創建一個最簡單的服務器

var http = require(‘http‘);
var server = http.createServer(function (request, response) {
    response.end(‘ok‘);
});
server.listen(8080);

啟動後在瀏覽器輸入http://127.0.0.1:8080 後如圖所示

我們可以再復雜點，調用fs模塊打開index.html，啟動瀏覽器就會去加載index.html頁面的內容

var http = require(‘http‘);
var fs = require(‘fs‘);
var server = http.createServer(function (request, response) {
    fs.readFile(‘index.html‘, ‘utf-8‘, function (err,data) {
        response.end(‘ok‘);
    });
});
server.listen(8080);　　

監聽代碼也可直接鏈式調用

var http = require(‘http‘);
var fs = require(‘fs‘);
var server = http.createServer(function (request, response) {
    fs.readFile(‘index.html‘, ‘utf-8‘, function (err,data) {
        response.end(‘ok‘);
    });
}).listen(8080);
