使用PayPal REST API时出现错误，但在任何地方都找不到解决方案。我正在尝试将用户发送到PayPal，以为会话数组中的指定项目付款。我尝试更改付款方式，付款意向和网址。
$this->setupCurl();
$this->setupPayPal();
$this->payer = new Payer();
$this->details = array();
$this->amount = array();
$this->transaction = array();
$this->redirectUrls = new RedirectUrls();
$this->payment = new Payment();
$this->payer->setPaymentMethod('paypal'); // TODO paypal . credit_card
foreach ($cart as $id => $item) {
$this->details[$id] = new Details();
$this->amount[$id] = new Amount();
$this->transaction[$id] = new Transaction();
$this->details[$id]->setShipping('0.00')
->setTax('0.00')
->setSubtotal(formatMoney($this->products[$id]['price'] * $item['quantity'], '', 2)); // TODO
$this->amount[$id]->setCurrency('AUD')
->setTotal(formatMoney($this->products[$id]['price'] * $item['quantity'], '', 2))
->setDetails($this->details[$id]);
$this->transaction[$id]->setAmount($this->amount[$id])
->setDescription($this->products[$id]['name']); // TODO
}
$this->redirectUrls->setReturnUrl('https://warsentech.com/pay?approved=true')
->setCancelUrl('https://warsentech.com/pay?approved=false');
$this->payment->setIntent('authorize') // TODO sale . buy
->setPayer($this->payer)
->setRedirectUrls($this->redirectUrls)
->setTransactions($this->transaction); // TODO - add transactions into array from the cart items
try {
$this->payment->create($this->paypal);
$hash = md5($this->payment->getId());
$_SESSION['paypal_hash'] = $hash;
if ($this->databaseConnection()) {
$result = $this->db_connection->prepare('INSERT INTO transactions_paypal (user_id, payment_id, hash, complete) VALUES (:user_id, :payment_id, :hash, 0)');
$result->execute([
'user_id' => $_SESSION['user_id'],
'payment_id' => $this->payment->getId(),
'hash' => $hash
]);
}
} catch (Exception $e) {
die(paypalError($e));
}
foreach ($this->payment->getLinks() as $link) {
if ($link->getRel() == 'approval_url') {
$redirectUrl = $link->getHref();
}
}
完整的错误消息：

我建议您解决以下两个问题：
PayPal\Exception\PayPalConnectionException。我们有一种特殊的方法getData()来检索有关该错误的确切详细信息。您可以通过执行以下操作来做到这一点：
try {
$this->payment->create($this->paypal);
$hash = md5($this->payment->getId());
$_SESSION['paypal_hash'] = $hash;
if ($this->databaseConnection()) {
$result = $this->db_connection->prepare('INSERT INTO transactions_paypal (user_id, payment_id, hash, complete) VALUES (:user_id, :payment_id, :hash, 0)');
$result->execute([
'user_id' => $_SESSION['user_id'],
'payment_id' => $this->payment->getId(),
'hash' => $hash
]);
}
} catch (PayPal\Exception\PayPalConnectionException $e) {
echo $e->getData(); // This will print a JSON which has specific details about the error.
die(paypalError($e));
}
如果您希望在集成我们的SDK方面获得帮助，有很多文档可以为您提供帮助。这是您应该关注的最有趣的一个：
特别是，您应该查看该示例，该示例演示了您正在尝试做的事情：http : //paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/CreatePaymentUsingPayPal.html
让我知道这是否有助于您解决所面临的问题。
