如何在不遇到CORS的情况下从GitHub页面发送请求？

<script>
function handleResponse(response) {
    console.log(response);
}
</script>
<script src="https://example.com/api/data?callback=handleResponse"></script>

const express = require('express');
const request = require('request');

const app = express();

app.use('/proxy', (req, res) => {
    const url = 'https://example.com/api/data' + req.url;
    req.pipe(request(url)).pipe(res);
});

app.listen(3000, () => {
    console.log('Proxy server running on port 3000');
});

fetch('http://localhost:3000/proxy')
    .then(response => response.json())
    .then(data => console.log(data));

fetch('https://cors-anywhere.herokuapp.com/https://example.com/api/data')
    .then(response => response.json())
    .then(data => console.log(data));

const express = require('express');
const app = express();

app.use((req, res, next) => {
    res.header('Access-Control-Allow-Origin', '*');
    res.header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE');
    res.header('Access-Control-Allow-Headers', 'Content-Type');
    next();
});

app.get('/data', (req, res) => {
    res.json({ message: 'This is data from the server' });
});

app.listen(3000, () => {
    console.log('Server running on port 3000');
});
