【问题描述】：

我正在尝试让“使用 PayPal 帐户付款”与 PHP 一起使用，但我不断收到响应“传入的 JSON 请求未映射到 API 请求”。我已经检查了我使用 jsonlint 发送的 JSON，它是有效的 JSON。它似乎也与此付款类型的示例中发送的内容相匹配。

require __DIR__ . '/../bootstrap.php';
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;
session_start();

// ### Payer
$payer = new Payer();
$payer->setPaymentMethod("paypal");

// ### Itemized information
$item1 = new Item();
$item1->setName($item1Name)
    ->setCurrency($currency)
    ->setQuantity($item1Quantity)
    ->setPrice($item1Price);
$item2 = new Item();
$item2->setName($item2Name)
    ->setCurrency($currency)
    ->setQuantity($item2Quantity)
    ->setPrice($item2Price);

$itemList = new ItemList();
$itemList->setItems(array($item1, $item2));

// ### Additional payment details
$details = new Details();
$details->setShipping($shipping)
    ->setTax($tax)
    ->setSubtotal($subtotal);

// ### Amount
$amount = new Amount();
$amount->setCurrency($currency)
    ->setTotal(number_format(($subtotal + ($shipping + $tax)), 2))
    ->setDetails($subtotal);

// ### Transaction
$transaction = new Transaction();
$transaction->setAmount($amount)
    ->setItemList($itemList)
    ->setDescription("Payment description");

// ### Redirect urls
$baseUrl = getBaseUrl();
$redirectUrls = new RedirectUrls();
$redirectUrls->setReturnUrl("$baseUrl/ExecutePayment.php?success=true")
    ->setCancelUrl("$baseUrl/ExecutePayment.php?success=false");

// ### Payment
$payment = new Payment();
$payment->setIntent("sale")
    ->setPayer($payer)
    ->setRedirectUrls($redirectUrls)
    ->setTransactions(array($transaction));

// ### Create Payment
$payment->create($apiContext);
} catch (PayPal\Exception\PPConnectionException $ex) {
    echo "Exception: " . $ex->getMessage() . PHP_EOL;
    var_dump($ex->getData());   
    exit(1);
}

// ### Get redirect url
foreach($payment->getLinks() as $link) {
    if($link->getRel() == 'approval_url') {
        $redirectUrl = $link->getHref();
        break;
    }
}

// ### Redirect buyer to PayPal website
$_SESSION['paymentId'] = $payment->getId();
if(isset($redirectUrl)) {
    header("Location: $redirectUrl");
    exit;
}

PayPal.log 包含以下内容：

非常感谢任何帮助。

提前致谢。

【问题讨论】：

我已经想通了。我将一个数字传递给 Amount->SetDetails 而不是所需的对象。 // ### 金额 $amount = new Amount(); $amount->setCurrency($currency) ->setTotal(number_format(($subtotal + ($shipping + $tax)), 2)) ->setDetails($subtotal);帮助我弄清楚的一件事是将 PayPal 示例 (/sample/PayPal.log) 的日志与我自己尝试的日志进行比较。避免了灾难！
