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");
