初学node.js-nodejs中实现删除用户路由

一、users_model.js 功能:定义用户对象模型

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:为Express服务器实现删除用户路由

var crypto=require('crypto');

var mongoose=require('mongoose'),User=mongoose.model('User');

function hashPW(pwd){

    return crypto.createHash('sha256').update(pwd).

    digest('base64').toString();

}

//实现删除用户路由

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>用户修改</title>

<link rel="stylesheet"type="text/css" href="/static/css/styles.css" />

  <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">用户修改</p>

   <form method="POST" action="/user/update">

    <label>用户名:</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>肤色:</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="删除用户">

  </form>

  <hr><%=msg%>

  <hr>{{error}}

</body>

</html>

四、routes.js 功能:为Express服务器实现处理Web请求路由

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);
