webSocketServer node.js如何区分客户端

您可以简单地将用户ID分配给数组CLIENTS []，其中将包含所有用户。您可以直接向所有用户发送消息，如下所示：

var WebSocketServer = require('ws').Server,    wss = new WebSocketServer({port: 8080}),    CLIENTS=[];wss.on('connection', function(ws) {    CLIENTS.push(ws);    ws.on('message', function(message) {        console.log('received: %s', message);        sendAll(message);    });    ws.send("NEW USER JOINED");});function sendAll (message) {    for (var i=0; i<CLIENTS.length; i++) {        CLIENTS[i].send("Message: " + message);    }}
