Socket.IO

问题 I have an isolated python script that simply captures data from Twitter's streaming API and then on the receipt of each message, using redis pubsub it publishes to the channel "tweets". Here is that script: def main(): username = "username" password = "password" track_list = ["apple", "microsoft", "google"] with tweetstream.FilterStream(username, password, track=track_list) as stream: for tweet in stream: text = tweet["text"] user = tweet["user"]["screen_name"] message = {"text": text, "user"

问题 I'm doing a chrome extension with socket.io , i have a content script that keep connecting to server to make a real-time chat, but i also want to get some information from server in background page. it works well separately like this in content script var socket = io.connect('http://localhost:3700'); socket.on('dosomething',function(){ console.log("test"); }); in background page var socket = io.connect('http://localhost:3700'); socket.on('dosomething',function(){ console.log("test"); }); but

问题 I have created a TCP server using Node.js which listens to clients connections. I need to transmit data from TCP server to HTTP server again in Node.js possibly through a Websocket ( socket.io ). However, I do not know how to create such connection such that TCP server is able to push data to HTTP server through Websocket. Many Thanks. 回答1: I was trying lot of things to get this work. Most of the time I was relying on socket.io to get this working, but it was just not working with TCP.

问题 Does anyone know how to listen to the mouse events such as CLICK or HOVER so that when I click or hover any element it will happen the same in the second browser? Apologies for not including the code. <script> // creating a new websocket var socket = io.connect('http://localhost:8000'); // on message recived we print the new data inside the #container div socket.on('notification', function (data) { $("p").click(function () { alert("Hello"); //or change the color $(this).css({"color": "red"});

问题 I'm working on a fully js, HTML5 canvas game and want it to be 'real-time'. Based on my research I find out node.js is an exciting prospect, so I configured it on my ubuntu 12 webserver with socket.io, express etc. I'm a programmer, but just a rookie in the world of webserver backends, that's why I ask for your help. I got confused about the overall system model and want to be clarified how it's working. Maybe, I've read too much article in a short time. First of all: I run nginx 1.2.x on my

问题 I'm looking to build a chat/live stream application (video + text chat). I'm not settled on an approach at the moment, but I'm moving forward with one, and I've gotten stuck. I'm trying to grab the video stream using getUserMedia, and send it to my Node.js server over Socket.io. So far I've got the blob url: "mediastream:http://192.168.1.20:3000/1c267861-a2da-41df-9a83-ae69fdfd883b" but I'm not sure how to grab the data from it to send over socket.io. Any help would rock. Server: // server.js

问题 When conjoining socket.io/node.js and redis pub/sub in an attempt to create a real-time web broadcast system driven by server events that can handle multiple transports, there seems to be three approaches: 'createClient' a redis connection and subscribe to channel(s). On socket.io client connection, join the client into a socket.io room. In the redis.on("message", ...) event, call io.sockets.in(room).emit("event", data) to distribute to all clients in the relevant room. Like How to reuse

问题 I have followed Jeffrey way's tutorial. Tutorial: https://laracasts.com/series/real-time-laravel-with-socket-io/episodes/1 this is my index.js var app = require('express')(); var server = require('http').Server(app); var io = require('socket.io')(server); server.listen(3000); app.get('/', function(request, response){ response.sendFile(__dirname+'/index.html'); }); io.on('connection', function(socket){ console.log('A connection is made'); }); Some people say its the version and year.
