1.10 创建客户端 🎉

//client.js
var http = require('http');
// 用于请求的选项
var options = {
    host: 'localhost',
    port: '3030',
    path: '/'
};
// 处理响应的回调函数
var callback = function (response) {
    // 不断更新数据
    var body = '';
    response.on('data', function (data) {
        body += data;
    });
    response.on('end', function () {
        // 数据接收完成
        console.log(body);
    });
}
// 向服务端发送请求
var req = http.request(options, callback);
req.end();

//server.js 
const http = require('http')
const url = require('url')
const server = http.createServer(function (req, res) {
    const { pathname } = url.parse(req.url)
    if (pathname == '/') {
        res.write('hello')
        res.write('world')
        res.end()
    }
})
server.listen('3030', function () {
    console.log('服务器正在监听3030端口')
})
