【问题描述】：

我正在尝试将会话存储与 Socket.io 和 passport.js 一起使用

var session = require('express-session');
var cookieParser = require('cookie-parser');
var MongoStore = require('connect-mongo')(session);
var sessionStore = session({
    store: new MongoStore({url: 'mongodb://localhost/RULE'}),
    key: 'express.sid',
    secret: 'Heisenberg'
});

// Socket.io auth
io.set('authorization', passportSocketIo.authorize({
    cookieParser: cookieParser,
    key: 'express.sid',
    secret: 'Heisenberg',
    store: sessionStore,
    success: onAuthorizeSuccess,
    fail: onAuthorizeFail,
}));

我收到此错误： TypeError: auth.store.get is not a function

所以我猜这是 connect-mongo 商店实例的问题，但我不知道如何调试它或问题可能是什么。

好的，所以问题是我使用的是 express session 而不是 MongoStore

var session = require('express-session');
var cookieParser = require('cookie-parser');
var MongoStore = require('connect-mongo')(session);
// sessionStore and expressSesion are now saved distinctly
var sessionStore = new MongoStore({url: 'mongodb://localhost/RULE'});
var expressSession = session({
    store: sessionStore,
    key: 'express.sid',
    secret: 'ThisIsTheSecret'
});

var passportSocketIo = require('passport.socketio');

// Load middlewares
var morgan = require('morgan');

// Use middlewares
app.use(expressSession);

// Socket.io auth
io.set('authorization', passportSocketIo.authorize({
    cookieParser: cookieParser,
    key: 'express.sid',
    secret: 'ThisIsTheSecret',
    store: sessionStore, // here we pass the MongoStore, not the expressSession
    success: onAuthorizeSuccess,
    fail: onAuthorizeFail,
}));
