代碼如下，開啟服務器后，瀏覽器輸入地址+端口號調用fs時瀏覽器會顯示無法訪問。其他url正常。var http = require('http');var fs = require('fs');http.createServer(function (req, res) {res.writeHead(200, { 'Content-Type': 'text/plain;charset=utf-8' });res.write("Hello NodeJs");console.log(req.url);if (req.url === '/') {res.writeHead(200, { 'Content-Type': 'text/html' })fs.readFileSync('./webroot/zhuyemian.html', 'utf-8', function (err, data) {if (err) {throw err;}console.log(data);res.end();});res.end();} else if (req.url === '/login') {res.write("歡迎來到登錄頁面");res.end();} else if (req.url === '/register') {res.write("歡迎來到注冊頁面");res.end();} else if (req.url === '/admin') {res.write("歡迎來到后臺管理頁面");res.end();} else {res.write("404 你找的頁面飛了");res.end();}}).listen(3000,'192.168.1.16');
