nodejs http模块

创建一个最简单的服务器

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

启动后在浏览器输入http://127.0.0.1:8080 后如图所示

我们可以再复杂点，调用fs模块打开index.html，启动浏览器就会去加载index.html页面的内容 

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);　　

 监听代码也可直接链式调用

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);
