我是 session 新手，这是我的第一个认真的编码项目。我已经尝试了一百万次，但我不明白为什么 session 不能通过不同的路线持续下去。当我从两条路由记录 req.session.id 时，它给了我两个不同的 id，而它应该是相同的。
const express = require('express');
const cors = require('cors');
const mongoose = require('mongoose');
const session = require('express-session');
const bcrypt = require('bcrypt');
let User = require('./models/user.model');
const MongoStore = require('connect-mongo')(session);
require('dotenv').config();
const app = express();
const port = process.env.PORT || 5000;
app.set('trustproxy', true);
app.use(cors(corsOptions));
app.use(cors());
app.use(express.json());
const uri = process.env.ATLAS_URI;
mongoose.connect(uri, { useNewUrlParser: true, useCreateIndex: true, useUnifiedTopology: true });
const connection = mongoose.connection;
connection.once('open', () => {
console.log("MongoDB database connection established successfully")
})
app.listen(port, () => {
console.log(`Server is running on port: ${port}`);
});
const SESS_NAME = 'session';
const SESS_SECRET = 'youshouldchangethis'
const IN_PROD = false;
app.use(session({
name: SESS_NAME,
resave: false,
store: new MongoStore({ mongooseConnection: mongoose.connection }),
saveUninitialized: true,
secret: SESS_SECRET,
proxy: true,
cookie: {
sameSite: true,
secure: IN_PROD,
}
}));
登录路由创建 session (此时 session 存储在 Mongodb 中)，然后 react 重定向到仪表板，其中 req.session 返回未定义，我无法访问该 session 。这是登录和仪表板路线。非常感谢任何帮助!
app.post('/login', (req, res) => {
console.log("in login post");
User.findOne({ email: req.body.email })
.then(user => {
bcrypt.compare(req.body.password, user.password, function (err, result) {
if(result == true){
req.session.userId = user._id;
console.log(req.session.id);
res.send(user);
} else {
res.send('Authentication Failed');
}
})
})
.catch(err => res.send('Authentication Failed'));
});
// Dashboard Router
app.get('/dashboard', (req, res) => {
if (req.session.userId){
User.findOne({ email: req.session.user.email }) // FIX: not able to find session / user
.then(user => {
console.log("found user")
// req.session.user = user;
res.send(user);
})
.catch(err => {
//req.session.reset();
res.send(err);
})
} else {
console.log(req.session.id);
}
});
最佳答案
我在express-session中找到了这个文档，也许这就是您正在寻找的:
Session.save(callback)
.... There are some cases where it is useful to call this method, for example, redirects, long-lived requests or in WebSockets.
req.session.save(function(err) {
// session saved
})
