Socket.IO

问题 I'm about to write a very simple iOS application. I want the application to connect to a server by using Socket.IO. I've already installed Socket.IO with Cocoapods for my project and everything went well. The problem is after I run my server and then the application simulator, the application doesn't get connected to the server. I don't get any kind of error message or something like that but the server should print a message on the console/terminal when a socket is being connected. This is

问题 This is my node server var io = require('socket.io').listen(8889); io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event', function (data) { console.log(data); }); }); I am trying to connect to this node server from client side with the help of socket.io.js I dont have any problem with the connection My requirement is that I want to create a TCP connection to which clients can connect But how can I know and confirm the server is a

问题 I'm trying to implement a multiplayer feature to my game. I'm using node.js for this. When one person connects, an image is supposed to be loaded to the browser. Instead it loads two images. Heres is part of my class var count = 0; //Keep track of which player we're oparating on function Car(id){ var that = this; //Reference to 'this' this.loadHero = function(){ that.id = document.getElementById(id); //Store the id of our charakter $(that.id).css({"display" : "block"}); } } node.js on client

问题 Is there any way to get a list of all the namespaces registered on the socket? For example, suppose some client connects to a namespace: `socket = io('/some-nsp'); They are now in a namespace automagically because the socket.io does not prevent creating random namespaces. If I want to go through the list of all existing namespaces and disconnect those users, how could I get such a list. I've tried io.nsps , but this just is a circular list of junk. Is there an "official" way to get a list of

问题 I am trying to access the session from sockets, but can't seem to make a connection. Without fail, authorization fails and I get the fail callback with the following message: failed connection to socket.io: No session found I will place all my code here so that it might be easier to spot what I'm doing wrong. var express = require('express'); var app = express(); var http = require('http'); var socketio = require('socket.io') var passportSocketIo = require('passport.socketio'); var port =

问题 I am storing username/SocketID pairs in redis store for my socket.io chat application. When the user disconnects i need to remove the username/socketID pair from the redis store. I have seen how to get the value from a key but never a key from a value. Is it possible? or either way how can i delete the key/value pair from just the value. Here's my code For adding to store on connect socket.on('username', function (username) { client.set(username, socket.id, function (err) { console.log

问题 Relating to a previous question I asked, I am building a Windows 8 c++ App that requires me to connect to a Node.js server running socket.io. Does socket.io use any sort of special protocol on top of websockets? When I just do a dry connection, I get an error "HTTP Invalid Response." I see a number of c++ websocket implementations, but I'm having a bit of a hard time trying to translate those concepts into the Windows 8 websocket implementation. 回答1: Check this implementation for windows

问题 I'm new to NodeJS and found it very interesting. I'm not having much problems with building servers with NodeJS. But when I went to develop a web browser-client, I came to know about Socket.IO. But I'm very much confused about this. Can we develop web client applications without using Socket.IOS for NodeJS servers? Is there support for websockets in NodeJS without Socket.IO? 回答1: This question is old, but for future references. Socket.IO is famous, and for node stream https://github.com

问题 I'm using laravel 5.3 + passport for authorization, Laravel is my back-end API which is restful . front-end is written in angular.js which communicate with API with rest requests. For Real-time notifications, I've used laravel broadcasting events + redis , and socket.io for socket server and socket client in angular.js. I want to authorize these events and I've done it far as I could : BroadcastServiceProvider : public function boot() { Broadcast::routes(['middleware' => ['auth:api']]);

问题 I would like to use socket.io to keep track of daily active users of an application. My socket connection looks like this: let visitorData = {}; io.on('connection', (socket) => { socket.on('user', (data) => { visitorData[socket.id] = data; }) socket.on('disconnect', () => { delete visitorData[socket.id] }) }) I would like to be able to incorporate existing Node/Express routes and the data received to socket connections. In particular, how would I handle a POST to a /login endpoint to
