NodeJS 中的 Socket IO 连接问题

Question

我正在尝试在 NodeJS 应用程序中建立套接字连接。 我试图运行这段代码

index.js

---

const io = require('socket.io')(8000)

const users = {};

io.on('connection', socket =>{

    socket.on('new-user-joined', name =>{ 

        users[socket.id] = name;

        socket.broadcast.emit('user-joined', name);
    });

    
    socket.on('send', message =>{
        socket.broadcast.emit('receive', {message: message, name: users[socket.id]})
    });

 
    socket.on('disconnect', message =>{
        socket.broadcast.emit('left', users[socket.id]);
        delete users[socket.id];
    });
});

client.js

const user = prompt("Enter your name to join");
socket.emit('new-user-joined', user)

socket.on('user-joined', user =>{
    append(`${user} joined the chat`, 'right')
})

socket.on('receive', data =>{
    append(`${data.name}: ${data.message}`, 'left')
})

socket.on('left', user =>{
    append(`${user} left the chat`, 'right')
})

但我没有得到正确的结果和控制台中的任何错误。

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

var socket = io();


const user = prompt("Enter your name to join");
socket.emit('new-user-joined', user)

socket.on('user-joined', user =>{
    append(`${user} joined the chat`, 'right')
})

socket.on('receive', data =>{
    append(`${data.name}: ${data.message}`, 'left')
})

socket.on('left', user =>{
    append(`${user} left the chat`, 'right')
})

请在 HTML 中获取套接字连接。

请简要说明您遇到的问题。 谢谢。
