Php 难以使用payum捆绑包管理数据

我正在尝试在我的Symfony2应用程序上通过IPN实现PayPal支付。 我使用PayumBundle和Payum Express签出，我遵循了指令，系统在沙盒环境中运行良好

这是我的控制器：

public function preparePaypalExpressCheckoutPaymentAction($almount)
{

    $paymentName = 'paypall';
    $storage = $this->get('payum')->getStorageForClass(
        'Acme\MyBundle\Entity\PaymentDetails',
        $paymentName
    );


    $paymentDetails = $storage->createModel();
    $paymentDetails['PAYMENTREQUEST_0_CURRENCYCODE'] = 'USD';
    $paymentDetails['PAYMENTREQUEST_0_AMT'] = $almount;
    //Aggiunti
    $paymentDetails['PAYMENTREQUEST_0_AMT'] = $almount;
    $paymentDetails['PAYMENTREQUEST_0_ITEMAMT'] = $almount;
    $paymentDetails['PAYMENTREQUEST_0_PAYMENTACTION'] = "sale";
    $paymentDetails['L_PAYMENTREQUEST_0_NAME0'] = "Recharge";
    $paymentDetails['L_PAYMENTREQUEST_0_QTY0'] = 1;
    $paymentDetails['L_PAYMENTREQUEST_0_AMT0'] = $almount;
    $paymentDetails['NOSHIPPING'] = Api::NOSHIPPING_NOT_DISPLAY_ADDRESS;
    $storage->updateModel($paymentDetails);

    $captureToken = $this->get('payum.security.token_factory')->createCaptureToken(
        $paymentName,
        $paymentDetails,
        'Genia_sepeda_quickpayResponse' // the route to redirect after capture;
    );

    $paymentDetails['INVNUM'] = $paymentDetails->getId();
    $paymentDetails['RETURNURL'] = $captureToken->getTargetUrl();
    $paymentDetails['CANCELURL'] = $captureToken->getTargetUrl();
    $storage->updateModel($paymentDetails);

    return $this->redirect($captureToken->getTargetUrl());

    ///////////////////////////////////////////

}

public function captureDoneAction(Request $request)
{
    $token = $this->get('payum.security.http_request_verifier')->verify($request);

    $payment = $this->get('payum')->getPayment($token->getPaymentName());

    $status = new BinaryMaskStatusRequest($token);
    $payment->execute($status);

    if ($status->isSuccess()) {
        // UPDATE USER DATA HERE
        $this->get('session')->getFlashBag()->set(
            'notice',
            'Successo!. Ricarica effettuata.'
        );
        $em = $this->get('doctrine')->getEntityManager();
        $user= $em->getRepository('AcmeMyBundle:User')->find(1); // JUST FOR TRY
        $credit=$user->getCredit();

        $em->persist($user)
        $em->flush();

    } else if ($status->isPending()) {
        $this->get('session')->getFlashBag()->set(
            'notice',
            'Pagamento In Sospeso. Il credito verrà aggiornato non appena il pagamento avrà successo.'
        );
    } else {
        $this->get('session')->getFlashBag()->set('error', 'Pagamento Fallito.');
    }
    foreach ($this->get('session')->getFlashBag()->get('notice', array()) as $message) {
        echo "<div class='flash-notice'>$message</div>";
    }
    foreach ($this->get('session')->getFlashBag()->get('error', array()) as $message) {
        echo "<div class='flash-notice'>$message</div>";
    }
    return new response("END");
    //return $this->redirect('homepage');
}

通过基本配置，我可以设置付款的总数，并发送到PayPal页面，用户可以登录并传递付款，从控制器正确截获回调并处理CapturedOnAction。 现在，我的问题是添加额外的信息发送到PayPal，它应该返回给我，如用户id、almount等，所有我需要的数据来执行查询，以有效地更新我数据库中的用户信用。

我发现我在理解我的服务器和paypal服务器之间交换的令牌时遗漏了一些东西。发送和获取额外信息的每一个帮助都将不胜感激。

如果我没弄错，您需要一个$paymentDetails模型。如果是这样，请阅读上的答案

您可以扩展此模型“Acme\MyBundle\Entity\PaymentDetails”，并添加与您的用户的关系以及一些不需要paypal但您可以使用的其他字段

顺便说一句，你从控制器那里得到了回音。它不是Symfony方式，将所有html连接到变量，并将其与响应对象一起返回
