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(wù)器實現(xiàn)刪除用戶路由

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(xiàn)刪除用戶路由exports.deleteUser=function(req,res){User.findOne({_id:req.session.user}).exec(function(err,user){if(user){user.remove(function(err){if(err){req.session.msg=err;}req.session.destroy(function(){res.redirect('/login');});});}else{req.session.msg="User Not Found!";req.session.destroy(function(){res.redirect('/login');});}});};

三、user.html

<!DOCTYPE html><html ng-app="myApp"><head><meta charset="UTF-8"><title>用戶修改</title><link rel="stylesheet"type="text/css" href="/static/css/styles.css" rel="external nofollow" /><script src="https://cdn.staticfile.org/angular.js/1.5.8/angular.min.js"></script><script src="/static/js/my_app.js"></script></head><body><div class="form-container" ng-controller="myController"><p class="form-header">用戶修改</p><form method="POST" action="/user/update"><label>用戶名:</label><input type="text" name="username" ng-model="user.username" disabled><br><label>Email:</label><input type="email" name="email" ng-model="user.email"><br><label>膚色:</label><input type="text" name="color" ng-model="user.color"><br><input type="submit" value="Save"></form></div><form method="POST" action="/user/delete"><input type="submit" value="刪除用戶"></form><hr><%=msg%><hr>{{error}}</body></html>

四、routes.js 功能:為Express服務(wù)器實現(xiàn)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.post('/user/delete',users.deleteUser);

五、頁面顯示效果
