Question

在 HTML 中我有这个：

<script src="https://cdn.socket.io/3.1.2/socket.io.js"></script>

还有：

var socket = io.connect('http://www.myurl.com:8000');

如果我运行它，我会收到错误“连接被拒绝”。我目前有这个 index.js：

var express = require('express')
  , http = require('http');
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);

app.get('/', (req, res) => {
  res.sendFile(__dirname + '/index.html');
});

io.on('connection', (socket) => {
  socket.on('chat message', (msg) => {
    io.emit('chat message', msg);
  });
});


server.listen(8000);

我相信

var io = require('socket.io').listen(server);

必须

var io = require('socket.io')(server);

见https://socket.io/docs/v3/server-initialization/#With-Express。

socket.io 连接被 node.js 拒绝
