Socket.IO

问题 I have my API hosted on Heroku and the Angular webAPP in other server. I have a problem when integrating socket.io to the API, my calls to the api do not work and I get error 503, caused by some bad configuration of the CORS? app.js (Node.js/Express hosted in heroku server) var express = require('express'); var app = express(); var port = process.env.PORT || 8080; //var port = 3000; // Notification Real Time // http://4dev.tech/2017/12/tutorial-creating-a-realtime-notification-system-in

问题 I want to implement Socket.IO in an Electron app, however I have found no documentation and no examples of how this could work. If someone could explain to me how two or more clients could communicate via the electron app, I would be very grateful! 回答1: You know, the electron app will be running at end user. So you should create Socket server at somewhere sth like Cloud server and your electron app should contain one socket.io client instance. At Socket server const app = require('express')()

问题 I have a route that listens to a particular route id. /** * Chat app routes. */ app.get('/games/:id', gameChatController.chatRoom); Based on the route id I can determine what game the chat is about. My question is how do I use this to pass into socket.io? bin/www /* * setup socket.io, and socket-session */ var socketIO = require('socket.io'); var io = socketIO(server); var SessionSocket = require('session.socket.io'); var sessionSockets = new SessionSocket(io, app.sessionStore, app

TypeError: Failed to execute 'addIceCandidate' on 'RTCPeerConnection': Candidate missing values for both sdpMid and sdpMLineIndex I am using two separate laptops to test the connection and since both remote and local videos are showing, I think that I have

问题 I would like to know if its possible to get active WebSockets of a Website. An example would be: var x = document.findWebSocket() . The websockets would be listed in Chrome under the Network Tab (In the dev tools section). From there the websockets are listed under "WS". I want to be able to do x.emit(..); as well. So far i could only come up with var x = new WebSocket("wss://exampleUrl.com/socket.io/?EIO=3&transport=websocket", "protocol1"); . But this only adds a new Websocket with a

问题 I know there are several questions like this but i can't find one solving my problem for a project which is not in the server root. I have the following situation: I have an Apache server which runs several projects like: 0.0.0.0/project1 0.0.0.0/project2 I added a node.js project let's call it nodeproject . With ProxyPass I am passing requests made to 0.0.0.0/nodeproject to 0.0.0.0:8080 where my node server is running. This is all working fine except the websocket configuration for socket.io

问题 I am trying to run NodeJS behind Apache and so far I am stuck with Socket.io issue.
