Paypal: PHP SDK错误传入的JSON请求没有映射到API请求

Question

我用的是PHP Paypal SDK:https://github.com/paypal/PayPal-PHP-SDK

通过PHP SDK引用PayPal REST API返回“传入JSON请求未映射到API请求”

继续https://stackoverflow.com/questions/39827032/paypal-how-to-get-payment-id-on-basis-of-transaction-id

根据已经可用的交易Id，需要获得付款Id

我已经尝试了下面的代码

require __DIR__ . '/bootstrap.php';

use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\CreditCard;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\FundingInstrument;
use PayPal\Api\Transaction;
// Extra Code
use PayPal\Api\PaymentDetail;

$payer = new Payer();
$payer->setPaymentMethod('paypal');

$transaction = new PaymentDetail(
        '{
          "method" : "CASH",
          "date" : "2014-07-06 03:30:00 PST",
          "note" : "Cash received."
        }'
);

$transaction->setTransactionId("3NT32794KF4824703");

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

// For Sample Purposes Only.
$request = clone $payment;

try {
    $payment->create($apiContext);
} catch (\PayPal\Exception\PayPalConnectionException $ex) {
    echo $ex->getData();
}

echo "<pre>";
print_r($payment);
exit;

当我运行上面的代码时，它给出了下面的错误

{"name":"MALFORMED_REQUEST","message":"Incoming JSON request does not map to API request","information_link":"https://developer.paypal.com/webapps/developer/docs/api/#MALFORMED_REQUEST","debug_id":"aa8bfa2a41f1f"}

                                (
                                    [method] => CASH
                                    [date] => 2014-07-06 03:30:00 PST
                                    [note] => Cash received.
                                    [transaction_id] => 3NT32794KF4824703
                                )

                        )

                )

        )

)

如何解决上述错误？请指导

PayPal技术支持的回应

经过与开发团队的讨论和测试，他们确认您不能使用TransactionId来检索PaymentId。PaymentId是在初始REST API调用时生成的。这仅发生在REST API上。

交易 ID 可以在 REST API 执行付款、经典 API [NVP/SOAP] DoEC API 或正常按钮付款完成后生成。反向搜索以查找付款ID将永远无法工作。

至于现在，您唯一的解决方法是记录每个REST API请求，无论它是否失败以跟踪PaymentId。

需要实现：一旦付款完成，它将被搁置。X天后，它将被处理。处理后，金额将从客户的账户中扣除。

Answer 1

首先，您使用进行付款创建请求

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

>

在创建响应中，您将获得“apporval url”，该批准url用于用户在那里付款。

然后，您将通过“$redirectUrls”中发送的url接收来自paypal的通知。

在这里，您将获得“付款ID”和“付款人ID”，使用该ID执行付款。

$execution = new PaymentExecution();
$execution->setPayerId($da['PayerID']);
$apiContext=$this->apicontext();
$res = $payment->execute($execution, $apiContext);
