websocket server, storing the data

由 别说谁变了你拦得住时间么 提交于 2021-02-20 18:46:57
问题 Lets say that i make a websocket server chat (node.js + socket.io). How would i store the chat messages, so that when a "new" user joins the chat, he will be seeing old chat messages, and not just the ones which has been sent while hes in the chat. Should the data be stored in variables in the server? Something like: var io = require('socket.io').listen(80); var saveData = { }; io.sockets.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event',

由 醉酒当歌 提交于 2021-02-20 10:24:39
问题 My API Manager tool mandates that i should pass the Authorization Bearer access token with the websocket invocation call. They are providing samples of java code where they do that. The bearer token is set like ("Authorization", "Bearer e2238f3a-e43c-3f54-a05a-dd2e4bd4631f") .How can i do that in javascript? // HttpResponseDecoder to WebSocketHttpResponseDecoder in the pipeline. final WebSocketClientHandler handler = new WebSocketClientHandler( WebSocketClientHandshakerFactory .newHandshaker

问题 Having gone through multiple posts on stack I still couldn't find a right answer. Checked the documentation on CORS extension as well. I have the following server code up and running: var WebSocketServer = require("ws").Server var http = require("http") var express = require('express') var cors = require('cors') var app = express(); app.use(cors()); var port = process.env.PORT || 9000 var server = http.createServer(app) server.listen(port) var count = 0; var clients = {}; var rooms = {}; var

Require (the same instance of) socket.io in multiple modules

由 假如想象 提交于 2021-02-19 08:42:06
问题 I am a bit confused, about how to require and use modules in Node.js. My scenario is the following: I wrote a complete server in one single file, which uses Socket.io for realtime communication. Now the index.js became pretty big, and I want to split the code into several modules to make it more managable. For example I have some functions for serving a Survey to the clients, and getting back their answers. I put all those functions in a seperate module, and require it in the index.js. Works

Can I start a socket.io/websocket server in browser?

由 徘徊边缘 提交于 2021-02-19 05:34:00
问题 There question about this before, the answer is no. But now, with browserify/webpack, can I just write code like I would on server and it will run in browser, or is there any restriction that would make this impossible? 回答1: No, you cannot. Starting a server in a browser requires access to low level functionality that simply to does not exist in a browser. Browserify cannot add fundamental low-level features to the browser that it does not have that would require additional native code

How can I redirect all clients to another page with socket.io?

由 人走茶凉 提交于 2021-02-19 01:35:30
问题 I am working on an online multiplayer cards against humanity game (React on the front, React router for redirecting, and Node in the back) I am trying to redirect all clients in a "lobby", or room, when one user in the lobby clicks "start", but right now only the user that clicks start is redirected. The idea is somebody will set up a new game, which will have a unique pin, where after you create the game and select your avatar, others can use that pin the join the lobby (this part is working
