node.js - Socket IO 连接到 ws ://someAddress was interrupted while the page was loading

Question

我正在尝试跟随一个位于 http://socket.io/get-started/chat/ 的 Socket.IO 的简单示例。 .到目前为止，我的 index.js 文件中有以下代码:

// INDEX.JS Filevar app = require('express')();var http = require('http').Server(app);var io = require('socket.io')(http);app.get('/', function (req, res) {    res.sendfile('index.html');});io.on('connection', function (socket) {    socket.on('chat message', function (msg) {        console.log('message: ' + msg);    });});http.listen(3000, function () {    console.log('listening on *:3000');});

我得到的错误是:

The connection to ws://localhost:3000/socket.io/?EIO=2&transport=websocket&sid=i0SyiRvHJC1GUiafAAAC was interrupted while the page was loading.

我正在使用 FireFox 浏览页面。它在 Chrome 中也不起作用。

Answer 1

完全以您的示例为准，对我来说效果很好。我确实收到一个错误，但与您指示的不一样(这很好，因为这里不存在此 session ):

{
  code: 1,
  message: "Session ID unknown"
}

index.html 是否在正确的路径中(您的应用可见)？
