插座室不起作用

Question

我正在尝试使用socket.io房间的概念创建一个私人聊天室。当用户点击另一个用户的名字时，会开始比较，如果有一个房间同时包含两个用户，那么它将加入房间，否则将创建一个包含两个用户的新房间。 当消息到达时，消息被发送到相应的房间，但我的代码不起作用：比较完成，找到相应的ID，但是为连接到tchat的每个人发送消息。

这是服务器的代码

var express = require('express');
var app = express();
var server = require('http').createServer(app);
var io = require('socket.io').listen(server);

var port = process.env.PORT || 8080;

//session with socket.io
io.use(function(socket, next) {
  sessionMiddleware(socket.request, {}, next);

io.on('connection', function(socket) {

      socket.on('startchat', function(name) {
