javascript - 如何摆脱 paypal-rest-sdk 的验证错误？

Question

我正在使用 paypal-rest-sdk 练习使用 paypal 结账。我设置了一个小测试，每当我在我的表单中单击提交时，我都会在 Chrome 中收到“localhost refused to connect”错误。我关闭了我的代理并清除了我的历史记录和缓存。我还仔细检查了我的客户端和来自 Paypal 的 key 。我不确定我做错了什么。这是我的代码:

应用程序.js:

const express = require('express');
const ejs = require('ejs');
const paypal = require('paypal-rest-sdk');

paypal.configure({
    'mode': 'sandbox', //sandbox or live
    'client_id': 'xxxxxxxx',
    'client_secret': 'xxxxxxx'
  });

const app = express();

app.set('view engine', 'ejs');

app.get('/', (req, res) => res.render('index'));

// create the json obj for the transaction with the order details
app.post('/pay', (req, res) => {
    const create_payment_json = {
        "intent": "sale",
        "payer": {
            "payment_method": "paypal"
        },
        "redirect_urls": {
            "return_url": "http://localhost:3000/success",
            "cancel_url": "http://localhost:3000/cancel"
        },
        "transactions": [{
            "item_list": {
                "items": [{
                    "name": "Red Sox Hat",
                    "sku": "001",
                    "price": "25.00",
                    "currency": "USD",
                    "quantity": 1
                }]
            },
            "amount": {
                "currency": "USD",
                "total": "1.00"
            },
            "description": "This is the payment description."
        }]
    };

    // pass in the object we've created and now create the actual payment
    paypal.payment.create(create_payment_json, function (error, payment) {
        if (error) {
            console.log(error);
            throw error;
        } else {
            console.log("Create Payment Response");
            console.log(payment);
            res.send('test');
        }
    });
});

app.listen(3000, () => console.log('Server Started'));

这是终端从错误中输出的内容:

  response:
   { name: 'VALIDATION_ERROR',
     details: [ [Object] ],
     message: 'Invalid request - see details',
     information_link: 'https://developer.paypal.com/docs/api/payments/#errors',
     debug_id: 'fb61fe9c14b46',
     httpStatusCode: 400 },
  httpStatusCode: 400 }

我希望在呈现付费路线时屏幕上出现“测试”消息，以便我知道连接有效，但到目前为止我得到的只是来自 Chrome 的“ERR_CONNECTION_REFUSED”。请让我知道我做错了什么。提前致谢。

您的付款 JSON 缺少必需的信息。请在下方查看有效的付款 JSON:

{
"intent": "sale",
"payer": {
    "payment_method": "paypal"
},
"redirect_urls": {
    "return_url": "http://www.example.com/return_url",
    "cancel_url": "http://www.example.com.br/cancel"
},
"transactions": [
    {
        "amount": {
            "currency": "USD",
            "total": "200.00",
            "details": {
                "shipping": "10.00",
                "subtotal": "190.00"
            }
        },
        "item_list": {
            "items": [
                {
                    "name": "Foto 1",
                    "currency": "USD",
                    "sku": "123",
                    "quantity": "1",
                    "price": "190.00"
                }
            ]
        },
