PHP PayPal SDK V2 GetExpressCheckoutDetails等效

我正在尝试将我们的Paypal PHP集成转移到使用最新的SDK v2

我们当前的NVP设置只需要2个paypal方法

• SetExpressCheckOut
  • 返回交易令牌（EC-825147XXXXXXXXXX）
• GetExpressCheckoutDetails
  • 返回令牌和PayerID（PayerID:MYT3NHXXXXXX）

我已经设法更新了第一个方法“SetExpressCheckout”， 现在看起来是这样的

$token = $paypal->SetExpressCheckOut($products, $charges);
echo json_encode( array('token'=>$token ) );

$cartTotal = Context::getContext()->cart->getOrderTotal(true);              
echo json_encode($paypal->GetExpressCheckoutDetails($cartTotal));
/*
return(
   'res'     => 'Success'
   'token'   => 'EC-XXXXXXXXXXXX',
   'payerID' => 'MYT3NHXXXXXX'
)
*/

只有2条线，它接收了我们的产品阵列和任何其他运输/处理费用，并返回了交易令牌，但新方法很疯狂，它只返回相同的交易ID

$payer = new \PayPal\Api\Payer();
$payer->setPaymentMethod('paypal');

$amount = new \PayPal\Api\Amount();
$amount->setTotal($cartTotal);
$amount->setCurrency('GBP');

$transaction = new \PayPal\Api\Transaction();
$transaction->setAmount($amount);

$redirectUrls = new \PayPal\Api\RedirectUrls();
$redirectUrls->setReturnUrl("https://www.paypal.com/checkoutnow/error")
                     ->setCancelUrl("https://www.paypal.com/checkoutnow/error");

$payment = new \PayPal\Api\Payment();
$payment->setIntent('authorize')
            ->setPayer($payer)
            ->setTransactions(array($transaction))
            ->setRedirectUrls($redirectUrls);

try {
        // $apiContext, set within our bootstrap file
        $payment->create($apiContext); 

        // need to dig through the response 'approval_url'
        // Locate token in links array, 
        // object "rel" == "approval_url":
        /*
        {
              "href": "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXXXXXX",
              "rel": "approval_url",
              "method": "REDIRECT"
        }
        */
        // looking for token: EC-XXXXXXXXXXXXXXXXX
        $res_data = json_decode($payment, true);
        $urlInfo  = parse_url($res_data['links'][1]['href']);
        parse_str($urlInfo['query'], $queryParams);

        // PASS THE TOKEN BACK TO JS FILE
        echo json_encode( 
                array(
                    'token'=>$queryParams['token'], 
                    'id' => $res_data['id'] 
                ) 
            );              
}
catch (\PayPal\Exception\PayPalConnectionException $ex) {
    // Print detailed information on the exception.
    // HELPFUL FOR DEBUGGING
    echo $ex->getData();
}

但试图复制旧的GetExpressCheckoutDetails以返回payerID被证明是有问题的

我以前的GetExpressCheckoutDetails方法如下

$token = $paypal->SetExpressCheckOut($products, $charges);
echo json_encode( array('token'=>$token ) );

$cartTotal = Context::getContext()->cart->getOrderTotal(true);              
echo json_encode($paypal->GetExpressCheckoutDetails($cartTotal));
/*
return(
   'res'     => 'Success'
   'token'   => 'EC-XXXXXXXXXXXX',
   'payerID' => 'MYT3NHXXXXXX'
)
*/

两行代码&完成了

但我尝试了各种组合，试图获得相同的返回值，但没有成功&我四处寻找一个合适的替代方法来替代这个旧方法

如果有人能告诉我们如何在获得付款后归还payerID，那就太好了

非常感谢

让我试着简化一下，下面的方法将在付款后作为返回url调用

public function paypal_success(){

    $payment = Payment::get($_REQUEST['paymentId'], $this->_api_context);
    $paymentExecution = new \PayPal\Api\PaymentExecution();

    $paymentExecution->setPayerId($_REQUEST['PayerID']);
    $payment->execute($paymentExecution, $this->_api_context);

    //var_dump($_REQUEST);
    echo '<pre>';
    var_dump($payment);
    exit;
}

如果您需要任何进一步的解释，请让我知道。

让我尽量简化，以下方法将在付款后作为返回url调用

public function paypal_success(){

    $payment = Payment::get($_REQUEST['paymentId'], $this->_api_context);
    $paymentExecution = new \PayPal\Api\PaymentExecution();

    $paymentExecution->setPayerId($_REQUEST['PayerID']);
    $payment->execute($paymentExecution, $this->_api_context);

    //var_dump($_REQUEST);
    echo '<pre>';
    var_dump($payment);
    exit;
}
