javascript - session 不工作 + 快速

Question

我在我的应用程序中使用快速 session 。我尝试过的是 (POC):.

server.js

    app.use(session({
        secret: 'pal!lap789',
        // create new redis store.
        store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  260}),
        saveUninitialized: false, 
        key: 'user_sid',   
        resave: false,
        cookie: { secure: false, httpOnly: false }
    }));
app.get('/abcd', sessionChecker, function(req, res){
    res.send("hiiiii");
});

app.get('/session', (req, res) => {
    req.session.user = "subbuvlb@gmail.com";
    res.send("hgdhjdgjds")
});

它工作正常，

但是当我尝试与我的项目集成时，它不起作用。

app.use(session({
            secret: 'pal!lap789',
            // create new redis store.
            store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  260}),
            saveUninitialized: false, 
            key: 'user_sid',   
            resave: false,
            cookie: { secure: false, httpOnly: false }
        }));
var usersRouter = require('./router/users');
app.use('/users', usersRouter);

router/user.js

const express = require('express');  -------------> New express instantiated.
const router = express.Router();
router.post('/register', (req, res, next) => {
req.session.user = "emailid"
});

我想要实现的是必须检查每个请求是否存在用户 session ，

所以我修改了我的 server.js 文件如下:

    app.use(session({
                    secret: 'pal!lap789',
                    // create new redis store.
                    store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  260}),
                    saveUninitialized: false, 
                    key: 'user_sid',   
                    resave: false,
                    cookie: { secure: false, httpOnly: false }
                }));
        var usersRouter = require('./router/users');
        app.use('/users', usersRouter);
    var sessionChecker = (req, res, next) => {
console.log(req.session.user) --------------------------->Undefined
      if (req.session.user && req.cookies.user_sid) { 
          next();
      } else {
          res.redirect('/login');
      }    
    };
var usersRouter = require('./router/users');
app.use('/users',sessionChecker, usersRouter);

如果我在 server.js 中指定路由器文件，为什么会出现 req.user.undefined。我想我解释清楚了，准备好在需要时提供更多意见。请提供你的想法。提前致谢。

在你的server.js文件中定义全局变量

global.express = require('express'); 
global.app = express();
global.session = require('express-session');

 app.use(session({
                    secret: 'pal!lap789',
                    store: new redisStore({ host: 'localhost', port: 6379, client: client,ttl :  260}),
                    saveUninitialized: false, 
                    key: 'user_sid',   
                    resave: false,
                    cookie: { secure: false, httpOnly: false }
                }));

    var sessionChecker = (req, res, next) => {

      if (req.session.user && req.cookies.user_sid) { 
          next();
      } else {
          res.redirect('/login');
      }    
    };

var usersRouter = require('./router/users');
app.use('/users',sessionChecker, usersRouter);

在你的router/user.js

const router = express.Router(); // use global express defined in server.js

router.post('/register', (req, res, next) => {
  req.session.user = "emailid"
});
