要在PHP中使用PayPal支付接口,您需要遵循以下步骤:

  1. 创建PayPal商家账户:首先,您需要注册一个PayPal商家账户。访问https://www.paypal.com/,然后点击“商家工具”并注册。

  2. 获取API凭据:登录到您的PayPal商家账户,然后转到“我的业务设置”>“API安全”>“API凭据”。在这里,您将看到您的API用户名、密码和签名。复制这些值,因为您将在PHP代码中使用它们。

  3. 下载PayPal PHP SDK:访问https://github.com/paypal/PayPal-PHP-SDK,然后下载或克隆存储库。将其解压缩到您的项目文件夹中。

  4. 配置autoload.php:在您的PHP文件中,包含PayPal SDK的autoload.php文件。例如:

require 'path/to/PayPal-PHP-SDK/autoload.php';
  1. 配置PayPal API上下文:使用您在步骤2中获得的API凭据创建一个PayPal API上下文。例如:
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;

$api_username = "your_api_username";
$api_password = "your_api_password";
$api_signature = "your_api_signature";

$credentials = new OAuthTokenCredential($api_username, $api_password, $api_signature);
$apiContext = new ApiContext($credentials);
  1. 创建支付:现在您可以使用PayPal API创建支付。例如:
use PayPal\Api\Payer;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Details;
use PayPal\Api\Amount;
use PayPal\Api\Transaction;
use PayPal\Api\RedirectUrls;
use PayPal\Api\Payment;

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

$item1 = new Item();
$item1->setName('Item 1')
    ->setCurrency('USD')
    ->setQuantity(1)
    ->setPrice(7.5);

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

$details = new Details();
$details->setShipping(1.2)
    ->setTax(1.3)
    ->setSubtotal(7.50);

$amount = new Amount();
$amount->setCurrency("USD")
    ->setTotal(10)
    ->setDetails($details);

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

$redirectUrls = new RedirectUrls();
$redirectUrls->setReturnUrl("http://yourdomain.com/return")
    ->setCancelUrl("http://yourdomain.com/cancel");

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

try {
    $payment->create($apiContext);
} catch (Exception $ex) {
    echo $ex;
    exit(1);
}

$approvalUrl = $payment->getApprovalLink();
header("Location: " . $approvalUrl);
  1. 处理返回和取消URL:在您的返回和取消URL中,您需要处理支付确认和取消。例如:
// return.php
$paymentId = $_GET['paymentId'];
$payment = Payment::get($paymentId, $apiContext);
$execution = new PaymentExecution();
$execution->setPayerId($_GET['PayerID']);

try {
    $result = $payment->execute($execution, $apiContext);
    // Payment is successful, update your database and display a success message
} catch (Exception $ex) {
    // Payment failed, display an error message
}

// cancel.php
// Display a cancellation message

现在,您已经成功地在PHP中设置了PayPal支付接口。用户可以通过PayPal进行支付,您可以处理支付确认和取消。
