个人服务器搭建做网站

const http = require('http');
const fs = require('fs');
const path = require('path');

const server = http.createServer((req, res) => {
  const filePath = path.join(__dirname, 'public', req.url === '/' ? 'index.html' : req.url);
  const extname = path.extname(filePath);
  let contentType = 'text/html';

  switch (extname) {
    case '.js':
      contentType = 'text/javascript';
      break;
    case '.css':
      contentType = 'text/css';
      break;
    case '.json':
      contentType = 'application/json';
      break;
    case '.png':
      contentType = 'image/png';
      break;
    case '.jpg':
      contentType = 'image/jpg';
      break;
    case '.wav':
      contentType = 'audio/wav';
      break;
  }

  fs.readFile(filePath, (err, content) => {
    if (err) {
      if (err.code === 'ENOENT') {
        res.writeHead(404);
        res.end('File not found');
      } else {
        res.writeHead(500);
        res.end('Server error');
      }
    } else {
      res.writeHead(200, { 'Content-Type': contentType });
      res.end(content, 'utf-8');
    }
  });
});

server.listen(3000, () => {
  console.log('Server running at http://localhost:3000/');
});
