6-最基础的服务-es6写法

创建server.js

'use strict';
//http模块
var http = require('http');
//封装的方法
var handlers = require('./handlers');

//创建服务
var server = http.createServer(function(request, response) {
	//url地址
	var url = request.url;

	if(url === '/'){
		handlers.homepage(request, response);
	}else if (url === "/profile") {
	    handlers.profile(request, response);
	} else {
	    handlers.notFound(request, response);
	}
});
//端口3000
server.listen(3000);
console.log('start 3000');

handlers.js

'use strict';
//首页
exports.homepage = function(request, response){
	response.setHeader('Content-Type', 'text/html');
	response.end('<h1>helloworld</h1>')
}
//一个接口
exports.profile = function(request, response){
	var profile = {
		name : 'will',
		age : 35
	}
	response.setHeader('Content-Type','application/json');
	response.end(JSON.stringify(profile));
}

//404
exports.notFound = function(request, response) {
  response.statusCode = 404;
  response.setHeader("Content-Type", "text/html");
  response.end("<h1>404 Not Found!</h1>");
}

es6写法

1.下载babel-register

npm install babel-register -S

2.下载babel-preset-es2015

npm install babel-preset-es2015 --save-dev

main.js

require('babel-register');
require('./src/server');

server.js

import http from 'http';
import { homepage, notFound } from './handlers';

const server = http.createServer((request, response) =>{
	homepage(request, response);
});

server.listen(3000);
console.log('listen 3000');

handlers.js

export function homepage(request, response){
	response.setHeader("Content-Type", "text/html");
    response.end("hello world");
}

export function notFound(request, response){
	response.setHeader("Content-Type", "text/html");
    response.end("404");
}
