【问题描述】：

我正在尝试为智能按钮贝宝实现服务器端集成。我已经尝试解决这个问题好几天了。我是新手，这是一个个人项目，我正在努力学习。

每次单击贝宝按钮时，我都会不断收到“错误：需要传递订单 ID”。我错过了什么？

这是我的客户端代码：

paypal.Buttons(
// Customize button (optional)
style: 
    color: 'blue',
    shape: 'pill',
,
//Set up a payment
// This function sets up the details of the transaction, including the amount and line item details.
createOrder: function()
    return fetch('<?php echo URLROOT; ?>/libraries/Paypal.php', 
        method: 'post',
        headers: 
        'content-type': 'application/json',
        ,
    ).then(function(res)
        //console.log(res.json());
        return res.text();
    ).then(function(data)
        return data.orderID; // Use the same key name for order ID on the client and server
    );
,
// Execute the payment
onApprove: function (data) 
    //This function captures the funds from the transaction.
    return fetch('<?php echo URLROOT; ?>/libraries/Paypal.php', 
        method: 'post',
        headers: 
            'content-type': 'application/json'
        ,
        body: JSON.stringify(
            orderID: data.orderID
        )

    ).then(function (res) 
        return res.json();
    ).then(function(orderData)
        if (errorDetail && errorDetail.issue === 'INSTRUMENT_DECLINED') 
          return actions.restart();
        
        if (errorDetail) 
            var msg = 'Sorry, your transaction could not be processed.';
            if (errorDetail.description) msg += '\n\n' + errorDetail.description;
            if (orderData.debug_id) msg += ' (' + orderData.debug_id + ')';
            return alert(msg);
        
      alert('Transaction completed by ' + orderData.payer.name.given_name);
  );
,
onError: function (err)
    alert('An Error occured ' + err);

      
).render('#payment-btn');

这是我的服务器端：

// Creating an environment
$clientId = "HIDDEN";
$clientSecret = "HIDDEN";
$environment = new SandboxEnvironment($clientId, $clientSecret);
$client = new PayPalHttpClient($environment);
// Construct a request object and set desired parameters
// Here, OrdersCreateRequest() creates a POST request to /v2/checkout/orders
use PayPalCheckoutSdk\Orders\OrdersCreateRequest;
$request = new OrdersCreateRequest();
$request->prefer('return=representation');
$request->body = array(
    'intent' => 'CAPTURE',
    'application_context' =>
        array(
            'locale' => 'en-US',
            'return_url' => URLROOT.'/bookings/payment',
            'cancel_url' => URLROOT.'/bookings/payment'
        ),
    'purchase_units' =>
        array(
            0 =>
                array(
                    'amount' =>
                        array(
                            'currency_code' => 'EUR',
                            'value' => $_SESSION["total-price"]
                        )
                )
        )
);
try 
    // Call API with your client and get a response for your call
    $response = $client->execute($request);

    return $response->result;

    // If call returns body in response, you can get the deserialized version from the result attribute of the response
    print_r($response);
catch (HttpException $ex) 
    echo $ex->statusCode;
    print_r($ex->getMessage());

use PayPalCheckoutSdk\Orders\OrdersCaptureRequest;
// Here, OrdersCaptureRequest() creates a POST request to /v2/checkout/orders
// $response->result->id gives the orderId of the order created above
//$orderId = $response->result->id;
$request = new OrdersCaptureRequest($orderId);
$request->prefer('return=representation');
try 
    // Call API with your client and get a response for your call
    $response = $client->execute($request);

    // If call returns body in response, you can get the deserialized version from the result attribute of the response
    print_r($response);
catch (HttpException $ex) 
    echo $ex->statusCode;
    print_r($ex->getMessage());

【参考方案1】：

你从你的服务器返回给客户端的究竟是什么？您是否在服务器端或更简单地使用浏览器开发工具的“网络”选项卡记录了此内容？

在您的客户端代码中，您有：

return data.orderID; // Use the same key name for order ID on the client and server

具体来说，您在哪里将键“orderID”设置为 PayPal API 返回的“id”值？我没有看到这种情况发生在任何地方。

如果您的服务器只是反刍 PayPal API JSON，请将您的客户端代码更改为 return data.id，因为 id 密钥是 PayPal v2/checkout/orders API 使用的。

以下是基于 html/JS 的最直接示例：https://developer.paypal.com/demo/checkout/#/pattern/server

我为此花费了太多时间，这非常容易。顺便说一句，我不知道“网络”工具，这也有很大帮助。谢谢，非常感谢。
