PayPal-PHP-SDK不能使用列表中的单个项目

Question

我正在关注this example并在Laravel应用程序中使用它。在测试过程中我注意到，当我通过只有单个项目的数组 $itemList->setItems($items);我得到以下错误：Got Http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment

这里的代码块我使用：

$card = new CreditCard(); 
    $card->setType("visa") 
     ->setNumber("4669424246660779") 
     ->setExpireMonth("11") 
     ->setExpireYear("2019") 
     ->setCvv2("012") 
     ->setFirstName("Joe") 
     ->setLastName("Shopper"); 
    $fi = new FundingInstrument(); 
    $fi->setCreditCard($card); 
    $payer = new Payer(); 
    $payer->setPaymentMethod("credit_card") 
     ->setFundingInstruments(array($fi)); 
    $items[0] = new Item(); 
    $items[0]->setName('Ground Coffee 40 oz') 
     ->setDescription('Ground Coffee 40 oz') 
     ->setCurrency('USD') 
     ->setQuantity(1) 
     ->setTax(0.3) 
     ->setPrice(7.50); 
    /* 
    Removing this comment makes this code work 
    $items[1] = new Item(); 
    $items[1]->setName('Granola bars') 
     ->setDescription('Granola Bars with Peanuts') 
     ->setCurrency('USD') 
     ->setQuantity(5) 
     ->setTax(0.2) 
     ->setPrice(2); */ 

    $itemList = new ItemList(); 
    $itemList->setItems($items); 
    $details = new Details(); 
    $details->setShipping(1.2) 
     ->setTax(1.3) 
     ->setSubtotal(17.5); 
    $amount = new Amount(); 
    $amount->setCurrency("USD") 
     ->setTotal(20) 
     ->setDetails($details); 
    $transaction = new Transaction(); 
    $transaction->setAmount($amount) 
     ->setItemList($itemList) 
     ->setDescription("Payment description") 
     ->setInvoiceNumber(uniqid()); 
    $payment = new Payment(); 
    $payment->setIntent("sale") 
     ->setPayer($payer) 
     ->setTransactions(array($transaction)); 
    $request = clone $payment; 
    try { 
     $payment->create($apiContext); 
    } catch (Exception $ex) { 
     ResultPrinter::printError('Create Payment Using Credit Card. If 500 Exception, try creating a new Credit Card using <a href="https://ppmts.custhelp.com/app/answers/detail/a_id/750">Step 4, on this link</a>, and using it.', 'Payment', null, $request, $ex); 
     exit(1); 
    } 
    //ResultPrinter::printResult('Create Payment Using Credit Card', 'Payment', $payment->getId(), $request, $payment); 

    return $payment; 

在哪里，如果我取消$items[1]部分的注释，它工作正常。为什么会发生？

它抛出400异常，因为总数不匹配。您可以捕捉适当的异常与适当的消息如下所示： https://github.com/paypal/PayPal-PHP-SDK/wiki/exception-%27PayPal%5CException%5CPayPalConnectionException%27-with-message-%27Got-Http-response-code-400-when-accessing

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); 
} 

在你的情况，因为你删除了第二个项目，总不匹配。用适当的值替换下面的代码，它应该工作。

$details->setShipping(1.2) 
     ->setTax(1.3) 
     ->setSubtotal(7.8); 
    $amount = new Amount(); 
    $amount->setCurrency("USD") 
     ->setTotal(10.3)
