在express.js上使用带有Redis适配器的socket.io：如何将所有套接字会话放入房间？

Question

我想将所有套接字的会话检索到房间中。

我与express-session在socket.io会话中共享了express-socket.io-session。

我的仆人：

import * as sharedsession from 'express-socket.io-session';
import * as session from 'express-session';
import * as connectRedis from 'connect-redis';
import * as express from 'express';
import * as SocketIO from 'socket.io';
import * as redisSocket from 'socket.io-redis';

// redis optinon
const redisOption = { port: 'XXX' };


// express.js
const app = express();

// create the redis store for the express session
const RedisStore = connectRedis(session);
const expressSession = session({
      name: 'SESSIONID',
      store: new RedisStore(redisOption),
      secret: 'as54f6a65sf4fa',
      resave: false,
      saveUninitialized: false,
      cookie: { secure: true }
});
// set the session into express
app.use(expressSession);


// socket.io
const io = SocketIO(httpServer, {path: '/api/socket.io', origins: '*:*'});
// se the adapter for socket io
io.adapter(redisSocket(redisOption));
// share the express session with socket io
io.use(sharedsession(expressSession, {autoSave: true}));

// just for test, join all socket into a room 'foo'
io.on('connection', (client) => {
    client.join('foo');
});


// start the express server
app.listen(3000);

我试图将用户会话检索到会议室中

io.in('foo').clients((err, clients) => {
    for (let i = 0, e = clients.length; i < e; i++) {
        const client = clients[i]; // socket id
        // HOW GET THE SOCKET SESSION?
    }
});

我也尝试过

// this works only for the current instance, don't return all sockets into the redis adapter
const sockets = io.sockets.adapter.rooms['foo'].sockets;
