服务端代码/***/

// 服务端代码
var express = require('express');
var app = express();
var path = require('path');
var server = require('http').createServer(app);
var io = require('socket.io')(server);
var port = process.env.PORT || 5000;

server.listen(port, () => {
  console.log('Server listening a1111 port %d', port);
});

io.on('connection', (socket) => {
  socket.on('add user', (username) => {
    	console.log(username)
  });
});

  客户端代码/****/使用socket.io/2.2.0

var socket = io();
    socket.on('login', (data) => {
        console.log('login')
        socket.emit('add user', {1:2});
    });

    socket.on('disconnect', (data) => {
        console.log('disconnect')
        socket.emit('add user', {1:2})
    });

    socket.on('connect', (data  ) => {
        console.log('connect')
        socket.emit('add user', {1:2})
    });

  配上nginx的配置

location /socket {
            #此处改为 socket.io 后端的 ip 和端口即可
            proxy_pass http://xxx.xxx.xx.xx:5000;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_http_version 1.1;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
}
