先实现在url中输入文件路径能展示对应文件内容功能

const http = require(‘http‘)const fs = require(‘fs‘)const server = http.createServer()const wwwDir = ‘/Users/lianglanlan/Desktop/code/study/node/www‘server.on(‘request‘, (req, res) => { const url = req.url let filePath = ‘/index.html‘ if (url !== ‘/‘) { filePath = url } fs.readFile(wwwDir + filePath, (err, data) => { if (err) { console.log(err) return res.end(‘404 Not Found‘) } res.end(data) })})server.listen(3010, () => { console.log(‘running...‘)})
