Integration von Omnipay mit PayPal Express Checkout [symfony2]

Question

Ich versuche, ominipay mit PayPal Express Checkout in meiner Website zu integrieren. Ich habe eine Tabelle commande (Auftrag in Englisch), wo ich die Referenz, das Datum, user_id, commande => speichern [commande speichert: priceTTC, priceHT, Adresse, Menge, Token].

Wenn der Benutzer klicken Sie auf den Button Pay ich diesen Fehler haben:

Controller "FLY\BookingsBundle\Controller\PayController::postPaymentAction" for URI "/payment/2" is not callable.

Das ist mein validation.html.twig

<form action="{{ path('postPayment', { 'id' : commande.id }) }}" 
    method="POST"/> 
    <input name="token" type="hidden" value="{{ commande.commande.token }}" /> 
    <input name="price" type="hidden" value="{{ commande.commande.priceTTC }}" /> 
    <input name="date" type="hidden" value="{{ commande.date|date('dmyhms') }}" /> 
    <button type="submit" class="btn btn-success pull-right">Pay</button> 
    </form> 

routing.yml

postPayment: 
    pattern: /payment/{id} 
    defaults: { _controller: FLYBookingsBundle:Pay:postPayment } 

getSuccessPayment: 
    pattern: /success/{id} 
    defaults: { _controller: FLYBookingsBundle:Pay:getSuccessPayment } 

PayController.php

class PayController extends Controller 
{ 

    public function postPayment (Commandes $commande) 
    { 
     $params = array(
      'cancelUrl' => 'here you should place the url to which the users will be redirected if they cancel the payment', 
      'returnUrl' => 'here you should place the url to which the response of PayPal will be proceeded', // in your case    // you have registered in the routes 'payment_success' 
      'amount' => $commande->get('priceTTC'), 
     ); 

     session()->put('params', $params); // here you save the params to the session so you can use them later. 
     session()->save(); 

     $gateway = Omnipay::create('PayPal_Express'); 
     $gateway->setUsername('xxxxxxxxx-facilitator_api1.gmail.com'); // here you should place the email of the business sandbox account 
     $gateway->setPassword('xxxxxxxxxxxxxx'); // here will be the password for the account 
     $gateway->setSignature('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'); // and the signature for the account 
     $gateway->setTestMode(true); // set it to true when you develop and when you go to production to false 
     $response = $gateway->purchase($params)->send(); // here you send details to PayPal 

     if ($response->isRedirect()) { 
      // redirect to offsite payment gateway 
      $response->redirect(); 
     } 
     else { 
      // payment failed: display message to customer 
      echo $response->getMessage(); 
     } 
    } 

.

public function getSuccessPayment (Auth $auth, Transaction $transaction) 
    { 
     $gateway = Omnipay::create('PayPal_Express'); 
     $gateway->setUsername('xxxxxxxxxxx-facilitator_api1.gmail.com\''); // here you should place the email of the business sandbox account 
     $gateway->setPassword('xxxxxxxxxxxxxxxx'); // here will be the password for the account 
     $gateway->setSignature('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'); // and the signature for the account 
     $gateway->setTestMode(true); 
     $params = session()->get('params'); 
     $response = $gateway->completePurchase($params)->send(); 
     $paypalResponse = $response->getData(); // this is the raw response object 

     if(isset($paypalResponse['PAYMENTINFO_0_ACK']) && $paypalResponse['PAYMENTINFO_0_ACK'] === 'Success') { 
      // here you process the response. Save to database ... 

     } 
     else { 
      // Failed transaction ... 
     } 
    } 
}

Eine aufrufbare Symfony-Controller-Methode sollte mit dem Action-Wort enden.

public function postPayment(...) ->public function postPaymentAction(...)

Dann sind einige Ihrer Controller-Methoden nicht symfony-gültig, sie scheinen Laravel Basis statt.

// Laravel 
session()->put('params', $params); // here you save the params to the session so you can use them later. 
session()->save(); 

--> 
// Symfony 

use Symfony\Component\HttpFoundation\Request; 

public function postPaymentAction(Commandes $commande, Request $request) 

$request->getSession(); // The request should be incldued as an action parameter 
$session->set('params', $params); 

Dann über die Verwendung von Omnipay selbst, würde ich sagen, dass eine 3rd-Party-Bibliothek in einem Symfony Controller eine schreckliche Praxis.

Ich empfehle Ihnen, stattdessen einen Dienst zu verwenden und Ihre Anmeldeinformationen aus der Konfiguration (möglicherweise Parameter) zu übergeben.

http://symfony.com/doc/current/service_container.html

// Direct, bad practice 
$gateway = Omnipay::create('PayPal_Express'); 
$gateway->setUsername('xxxxxxxxx-facilitator_api1.gmail.com'); // here you should place the email of the business sandbox account 
$gateway->setPassword('xxxxxxxxxxxxxx'); // here will be the password for the account 
$gateway->setSignature('xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'); // and the signature for the account 
$gateway->setTestMode(true); // set it to true when you develop and when you go to production to false 

$response = $gateway->purchase($params)->send(); // here you send details to PayPal 

Sie sogar bereits ein Bündel 3rd-Party haben, das zu tun:

https://github.com/colinodell/omnipay-bundle

// Using a Service to get a full-configured gateway 
$gateway = $this->get('omnipay')->getDefaultGateway(); 

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

Sie auch die HTTP-Methoden in Ihrem Router Datei sperren könnte, auch Wenn es optional ist:

postPayment: 
    pattern: /payment/{id} 
    method: POST 
    defaults: { _controller: FLYBookingsBundle:Pay:postPayment } 

getSuccessPayment: 
    pattern: /success/{id} 
    method: GET 
    defaults: { _controller: FLYBookingsBundle:Pay:getSuccessPayment }
