使用React, Node, Express解决未经授权的API调用

Question

我正在尝试使用Marea Tide Api来构建一个基于位置(纬度，经度)返回结果的潮汐应用程序。

由于CORS错误，我最初很难从前端成功获取。我现在正试图建立一个快速后端来隐藏我的api密钥和导航的代理CORS问题。

当我试图导航到localhost:8000/tides时，我一直得到一个未经授权的错误。

表达:

const PORT = 8000;
const express = require('express');
const cors = require('cors');
const axios = require('axios');
const { application, json } = require('express');
require('dotenv').config

const backend = express()
backend.listen(PORT, () => console.log(`Tide backend is working on PORT:${PORT}`))
backend.get('/tides', (req, res, next) => {
const url = 'https://api.marea.ooo/v2/tides';
const options = {
params: {
duration: 1440,
interval: 60,
latitude: 36.888,
longitude: -76.100,
}
};
const config = {
headers: {
'x-marea-api-token': process.env.MareaToken,
}
};

axios.get(url, options, config)
.then(response => {console.log(response)})
.catch(err => console.log(err))
});

终端错误:

axios.get()只接受两个参数…

axios。get (url(配置)

结合你的options和config对象，不要忘记发送一个实际的响应。

axios.get(url, { ...options, ...config })
.then(({ data }) => res.json(data))
.catch(next);
