1、首先安裝好nodejs-websocket
npm install nodejs-websocket --save -g
2、編寫服務端
var ws = require("nodejs-websocket")var AllUserData = new Array()// Scream server example: "hi" -> "HI!!!"var server = ws.createServer(function (conn) { console.log("New connection") conn.on("text", function (str) { console.log("Received "+str) AllUserData.push({ 'id':str, 'ws':conn }) conn.sendText(str.toUpperCase()+"!!!") }) conn.on("close", function (code, reason) { console.log("Connection closed") // 當用戶退出的時候捕捉到退出的用戶 for (var i=0 in AllUserData) { if (AllUserData[i].ws == conn) { console.log(AllUserData[i]) } } })}).listen(8001)3、簡易客戶端
<!DOCTYPE html><html><head> <title>django-websocket</title> <script src="http://code.jquery.com/jquery-1.11.1.min.js"></script> <script type="text/javascript">//<![CDATA[ $(function () { $('#connect_websocket').click(function () { if (window.s) { window.s.close() } /*創建socket連接*/ var socket = new WebSocket("ws://127.0.0.1:8001"); socket.onopen = function () { console.log('WebSocket open');//成功連接上Websocket }; socket.onmessage = function (e) { console.log('message: ' + e.data);//打印出服務端返回過來的數據 $('#messagecontainer').prepend('<p>' + e.data + '</p>'); }; // Call onopen directly if socket is already open if (socket.readyState == WebSocket.OPEN) socket.onopen(); window.s = socket; }); $('#send_message').click(function () { //如果未連接到websocket if (!window.s) { alert("websocket未連接."); } else { window.s.send($('#message').val());//通過websocket發送數據 } }); $('#close_websocket').click(function () { if (window.s) { window.s.close();//關閉websocket console.log('websocket已關閉'); } }); }); //]]></script></head><body><br><input type="text" id="message" value="user1"/><button type="button" id="connect_websocket">連接 websocket</button><button type="button" id="send_message">發送 message</button><button type="button" id="close_websocket">關閉 websocket</button><h1>Received Messages</h1><div id="messagecontainer"></div></body></html>總結
以上所述是小編給大家介紹的nodejs 使用nodejs-websocket模塊實現點對點實時通訊，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對VeVb武林網網站的支持！
