底下的範例在啟動之後自動指定同一資料夾為 HTTP Server 之根目錄:
var http = require('http'), url = require('url'), path = require('path'), fs = require('fs'); var mimeTypes = { "html": "text/html", "jpeg": "image/jpeg", "jpg": "image/jpeg", "png": "image/png", "js": "text/javascript", "css": "text/css"}; http.createServer(function(req, res) { var uri = url.parse(req.url).pathname; console.log(uri); var empty =function(){ res.writeHead(200, {'Content-Type': 'text/plain'}); res.end(); }; if (uri ==='/'){ return empty(); }; var filename = path.join(process.cwd(), uri); fs.exists(filename, function(exists){ if(!exists || fs.lstatSync(filename).isDirectory()===true){ return empty(); } res.writeHead(200, { 'Content-Type':mimeTypes[path.extname(filename).split(".")[1]] }); fs.createReadStream(filename).pipe(res); }); //end fs.exists }).listen(8080);在同一資料夾裡擺一個檔案 (index.html),啟動之後利用網址 http://localhost:8080/index.html 即可瀏覽該檔案。
