一：复制官网的代码，建立一个简单的服务器
const http = require(‘http‘);const hostname = ‘127.0.0.1‘;const port = 3000;const server = http.createServer((req, res) => { ?res.statusCode = 200; //返回的状态码 ?res.setHeader(‘Content-Type‘, ‘text/plain‘); ?//返回类型为纯文本 ?res.end(‘Hello World\n‘);});server.listen(port, hostname, () => { ?console.log(`Server running at http://${hostname}:${port}/`);});二：了解nodejs的模块
三：创建一个简单的校园模块:
1:添加学生的模块: students.js
function add(name) {console.log(‘add student‘+ name)}exports.add = add2:添加老师的模块: teacher.js
function add(name) {console.log(‘add teacher‘+ name)}exports.add = add3:添加班级的模块: klass.js
// 使用模块之前需要requirevar student = require(‘./student‘) ?//将模块对象赋值给局部变量var teacher = require(‘./teacher‘)function add(teacherName, students) {teacher.add(teacherName)students.forEach(function (item, index) {student.add(item)})}exports.add = add4:添加学校的模块: index.js
var klass = require(‘./klass‘)exports.add = function (klasses) {forEach(function (item, index) {var _klass = itemvar teacherName = item.teacherNamevar students = item.studentsklass.add(teacherName, students)})}
