Question

我使用PayPal REST API时出错，但无法在任何地方找到解决方案。我试图将用户发送到PayPal以支付会话数组中的指定项目。我尝试更改付款方式，意图和网址。

    $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();
        }
    }

我会建议两件事来解决这个问题：

从错误消息中您看到您看到的错误属于PayPal\Exception\PayPalConnectionException类型。我们有一个特殊的方法getData()来检索有关错误的确切详细信息。

你可以通过这样做来做到这一点：

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));
}

如果您希望获得一些有关我们SDK的帮助，那么有很多文档可以帮助您。以下是您应该关注的最有趣的内容：
- 展示每项API操作的示例：http://paypal.github.io/PayPal-PHP-SDK/sample/
- 如何通过一个命令在本地计算机上运行这些示例：https://github.com/paypal/PayPal-PHP-SDK/wiki/Samples
- Wiki页面解释如何开始使用我们的API：https://github.com/paypal/PayPal-PHP-SDK/wiki

具体而言，您应该查看此示例，准确演示您要执行的操作：http://paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/CreatePaymentUsingPayPal.html
