Question

是否有任何工作示例存储会话并将所有会话用于所有打开的窗口，让一个用户只需连接一个房间一次？

这个应用程序将获得phpsessions作为node.js会话，但我不知道如何只让一个人访问此聊天应用程序

//define what we need
    var express = require('express'),
        app = express(),
        memcache = require("memcache"),
        http = require('http'),
        server = http.createServer(app),
        io = require('socket.io').listen(server),
        co = require("./cookie.js"),
        php = require('phpjs'),
        codein = require("node-codein");


    // answer all request from users and send them back index.html for root access
    app.get('/', function (req, res) {
      res.sendfile(__dirname + '/index.html');
      var cookieManager = new co.cookie(req.headers.cookie);

      //using memcache as our session store
      var client = new memcache.Client(11211, "localhost");
      //connect to memcache client
      client.connect();
      //get our cookie sessions
        user = client.get("sessions/"+cookieManager.get("sec_session_id"), function(error, result){
                var session = JSON.parse(result);
                            //get just username from sessions(sessions store name and family and chat username in this case)
                user = JSON.parse(session.name);
                user = user.username;
                            //use this function to pass our chat username to our function
                storeUsername(user);
        });

    });

    function storeUsername(user){
    // usernames which are currently connected to the chat

    var usernames = {};
    io.sockets.on('connection', function (socket) {
        usernames[socket.id] = socket;
        // when the client emits 'sendchat', this listens and executes
        socket.on('sendchat', function (data) {
            // we tell the client to execute 'updatechat' with 2 parameters
            io.sockets.emit('updatechat', socket.username, data);
        });

        // when the client emits 'adduser', this listens and executes
        socket.on('adduser', function(username){
            // we store the username in the socket session for this client
            socket.username = user;
            // add the client's username to the global list
            // echo to client they've connected
            if(php.in_array(socket.username,usernames)){
                delete usernames[socket.username];
            }else{
                usernames[user] = user;
                console.log('not exist');
            socket.emit('updatechat', 'SERVER', 'you have connected');
            // echo globally (all clients) that a person has connected
            socket.broadcast.emit('updatechat', 'SERVER', username + ' has connected');
            // update the list of users in chat, client-side
            io.sockets.emit('updateusers', usernames);
            }
        });

        // when the user disconnects.. perform this
        socket.on('disconnect', function(){
            // remove the username from global usernames list
            delete usernames[socket.username];
            // update list of users in chat, client-side
            io.sockets.emit('updateusers', usernames);
            // echo globally that this client has left
            socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
        });
    });
    }
    server.listen(3000);

一切正常，发送数据的用户已定义，但当我在另一个标签中访问此网站时，我将另一次连接到socket.io服务器

Answer 1

您的意思是在浏览器标签之间共享websocket吗？

Sharing websocket across browser tabs?

但为什么你需要共享套接字？我为论坛开发了一个node.js聊天，我们不关心用户有多少个套接字。我们只有一个“用户”对象，其中包含一个套接字列表。我们不关心套接字来自firefox，来自Android应用程序......这不是问题。当我们需要向用户发送信息时，我们会将其发送到每个套接字。

你可以试试这个。它使用express和socket.io https://github.com/gravityonmars/Balloons.IO

使用会话来验证用户socket.io express node.js的工作聊天示例
