nodejs session MD5加密学习笔记

nodejs session应用

node中 需要引用express-session ，

var session = require('express-session')();

读取和存储都用req.session

var express = require('express');
var app = express();
var session = require("express-session");

//使用中间件

app.use(session({
    secret:'keyboard cat',
    resave:false,
    saveUninitialized:true,
}));

app.get('/',function(req,res){
    if(req.session.login =="1"){
        req.send(req.session.name+'已经登录');

    }else{
        req.send('未登录');
        
    }
});
app.get('/login',function(req,res){
    req.session.login = "1";
    req.session.name = 'sunling';
    res.send('登录成功');
});
app.listen(3000); 

 MD5加密

node中 自带了一个加密模块，crypto模块，加密是单向的

var crypto = require('crypto');

首先创建hash，然后update,digest

var md5 = crypto.createHash('md5');

var password = md5.update(fields.password).digest('base64');
