Question

我遇到了问题。我设置了一个会话，我创建了这个对象：

req.session.userId = user.id

但是当我重定向到另一个页面时，这个userId对象在那里是未定义的。我发现它是由重定向引起的。你知道如何在重定向后使我的req.session.userId值可用吗？

您可以按照以下方式创建会话： -

的package.json

{
  "name": "server",
  "version": "0.0.0",
  "description": "it is a server",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "dependencies": {
    "express": "~4.0.0",
    "body-parser": "~1.0.1",
    "express-session": "^1.0.2",
    "connect": "^2.13.0",
    "method-override": "~1.0.0"
  },
  "author": "SM@K",
  "license": "ISC"
}

index.js

var express = require('express');

var session = require('express-session');
var MemoryStore = require('connect').session.MemoryStore
// create our app
var app = express();

app.use(session({
    secret: "secret",
    store: new MemoryStore({reapInterval: 60000 * 10})
}));


app.get('/', function(req, res) {
    req.session.from_session = 10;
    res.redirect('/session');

});

app.get('/session', function(req, res) {
    res.send("Comming From Session: " + req.session.from_session);
});

app.get('/session-test', function(req, res) {
    res.send("Test Session: " + req.session.from_session);
});

app.listen(3001);
console.log('listen 3001');
