使用存储在库PHP中的信用卡进行的PayPal付款

Question

我有一个信用卡详细信息的ID，该ID已保存在Paypal库CARD-xxxxxxxxxxxxxxxxxx中。我需要使用php-paypal-SDK用这张卡付款。为此，我编写了波纹管代码。

<?php
require 'PayPal-PHP-SDK-master/vendor/autoload.php';

$clientId       = 'xxxxxxxxxxxxxxxxxx';
$clientSecret   = 'xxxxxxxxxxxxxxxxxx';

use PayPal\Auth\OAuthTokenCredential;
use PayPal\Rest\ApiContext;
use PayPal\Exception\PayPalConnectionException;
use PayPal\Api\Payment;
use PayPal\Api\Payer;
use PayPal\Api\FundingInstrument;
use PayPal\Api\CreditCard;
use PayPal\Api\CreditCardToken;
use PayPal\Api\Transaction;


$sdkConfig = array(
    "mode" => "sandbox"
);

$apiContext =  $apiContext = new ApiContext(new OAuthTokenCredential(
    $clientId,
    $clientSecret
));

$credit_card_token = new CreditCardToken();
$credit_card_token->setCreditCardId('CARD-xxxxxxxxxxxxxxxxxx');

$fundinginstrument = new FundingInstrument();
$fundinginstrument->setCreditCardToken($credit_card_token);


$payer     = new Payer();
$payer->setPaymentMethod('credit_card');
$payer->setFundingInstruments(array($fundinginstrument));

$payment    = new Payment();

$payment->setIntent('sale');

$payment->setPayer($payer);

$transaction = new Transaction();
$transaction->setAmount('10.00');
$transaction->setDescription('Test payment');
$payment->setTransactions(array($transaction));

$request = clone $payment;

try {
    $output = $payment->create($apiContext);
    print_r($output);

} catch (PayPal\Exception\PayPalConnectionException $pce) {

    echo '<pre>';print_r(json_decode($pce->getData()));exit;
    exit(1);
}

但是它会引发如下错误

MALFORMED_REQUEST-传入的JSON请求未映射到API请求

此代码出了什么问题？这是我第一次使用此SDK。

Answer 1

您的代码看起来不错，我认为这是与货币相关的问题。添加\PayPal\Api\Amount，然后设置交易金额。按照下面的代码

$amount = new \PayPal\Api\Amount();
$amount->setCurrency('USD');
$amount->setTotal('10.00');

$transaction = new \PayPal\Api\Transaction();
$transaction->setAmount($amount);

这里是完整代码

<?php

require 'vendor/autoload.php';

$clientId     = 'CLIENT_ID';
$clientSecret = 'CLIENT_SECRET';

use PayPal\Api\Amount;
use PayPal\Api\CreditCardToken;
use PayPal\Api\FundingInstrument;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\Transaction;
use PayPal\Auth\OAuthTokenCredential;
use PayPal\Exception\PayPalConnectionException;
use PayPal\Rest\ApiContext;

$sdkConfig = array(
    "mode" => "sandbox",
);

$apiContext = $apiContext = new ApiContext(new OAuthTokenCredential(
    $clientId,
    $clientSecret
));

$creditCardToken = new CreditCardToken();
$creditCardToken->setCreditCardId("CREDIT_CARD_ID");
$fi = new FundingInstrument();
$fi->setCreditCardToken($creditCardToken);
$payer = new Payer();
$payer->setPaymentMethod("credit_card");
$payer->setFundingInstruments(array($fi));

$payment = new Payment();

$payment->setIntent('sale');

$payment->setPayer($payer);

$amount = new Amount();
$amount->setCurrency('USD');
$amount->setTotal('1.00');

$transaction = new Transaction();
$transaction->setAmount($amount);
$payment->setTransactions(array($transaction));

// $request = clone $payment;

try {
    $output = $payment->create($apiContext);
    echo "<pre>";
    print_r($output);

} catch (PayPal\Exception\PayPalConnectionException $pce) {

    echo '<pre>';
    print_r(json_decode($pce->getData()));exit;
    exit(1);
}

如果仍然无法使用，则可以使用curl或任何HTTP客户端。为了演示，我使用了GuzzleHttp

$uri      = 'https://api.sandbox.paypal.com/v1/oauth2/token';
$clientId = 'CLIENT_ID';
$secret   = 'CLIENT_SECRET';

$client   = new \GuzzleHttp\Client();
$response = $client->request('POST', $uri, [
    'headers' =>
    [
        'Accept'          => 'application/json',
        'Accept-Language' => 'en_US',
        'Content-Type'    => 'application/x-www-form-urlencoded',
    ],
    'body'    => 'grant_type=client_credentials',

    'auth'    => [$clientId, $secret, 'basic'],
]
);

$data = json_decode($response->getBody(), true);

$access_token = $data['access_token'];

$payment_uri = 'https://api.sandbox.paypal.com/v1/payments/payment';
$data        = '{
  "intent": "sale",
  "payer": {
    "payment_method": "credit_card",
    "funding_instruments": [
    {
      "credit_card_token": {
        "credit_card_id": "CREDIT_CARD_ID"
      }
    }]
  },
  "transactions": [
  {
    "amount": {
      "total": "6.70",
      "currency": "USD"
    },
    "description": "Payment by vaulted credit card."
  }]
}';
$payment = $client->request('POST', $payment_uri, [
    'headers' =>
    [
        'Content-Type'  => 'application/json',
        'Authorization' => 'Bearer ' . $access_token,
    ],
    'body'    => $data,
]
);

$transaction = json_decode($payment->getBody(), true);

echo "<pre>";

print_r($transaction);
