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);
