Nodejsモジュールの呼び出し操作例分析

本明細書の例は、Nodejsモジュールの呼び出し動作を説明する.皆さんに参考にしてあげます.具体的には以下の通りです.
User.js

//    
function User(id, name, age) {
  this.id = id;
  this.name = name;
  this.age = age;
  this.enter = function () {
    console.log(this.name + "       ");
  }
}
/*
function User() {
  this.id;
  this.name;
  this.age;
  this.enter = function() {
    console.log(this.name + "     ");
  }
}
*/
module.exports = User;

Techer.js

var User = require('./User');
function Teacher(id, name, age) {
  User.apply(this, [id, name, age]);//    
  this.teach = function(res) {
    res.write(this.name + "  ");
  }
}
module.exports = Teacher;

modal call_1.js

//----------------------n3_modalcall.js     -------------
var http = require('http');
var User = require('./model/User');
http.createServer(function (request, response) {
  response.writeHead(200, {
    'Content-Type': 'text/html; charset=utf-8'
  });
  if (request.url !== "/favicon.ico") { //   2   
    user = new User(1, "jack", 20);
    //user.id = 1;
    //user.name = "  ";
    //user.age = 20;
    user.enter();
    response.end('');
  }
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');

modal call_2.js

//----------------------n3_modalcall.js-------------
var http = require('http');
var Teacher = require('./model/Teacher');
http.createServer(function(request, response) {
  response.writeHead(200, {
    'Content-Type': 'text/html; charset=utf-8'
  });
  if(request.url !== "/favicon.ico") { //   2   
    teacher = new Teacher(1, "JackLi", 20);
    teacher.enter();
    teacher.teach(response);
    response.end('');
  }
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');

ここで述べたように、皆さんのnodejsプログラムの設計に役に立ちます.
