Node.js搭建静态服务器

let http = require('http'); let url = require('url'); let fs = require('fs'); let path = require('path'); http.createServer((req, res) => { if (req.url === '/favicon.ico') return; var pathname = url.parse(req.url).pathname; //默认首页 if (pathname === '/') { pathname = 'index.html'; } //拓展名 var extname = path.extname(pathname); //真的读取这个文件 fs.readFile('./static/' pathname, (err, data) => { if (err) { console.log(err); //如果此文件不存在，就应该返回404 fs.readFile('./static/404.html', (err, data) => { res.writeHead(200, {'content-type':'text/html;charset=utf-8'}); res.end(data); return; }) return; } //MIME类型，就是 //网页文件：text/html; //png: image/png var mime = getMime(extname); res.writeHead(200, {"Content-Type": mime}); res.end(data); }); // res.end(pathname ' ' extname); }).listen(3000); function getMime(extname) { //表驱动法 var extObj = { ".html": "text/html", ".png": "image/png", ".jpg": "image/jpeg", ".css": "text/css", ".js": "text/javascript" }; return extObj[extname]; }
