NodeJS多种创建WebSocket监听的方式(三种)

const net = require('net');
 
const server = net.createServer((socket)=>{
 socket.on("connect",(data)=>{
 console.log("connect");
 })
});
 
server.listen("8111","127.0.0.1")

const WebSocketServer = require("ws").Server;
var ws = new WebSocketServer({ host: webConfig.ip, port: webConfig.port })
 
io.on('connection', function (socket) {
 socket.on("close", function () {
 console.log("server close");
 });
 
 socket.on("error", function (err) {
 console.log("server error " + err);
 });
 
 socket.on("message", function (cmd, data) {
 console.log("server rcv data=" + cmd);
 socket.send(data);
 });
});

const io = require('socket.io')(webConfig.port);
io.sockets.on('connection', function (socket) {
 socket.on('getSysConf', function (data) {
 console.log("get sys config ");
 });
});
