问题描述
我正在尝试调用CoinMarketCap的公共API,但是它总是失败,并出现以下错误:
I am trying to call CoinMarketCap's public API but it always fails with following error:
error occured Error: getaddrinfo ENOTFOUND api.coinmarketcap.com api.coinmarketcap.com:443
当我从浏览器中调用URL时,它会立即返回结果.代码很简单:
When I call the URL from the browser it returns the result instantly. The code is pretty simple:
const functions = require('firebase-functions');
const axios = require('axios');
exports.getBtcPrice = functions.https.onRequest((req, res) => {
axios.get('https://api.coinmarketcap.com/v1/ticker/bitcoin')
.then( (response) => {
console.log(response);
res.send("data received");
})
.catch((error) => {
console.log(error);
res.send("error occured "+ error)
});
});
推荐答案
如果您是免费计划,则具有firebase功能的出站网络仅适用于google服务.他们提到这是定价页面 https://firebase.google.com/pricing/
If you are on the free plan outbound networking with firebase functions only works with google services. They mention this is the cloud function section on the pricing page https://firebase.google.com/pricing/
如果要使用第三方API,则必须转到付费层.
You have to move to a paid tier if you want to use third-party APIs.
