Question

我有一个带有不同事件的nodejs聊天服务器 “连接”，“sendchat”，“switchRoom”......

///////////////////////////////////////////////////////////////
// SERVER SETUP


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

server.listen(1214);



var admin_name = '<font color="red">*Admin*</font>';
var users;
// rooms which are currently available in chat
var rooms = ['public'];

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

// when the client emits 'adduser', this listens and executes
socket.on('adduser', function(username, password){
    getLogin(username, password, socket)
});

// when the client emits 'sendchat', this listens and executes
socket.on('sendchat', function (data) {
    insertMess(socket.username, data, socket.room);
    var nd = data.split(">");
    if(nd[0] == 'cmd')
    {
        switch(nd[1])
        {
            case 'admin-mess':
                //Return message to user
                socket.emit('updatechat', admin_name, '<font color="red">your message was sent to all rooms.</font><br>'+nd[2]);
                //broadcast message to all rooms
                for(var i=0; i<rooms.length; i++)
                {
                    socket.broadcast.to(rooms[i]).emit('updatechat', '<font color="red">'+admin_name+'</font>', '<font color="red">'+nd[2]+'</font>');
                }   
            break;
            default:
                socket.emit('updatechat', admin_name, 'you try to send a wrong command...');
            break;
        }

        return;
    }

    // we tell the client to execute 'updatechat' with 2 parameters
    io.sockets.in(socket.room).emit('updatechat', socket.username, data);
});

socket.on('switchRoom', function(newroom){
    console.log('--> '+socket.username+" joined the room : "+newroom);
    // leave the current room (stored in session)
    socket.leave(socket.room);

    //get userlist of the room
    users = getRoomUsers(socket.room);
    //update userlist in room
    socket.broadcast.to(socket.room).emit('updateusers', users);

    // join new room, received as function parameter
    socket.join(newroom);
    socket.emit('updatechat', admin_name, 'you are connected to "'+ newroom+'"');
    // sent message to OLD room
    socket.broadcast.to(socket.room).emit('updatechat', admin_name, socket.username+' has left this room');
    // update socket session room title
    socket.room = newroom;
    socket.broadcast.to(newroom).emit('updatechat', admin_name, socket.username+' has joined this room');
    socket.emit('updaterooms', rooms, newroom);
    //socket.broadcast.to(newroom).emit('updateuserlist', socket.clients(newroom));


    users = getRoomUsers(socket.room);
    //update userlist in room
    socket.broadcast.to(socket.room).emit('updateusers', users);
    //update userlist for client
    socket.emit('updateusers', users);


});

// when the user disconnects.. perform this
socket.on('disconnect', function(){
    // echo globally that this client has left
    socket.broadcast.emit('updatechat', admin_name, socket.username + ' has disconnected');
    socket.leave(socket.room);
    console.log('<-- '+socket.username+" has disconnected".info);
    //get userlist of the room
    users = getRoomUsers(rooms[0]);
    //update userlist for client
    socket.broadcast.emit('updateusers', users);
});

});

我需要将我的Titanium应用程序（iOs / Android）连接到我的服务器。我的问题是：

如何创建与我的服务器的socket.io连接？
我如何收听套接字事件？
我如何发出事件？

某人可以有一点例子吗？

很多！

您需要客户端库才能连接到服务器。您可以在domain.com/socket.io/socket.io.js上获取它并在本地缓存它。从那里你可以访问全局io然后连接：

var socket = io.connect();

将库复制到您的应用程序中并拥有一个每x天/周提取最新版本的后台服务可能更好。
