HTML5 WebSocket的应用场景

HTML5 WebSocket的实现

var webSocket = new WebSocket('ws://localhost:8080');
webSocket.onopen = function(event) {
    console.log('WebSocket已经打开');
};
webSocket.onmessage = function(event) {
    console.log('收到消息：' + event.data);
};
webSocket.onclose = function(event) {
    console.log('WebSocket已经关闭');
};
webSocket.onerror = function(event) {
    console.log('WebSocket发生错误');
};

const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });

wss.on('connection', function connection(ws) {
    console.log('WebSocket已经连接');
    ws.send('欢迎使用WebSocket');
    ws.on('message', function incoming(message) {
        console.log('收到消息：', message);
        ws.send('收到消息：' + message);
    });
    ws.on('close', function close() {
        console.log('WebSocket已经关闭');
    });
});
