使用场景: 聊天室；大量数据常驻交互； 技术栈： Node.js, Vue.js || 原生JS 服务端代码: const app = require('http' ).createServer() const io = require('socket.io' )(app) app.listen( 8877 ) io.on( 'connection', scoket => { let i = 1 const t = setInterval(()=> { i ++ if (i >= 12 ) { clearInterval(t) } // 服务端往客户端发送消息 scoket.emit('news', { hello: 'world', t: new Date().getTime() }) }, 1000 ) // 服务端监听客户端的消息 scoket.on('receiveEvent', data => { console.log( 'receiveEvent: ' , data) }) }) 客户端代码: -- Vue 例子： <template> <div> <p @click="clientToServer">scoket:</p> <p v- for ="(item,index) in arr" :key="index">{{item}}</p> </div> <

How to store client associated data in socket.io 1.0

由 狂风中的少年 提交于 2020-12-29 02:53:45
问题 The docs say socket.io doesn't support .get .set now Is it okay to store client associated data like io.sockets.on('connection', function (client) { client.on('data', function (somedata) { client['data'] = somedata; }); }); in case I need multiple nodes? 回答1: Yes, it is OK to add properties to the socket.io socket object. You should be careful to not use names that could conflict with built-in properties or methods (I'd suggest adding a leading underscore or namescoping them with some sort of

Custom Events in Node.js with Express framework

问题 So, I'd like to know how to create custom events in node.js, and I'm hitting a wall. I'm pretty sure I'm misunderstanding something about how express works and how node.js events work. https://creativespace.nodejitsu.com That's the app. When a user creates a new "activity" (something that will happen many times) they send a POST request. Then within my route, if that POST succeeds I'd like to emit an event, that tells socket.io to create a new namespace for that activity. In my route file:
