经过前面几次的学习，已经可以做下小功能，今天要实现的是用户注册路由。
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服务器实现用户注册的路由
var crypto=require('crypto');
var mongoose=require('mongoose'),User=mongoose.model('User');
function hashPW(pwd){
return crypto.createHash('sha256').update(pwd).
digest('base64').toString();
}
//实现用户注册路由
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 用户注册页面
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>用户注册</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">注册</p> <form method="POST" > <label>用户名:</label> <input type="text" name="username"><br> <label>密码:</label> <input type="password" name="password"><br> <label>Email:</label> <input type="email" name="email"><br> <input type="submit" value="注册"> </form> </div> <hr> <%=msg %> </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.get('/signup',function(req,res){
if(req.session.user){
res.redirect('/');
}
res.render('signup',{msg:req.session.msg})
});
app.post('/signup',users.signup);
页面效果
