node基础04：模块调用

1.模块调用

　　node遵循AMD规范

//server.js
var http = require("http");
var Teacher = require("./teacher");
http.createServer(function(request, response){
    response.writeHead(200, {"Content-Type":"text/html; charset=uf-8"});
    if (request.url!=="/favicon.ico") {
        let teacher = new Teacher(1, 'gaoxiong', 24);
        teacher.job();
        response.end();
    }
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');

//user.js
function User(id, name, age){
    this.id = id;
    this.name = name;
    this.age = age;
    this.job = function(){
        console.log('learning');
    }
}
module.exports = User;

//teacher.js
var User = require("./user");
function Teacher(id, name, age){
    User.apply(this, [id, name, age]);
    this.job = function(){
        console.log('teaching:'+this.name);
    }
}
module.exports = Teacher;
