【问题描述】：
我正在尝试使用 URL https://api.coindesk.com/v1/bpi/historical/close.json 使用比特币价格历史记录休息网络服务 (https://www.coindesk.com/api/)。
当我在浏览器中输入以前的 URL 时它工作正常，但是当我使用 Node/Express 获取数据然后重新发送它时，使用下面的代码它不起作用，当我向 m 发送 GET 请求时带有 Postman 的 Node/Express 服务器 我在这篇文章的底部得到了 HTML 结果，它看起来像一个验证码：
节点/Express 代码：
const express = require('express');
const request = require('request');
const router = express.Router();
router.get('/bitcoinPrices', function(req, res) {
request('https://api.coindesk.com/v1/bpi/historical/close.json', function (error, response, body) {
console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
console.log('body:', body); // Print the HTML for the Google homepage.
res.send(body);
});
});
module.exports = router;对http://localhost:3000/api/bitcoinPrices 的 GET 请求后的响应：

那是因为他们使用 CloudFlare 但没有正确设置它以使用 API。没有稳定和合法的方法可以绕过它。您应该联系他们的支持。
