PayPal SDK产品数组返回一个错误 - PayPal SDK Array of products return an error

PayPal SDK Array of products return an error

我正在学习PayPal SDK，当我第一次使用一个产品时，它工作得很好。现在我要处理一组产品。代码

$paypal = new ApiContext(
        new OAuthTokenCredential(
            '...',
            '...'
        )
    );
    $payer = new Payer();
    $payer->setPaymentMethod('paypal');
    $shipping = 2;
    $totalPriceWithShipping = 0;
    $totalPriceWithoutShipping = 0;

    $items = [];
    foreach(Controller::getData('productsInCart') as $product)
    {
        $totalPriceWithShipping += ($product->price + $shipping);
        $totalPriceWithoutShipping += $product->price;
        $item = new Item();
        $item->setName($product->name)
            ->setPrice($product->price)
            ->setCurrency('USD')
            ->setQuantity(1);
        $items[] = $item;
    }
    $itemList = new ItemList();
    $itemList->setItems($items);
    $details = new Details();
    $details->setShipping($shipping)
            ->setSubtotal($totalPriceWithoutShipping);

    $amount = new Amount();
    $amount->setCurrency('USD')
        ->setTotal($totalPriceWithShipping)
        ->setDetails($details);

    $transaction = new Transaction();
    $transaction->setItemList($itemList)
                ->setAmount($amount)
                ->setDescription('Your Order from Online Shop')
                ->setInvoiceNumber(uniqid());
    $redirectUrls = new RedirectUrls();
    $redirectUrls->setReturnUrl('...')
                ->setCancelUrl('...');
    $payment = new Payment();
    $payment->setIntent('sale')
            ->setPayer($payer)
            ->setRedirectUrls($redirectUrls)
            ->setTransactions([$transaction]);
    try {
        $payment->create($paypal);
    }
    catch(Exception $e) {
        die($e->getTrace());
    }
   die($payment->getApprovalLink());

但是我得到了这个错误:

致命错误:在C:'dev'htdocs'Shop'vendor' PayPal' rest-api-sdk-php'lib'PayPal'Core'PayPalHttpConnection.php:180 Stack trace: #0 C:'dev'htdocs'Shop'vendor' PayPal' rest-api-sdk-php'lib'PayPal'Transport'PayPalRestCall.php(74)中未捕获异常'PayPal' exception 'PayPalConnectionException'与消息'访问https://api.sandbox.paypal.com/v1/payments/payment时获得Http响应代码400 ':PayPal'Core'PayPalHttpConnection->execute('{"intent":"sale…')#1 C:'dev'htdocs'Shop'vendor' PayPal' rest-api-sdk-php'lib'PayPal'Common'PayPalResourceModel.php(102): PayPal'Transport'PayPalRestCall->execute(Array， '/v1/payments/pa…'， 'POST'， '{"intent":"sale…"'， NULL) #2 C:'dev'htdocs'Shop'vendor'paypal'rest-api-sdk-php'lib' paypal' Api'Payment.php(422): paypal' Common'PayPalResourceModel::executeCall('/v1/payments/pa…'， 'POST'， '{"intent":"sale…"'， NULL, Object(PayPal'Rest'ApiContext)， NULL) #3 C:'dev'htdocs'Shop'app'controllers'CartController.php(183): PayPal'Api'Payment->create(Object(PayPal'Rest'ApiContext)) #4 [C中的内部函数:'dev'htdocs'Shop'vendor' PayPal'Rest - Api -sdk-php'lib'PayPal'Core'PayPalHttpConnection.php on line 180

你可以看一下$items array 条目数组美元

获得400异常意味着，paypal正在返回一些异常。获取有关该异常的更多细节。您需要捕获未捕获的异常PayPal'Exception'PayPalConnectionException以获得更多细节。

这个页面应该可以帮助你给出一些想法。下面是捕获该异常的示例代码:

try {
    $payment->create($apiContext);
} catch (PayPal'Exception'PayPalConnectionException $ex) {
    echo $ex->getCode(); // Prints the Error Code
    echo $ex->getData(); // Prints the detailed error message 
    die($ex);
} catch (Exception $ex) {
    die($ex);
}
