如何将订单 ID 传递给 Paypal Button?

How to pass order ID to Paypal Button?

我通过我的 php sdk 创建订单。

像这样

$result = json_decode((string) $response->getBody());

echo $result->id; // id of the created order

现在我有了这个订单号。但是...如何将订单 ID 传递给 Paypal Button? 像这样

`paypal.Buttons({

    // Set up the transaction
    createOrder: function(data, actions) { //I don't need create order,I have created an order
        return actions.order.create({
            purchase_units: [{
                amount: {
                    value: '88.44'
                }
            }]
        });
    },

    // Finalize the transaction
    onApprove: function(data, actions) {
        return actions.order.capture().then(function(orderData) {
            // Successful capture! For demo purposes:
            console.log('Capture result', orderData, JSON.stringify(orderData, null, 2));
            var transaction = orderData.purchase_units[0].payments.captures[0];
            alert('Transaction '+ transaction.status + ': ' + transaction.id + '\n\nSee console for all available details');

            // Replace the above to show a success message within this page, e.g.
            // const element = document.getElementById('paypal-button-container');
            // element.innerHTML = '';
            // element.innerHTML = '<h3>Thank you for your payment!</h3>';
            // Or go to another URL:  actions.redirect('thank_you.html');
        });
    }


}).render('#paypal-button-container');

在您的服务器上创建两个路由,一个用于创建订单(和 return 结果 JSON),另一个将订单 ID 作为参数并捕获它(和 return是 JSON 结果)。

这两条路线都应该 return/output 只有 JSON(没有 HTML 或文本)。

将这两条路线与此批准流程配对:https://developer.paypal.com/demo/checkout/#/pattern/server
