PAYPAL PHP SDK不重定向？

Question

我正在尝试使用PayPal的PHP SDK进行测试交易，并通过composer安装了它。 问题是脚本执行完后，我没有重定向到PayPal网关，当我将标头函数与$ approvalurl一起使用时，我重定向到了PayPal登录名，但是数据没有提交（我最终在我卖家帐户的PayPal登录网站，但没有传输任何价格或产品信息）

知道有什么问题吗？ 这是我的脚本的样子：

<?php 

ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
error_reporting(-1);
// Autoload SDK package for composer based installations
require 'vendor/autoload.php';

$apiContext = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential(
       'api_key',
       'api_secret'
    )
);

$apiContext->setConfig(
    array(
       'log.LogEnabled' => true,
       'log.FileName' => 'PayPal.log',
       'log.LogLevel' => 'DEBUG'
    )
);

use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Api\Transaction;

// Create new payer and method
$payer = new Payer();
$payer->setPaymentMethod("paypal");

// Set redirect urls
$redirectUrls = new RedirectUrls();
$redirectUrls->setReturnUrl('http://localhost:3000/process.php')
->setCancelUrl('http://localhost:3000/cancel.php');

// Set payment amount
$amount = new Amount();
$amount->setCurrency("USD")
->setTotal(10);

// Set transaction object
$transaction = new Transaction();
$transaction->setAmount($amount)
->setDescription("Payment description");

// Create the full payment object
$payment = new Payment();
$payment->setIntent('sale')
->setPayer($payer)
->setRedirectUrls($redirectUrls)
->setTransactions(array($transaction));

// Create payment with valid API context
try {
    $payment->create($apiContext);
    //echo "Payment Id is " . $payment->getId();
    // Get PayPal redirect URL and redirect user
    $approvalUrl = $payment->getApprovalLink();

    // REDIRECT USER TO $approvalUrl
    header("Location: $approvalUrl");
} catch (PayPal\Exception\PayPalConnectionException $ex) {
    echo 'Exception abgefangen: ', $ex->getData(), "\n";
    echo $ex->getCode();
    echo $ex->getData();
    die($ex);
} catch (Exception $ex) {
    die($ex);
}

$approvalUrl = $payment->getApprovalLink();

return $payment;
?>
