node的cookie-parser和express-session

Posted 2020-11-18 l8l8

let express = require(‘express‘);
let cookieParser = require(‘cookie-parser‘);
let expressSession = require(‘express-session‘);
let ejs = require(‘ejs‘);

let app = express();

app.use(cookieParser());//使用时需要调用cookieParser();

app.use(expressSession({
    secret: [‘aaaa‘,‘c‘],//加密字符串，随机抽取
    rolling: true,      //  永远在线隔一段时间去刷新session
    resave: true,       //
    // name: ‘wpwpwp‘,   //更改名称  最外面的 对象中
    cookie:{
        httpOnly: false,   //这个代表 只能在服务器中获取  验证
        maxAge: 1000*5,//时效
        // path: ‘/aa‘
    }
}));

// app.use(function (req, res, next) {
//     if(req.session.name){
//         req.session.name = 1;
//     }
// });

app.get(‘/‘,function (req, res) {
    // //获取session
    // console.log(req.session);
    // //设置session
    // req.session.name = 1;
    // res.send(‘end‘)
    console.log(req.session);
    req.session.num = 1;
    ejs.renderFile(__dirname+‘/template/index.html‘,{},function (err,data) {
        res.send(data)
    })
});

app.listen(3000,function () {
    console.log(‘start‘)
});

利用cookie-session 去判断用户是否登录。使用签名去判断。

let express = require(‘express‘);
let cookieParser = require(‘cookie-parser‘);
let expressSession = require(‘express-session‘);
let fileStore = require(‘session-file-store‘)(expressSession);

let app = express();

app.use(cookieParser());

app.use(expressSession({
    store: new fileStore(),
    secret: [‘aaaa‘,‘c‘],
    cookie:{
        maxAge: 1000*60,
    }
}));

app.get(‘/‘,function (req, res) {
    console.log(req.session);
    //逻辑判断

    //设置session  帮你写到 服务器的内存中
    //又帮你写了一个 cookie携带这session信息
    req.session.num = 1;

    res.send(‘end‘)
});

app.listen(3000,function () {
    console.log(‘start‘)
});
