經過前面幾次的學習，已經可以做下小功能，今天要實現的是用戶注冊路由。

一、users_model.js 功能:定義用戶對象模型

var mongoose=require('mongoose'),   Schema=mongoose.Schema;var UserSchema=new Schema({   username:{type:String,unique:true},   email:String,   color:String,   hashed_password:String});mongoose.model('User',UserSchema);

二、users_controller.js 功能:為Express服務器實現用戶注冊的路由

var crypto=require('crypto');var mongoose=require('mongoose'),User=mongoose.model('User');function hashPW(pwd){  return crypto.createHash('sha256').update(pwd).  digest('base64').toString();}//實現用戶注冊路由exports.signup=function(req,res){var user=new User({username:req.body.username});user.set('hashed_password',hashPW(req.body.password));user.set('email',req.body.email);user.save(function(err){  if(err){    res.session.error=err;    res.redirect('/signup');  }else{    req.session.user=user.id;    req.session.username=user.username;    req.session.msg='Authenticated as '+user.username;    res.redirect('/');  }});};

三、signup.html 用戶注冊頁面

<!DOCTYPE html><html><head><meta charset="UTF-8"><title>用戶注冊</title><link rel="stylesheet"type="text/css" href="/static/css/styles.css" rel="external nofollow" /></head><body> <div class="form-container"> <p class="form-header">注冊</p> <form method="POST" >  <label>用戶名:</label>   <input type="text" name="username"><br>   <label>密碼:</label>   <input type="password" name="password"><br>   <label>Email:</label>   <input type="email" name="email"><br>   <input type="submit" value="注冊"> </form> </div> <hr> <%=msg %></body></html>

四、routes.js 功能:為Express服務器實現處理Web請求路由

var crypto=require('crypto');var express=require('express');module.exports=function(app){  var users=require('./controllers/users_controller');  app.use('/static',express.static('./static')).  use('/lib',express.static('../lib'));app.get('/signup',function(req,res){  if(req.session.user){    res.redirect('/');  }  res.render('signup',{msg:req.session.msg})});app.post('/signup',users.signup);

頁面效果
