Node.js 自带的 http 模块来实现一个简单的本地服务器

1.创建一个 server.js 文件：

const http = require('http');
const fs = require('fs');
const path = require('path');const server = http.createServer((req, res) => {// 获取请求的文件路径const filePath = path.join(__dirname, 'dist', req.url);// 读取文件内容并返回给客户端fs.readFile(filePath, (err, data) => {if (err) {res.writeHead(404, { 'Content-Type': 'text/plain' });res.end('Not Found');} else {res.writeHead(200, { 'Content-Type': 'text/html' });res.end(data);}});
});const port = 3000;
server.listen(port, () => {console.log(`Server is running at http://127.0.0.1:${port}`);
});
