;
        $order->orderPaid = 1;
        # Set PP ID
        $order->paypalTransactionId = $data['PAYMENTINFO_0_TRANSACTIONID'];
        $order->save();

        # Destroy Cart
        Cart::destroy();

        # Send Confirm Mail
        $this->sendConfirmOrderMail($order->id, Auth::user()->id);

        return View::make('pages.checkout.success', compact(['order','data']));
    endif;
}  

$this->getApiInfos()有凭证和信息，这些凭证和信息将传递到PP，下面是方法：

    public function getApiInfos($order = NULL) {
  return array(
    'amount'=> Cart::total(),
    'cancelUrl' => \URL::route('paypal_cancel_order'),
    'returnUrl' => \URL::route('paypal_return'),
    'description' => 'Your Payment at xxxxxx - Order #',
    'currency' => 'EUR'
  );
}  

看看描述。如何使orderID进入描述，在重定向到Paypal之后，以及在我被重定向回我的页面之后？

我正在失去我的会议和秩序(我猜！)，那么我怎么做呢？

另外，你知道，我如何能够发送航运成本，税收和头图像到PayPal通过Omnipay？

Answer 1

要获取发送给Paypal的事务引用，可以这样做。

$response->getTransactionReference();

关于你问题的后半部分：

PayPal速递网关具有以下设置图像的功能：

$gateway->setHeaderImageUrl()
$gateway->setLogoImageUrl()

所有请求都具有以下功能

$request->setTaxAmount()
$request->setShippingAmount()
$request->setHandlingAmount()
$request->setShippingDiscount()
$request->setInsuranceAmount()
