我尝试了许多方法来用Express连接套接字-io客户端和服务器，但是它不起作用，现在我不知道可能是什么错误。

我试图克隆socket-io网站上可用的示例，但它没有显示任何连接或没有执行任何功能。

This is server.js and this is my code i have made many changes in it but not working.


var express = require('express');
var app = express();
var path = require('path');
//require socket.io
var http = require('http').createServer(app);
var io = require('socket.io')(http);

//Setup a public path to load files
app.use(express.static('public'))
//app.use(express.static(path.join(__dirname,'public')));

//Route for index
app.get(('/'),(req,res)=>{
    res.send('index'); 
});

//Socket connection

io.on('connection',function (socket) {
    socket.emit('news',{ hello: 'world' });
    socket.on('my other event',function (data) {
      console.log(data);
    });
  });



app.listen(3000,()=>{
    console.log('server running on port 3000');}
);


This is index.html that the server.js is sending i only included the script 


    <script src="/socket.io/socket.io.js"></script>

   <script>
      var socket = io.connect('http://localhost:3000');
      socket.on('news',function (data) {
        console.log(data);
        socket.emit('my other event',{ my: 'data' });
      });
    </script>

I expect it to console log when socket is connected and disconnected and emit the functions normally.
