Nodejs+Socket.io實現通訊執行個體代碼，nodejssocket.io
目錄結構
D:. │ package.json │ server.js │ └─public index.html socket.io.js
需要的條件
socket.io.js存在於socket.io-client
socket.io存在於socket.io
示範的功能
服務端
server.js
var express = require('express'); var app = express();var server = require('http').createServer(app);var io = require('socket.io')(server);app.use('/', express.static(__dirname + '/public')); server.listen(80);//socket部分io.on('connection', function(socket) { //接收並處理用戶端的hi事件 socket.on('hi', function(data) { console.log(data); //觸發用戶端事件c_hi socket.emit('c_hi','hello too!') }) //斷開事件 socket.on('disconnect', function(data) { console.log('斷開',data) socket.emit('c_leave','離開'); //socket.broadcast用於向整個網路廣播(除自己之外) //socket.broadcast.emit('c_leave','某某人離開了') })});
socket.on(EventName,function(date){})socket.emit(EventName,msg)這個後端示範了,前端發送訊息給後端，觸發hi事件，hi事件通過回調在觸發用戶端定義的c_hi事件告知前端。
用戶端
index.html
<!DOCTYPE html><html><head> <title>socket</title></head><body><button id="sendBtn">發送訊息</button><button id="leaveBtn">離開</button></body><script type="text/javascript" src="./socket.io.js"></script><script type="text/javascript"> var socket=io.connect('localhost:80'),//與伺服器進行串連 send=document.getElementById('sendBtn'), leave=document.getElementById('leaveBtn'); send.onclick=function(){ socket.emit('hi', 'hello!'); } leave.onclick=function(){ window.location.href="about:blank" rel="external nofollow" ; window.close() socket.emit('leave', 'leave'); } //接收來自服務端的資訊事件c_hi socket.on('c_hi',function(msg){ alert(msg) }) // socket.on('c_leave',function(msg){ // alert(msg) // })</script></html>
