【问题描述】：

我在使用 PayPal REST API 时出错，但我无法在任何地方找到解决方案。我正在尝试将用户发送到 PayPal 以支付会话数组中的指定项目。我已尝试更改付款方式、意图和 URL。

    $this->setupCurl();
    $this->setupPayPal();

    $this->payer = new Payer();
    $this->details = array();
    $this->amount = array();
    $this->transaction = array();
    $this->redirectUrls = new RedirectUrls();
    $this->payment = new Payment();

    $this->payer->setPaymentMethod('paypal'); // TODO paypal . credit_card

    foreach ($cart as $id => $item) 
        $this->details[$id] = new Details();
        $this->amount[$id] = new Amount();
        $this->transaction[$id] = new Transaction();

        $this->details[$id]->setShipping('0.00')
                      ->setTax('0.00')
                      ->setSubtotal(formatMoney($this->products[$id]['price'] * $item['quantity'], '', 2)); // TODO

        $this->amount[$id]->setCurrency('AUD')
                     ->setTotal(formatMoney($this->products[$id]['price'] * $item['quantity'], '', 2))
                     ->setDetails($this->details[$id]);

        $this->transaction[$id]->setAmount($this->amount[$id])
                          ->setDescription($this->products[$id]['name']); // TODO
    

    $this->redirectUrls->setReturnUrl('https://warsentech.com/pay?approved=true')
                       ->setCancelUrl('https://warsentech.com/pay?approved=false');

    $this->payment->setIntent('authorize') // TODO sale . buy
                  ->setPayer($this->payer)
                  ->setRedirectUrls($this->redirectUrls)
                  ->setTransactions($this->transaction); // TODO - add transactions into array from the cart items

    try 
        $this->payment->create($this->paypal);

        $hash = md5($this->payment->getId());
        $_SESSION['paypal_hash'] = $hash;
        if ($this->databaseConnection()) 
            $result = $this->db_connection->prepare('INSERT INTO transactions_paypal (user_id, payment_id, hash, complete) VALUES (:user_id, :payment_id, :hash, 0)');
            $result->execute([
                'user_id' => $_SESSION['user_id'],
                'payment_id' => $this->payment->getId(),
                'hash' => $hash
            ]);
        
     catch (Exception $e) 
        die(paypalError($e));
    

    foreach ($this->payment->getLinks() as $link) 
        if ($link->getRel() == 'approval_url') 
            $redirectUrl = $link->getHref();
        
    

完整的错误信息：

【参考方案1】：

我会推荐两件事来解决这个问题：

从您看到的错误消息中，您看到的错误属于PayPal\Exception\PayPalConnectionException 类型。我们有一个特殊的方法getData() 来检索有关错误的确切详细信息。

你可以这样做：

try 
    $this->payment->create($this->paypal);

    $hash = md5($this->payment->getId());
    $_SESSION['paypal_hash'] = $hash;
    if ($this->databaseConnection()) 
        $result = $this->db_connection->prepare('INSERT INTO transactions_paypal (user_id, payment_id, hash, complete) VALUES (:user_id, :payment_id, :hash, 0)');
        $result->execute([
            'user_id' => $_SESSION['user_id'],
            'payment_id' => $this->payment->getId(),
            'hash' => $hash
        ]);
    
 catch (PayPal\Exception\PayPalConnectionException $e) 
    echo $e->getData(); // This will print a JSON which has specific details about the error.
    die(paypalError($e));

如果您希望在集成我们的 SDK 时获得帮助，有很多文档可以帮助您。以下是您应该关注的最有趣的一个：

演示每个 API 操作的示例：http://paypal.github.io/PayPal-PHP-SDK/sample/ 如何通过一个命令在本地机器上运行这些示例：https://github.com/paypal/PayPal-PHP-SDK/wiki/Samples 解释如何开始使用我们的 API 的 Wiki 页面：https://github.com/paypal/PayPal-PHP-SDK/wiki

具体来说，您应该查看这个示例，该示例准确地展示了您正在尝试做的事情：http://paypal.github.io/PayPal-PHP-SDK/sample/doc/payments/CreatePaymentUsingPayPal.html
