我正在尝试在Node.Js环境中执行PayPal 支付，但我似乎无法理解它。付款没有完成。
我认为我没有正确设置参数，或者我的代码可能需要重新组织。
请帮我把头绕过去，并最终开始朝着正确的方向前进？
谢谢大家。
本地客户端浏览器：
<script>
paypal.Button.render({
env: 'sandbox', // Or 'production'
// Set up the payment:
// 1. Add a payment callback
payment: function(data, actions) {
// 2. Make a request to your server
return actions.request.post('/my-api/create-payment/')
.then(function(res) {
// 3. Return res.id from the response
return res.id;
});
},
// Execute the payment:
// 1. Add an onAuthorize callback
onAuthorize: function(data, actions) {
// 2. Make a request to your server
return actions.request.post('/my-api/execute-payment/', {
paymentID: data.paymentID,
payerID: data.payerID
})
.then(function(res) {
// 3. Show the buyer a confirmation message.
});
}
}, '#paypal-button');
</script>
