我正在尝试使用 URL https://www.coindesk.com/api/ 来使用比特币价格历史记录其余 Web 服务 ( https://api.coindesk.com/v1/bpi/historical/close.json ) .

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，下面的代码不起作用，当我使用 Postman 向 m Node/Express 服务器发送 GET 请求时，我在这篇文章的底部得到了 HTML 结果，看起来像验证码:

Node/表达代码:

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 发出 GET 请求后的响应:

最佳答案

我认为你可以使用 jQuery ajax 调用获取信息，然后将其发送到你的 Express 服务器并处理它

$.ajax({
  url: "https://api.coindesk.com/v1/bpi/historical/close.json",
})
.done(function( data ) {
    alert(data)
  });
});
