Socket.IO

问题 I have a simple chat application based on nodejs and socket io. Works fine locally. But i am facing issues in deploying it to openshift. I have read and implemented almost all related threads on Stack Overflow. No progress yet. Client Side(index.html): <script src="/socket.io/socket.io.js"></script> var socket = io.connect("http://www.abcd.com:8000/"); where 'abcd' is an attached domain name to the openshift app. Server Side(index.js): //Express initializes app to be a funciton handler that

问题 I am creating a Node.js chat using socket.io The problem is that when I see the console.log of history I see an array with A LOT of nulls and at the end my history entries [null,null,null......[ { username: 'Nobody Example', message: '231', date: '03/21/2013 14:23:58' } ]] How come these nulls are in the array? Here is a part of my code. var history = []; io.sockets.on('connection', function (socket) { socket.on('send', function (message) { var date = time(); io.sockets.in(socket.room).emit(

问题 Now, after some hours of playing around with nodejs and socket.io, I'm getting a couple more problems - one being, that I need to get the sessionID inside node.js, whitout using app.get('/' ... - since that event doesnt seem to fire when socket.io connects, it only fires .on('connection', function( ... var express = require('express')() express.set('port', process.env.PORT || 8080) var server = require('http').createServer(express) var socket = require('socket.io').listen(server) server

问题 I am trying to connect Gottox (https://github.com/Gottox/socket.io-java-client) with socket.io (1.0.4)(http://socket.io/) but unable to connect I think Gottox doesn't work with latest socket.io. Is there any other Java/Android library that I can use to make socket connections between socket.io and android native application. I am using node.js at server side. 回答1: Looks like https://github.com/nkzawa/socket.io-client.java supports the latest socket.io 1.x version. I haven't tried it yet. 来源：

问题 Unfortunately socket.io developer team decided to deprecate functions set() and get(). The problem is that these two functions allowed us to save variable into session. So my question is : What is the equivalent of the folloing code on socket.io 1.0.5 ? socket.set('mySessionVar', 'myValue'); socket.get('mySessionVar', function (error, mySessionVar) { console.log('I have a super variable save in the session : '+mySessionVar); socket.emit('mySessionVar', mySessionVar); }); Thank you for your

问题 I have a model named Groupfeed which looks like this module.exports = { schema:true, attributes: { groupid: { model:'groups', required:true }, postid: { model:'post', required:true }, objectid: { model:'objects', required:true }, } }; On the client side I can subscribe to the Groupfeed model using io.socket.get('/groupfeed') which is done automatically by the blueprint api and then io.socket.on('groupfeed',function(obj){console.log(obj)}) would give me updates on the model changes when I

问题 I am developing chat application, using node.js socket.io module on a server, and javascript on a client. As it become more complex, I become tired to test different usage scenarios by clicking across browsers. At now I use different browsers in order to separate cookies. So in Firefox there is one chat participant, in Opera - second, etc. Therefore my question is: Can I automate this somehow? I've heard about headless testing engines like Phantom JS, Selenium WebDriver, but I don't know how

问题 Currently, i have created an application in node.js to send notification to all client using socket.io with mysql. So any change in my mysql database will be notified to the multiply clients through socket.io instantly. The application work charm. The problem i'm facing is related to performance issue. My browser get the constant push notification from the server, which slows down the performance of my browser. I/Client need to get the notification only on the database change, rest of the

问题 I have the following code when a user disconnects. I want to emit a signal with the room name and user name. client.get('nickname', function(err, name) { client.get('room', function(err2, room) { io.sockets.in(room).emit('disconnect', name); }); }); My question is, is there any way to avoid wrapping the .get calls like this? For my application, they are going to add up quickly. Can I get more than one value from one get() command? Or am I just handling this all wrong? 回答1: If you need to get

问题 I'm currently looking to offer push notifications to an iphone and android app I'm working on. I took a look at the push notification services and they are very expensive so, I'm looking to run my own using socket.io. I guess my question is, how demanding on the server are push notifications? Do I need a ton of bandwidth or some specific server setup? I haven't used push notifications before to estimate the amount I would need sadly. Currently I'm using Nodejitsu for my nodejs app and plan to
