问题 I'm trying to switch from single mysql-queries to mysql-pool connection, so users can share one mysql-connection, but I'm not familiar with this at all (also new to nodejs/socket.io). The following code is what I've done so far to send data every second to the socket in an array: var port = process.env.OPENSHIFT_NODEJS_PORT || 8000, ip = process.env.OPENSHIFT_NODEJS_IP || '127.0.0.1', app = require('http').createServer(handler), fs = require('fs'), request = require('request'), mysql =

Socket.io connect event not firing

由 放肆的年华 提交于 2019-12-25 09:50:11
问题 This is my first time working with node.js/socket.io and I'm having a little trouble with the 'connect' event firing for all sockets. I followed the chat application example and then tried to add a feature where instead of displaying in the console when a user connects or disconnects, I would display it on-screen. The disconnect event is firing for all tabs (if I have multiple tabs open to the chat application), but the connect event only seems to fire for the current tab. Server (index.js)

Swift Socket.io the event sent right after connection is not executed

问题 So I am trying to send (emit) an event right after the connection. I am building a chat app, and the only issue I have is that when the user disconnected and connect to the server again, other clients are not informed the reconnected client is back (I think it is because my userlist data at the server end is not updated when the reconnected client is back) So I'm trying to send an event right after the connection to update the userlist data at the server end. But seems like the event is not

Installing socket.io C++

问题 I try to work with socket.io in C++ but I can't seem to get the example running. First it asked me to convert the project to my visual studio (which is 2015). So I did that. Then it was missing libraries offcourse (boost, websocket++, rapidjson). So I added them to the additional libraries in the project settings. Then it was searching for boost.lib. Boost.lib doesnt exist in the boost library I installed on my pc, so I deleted it from the dependency list. I figured I already included boost,

问题 I want to use the websocket in my RN project. And I did it using the ws at server side and the RN built-in websocket implementation. But it seems not so convinient since I use socket.io before. So I tried to use socket.io: In RN: import './userAgent' import io from "socket.io-client/socket.io" In component: componentDidMount() { this.socket = io('https://localhost:4080',{jsonp: false}); this.socket.on('hello', (msg) =>{ this.setState({response:msg}) }); } In the server: io.on('connection',
