As of Socket.io version 1, resource has been replaced by path. Use :

<pre><code>var socket = io('http://localhost', {path: '/nodejs/socket.io'});

If you are using express with nodejs:

Server side:

<pre><code>var io = require('socket.io')(server, {path: '/octagon/socket.io'});
</code></pre>

then

<pre><code>io.on('connection', function(socket) {
 console.log('a user connected, id ' + socket.id);
 socket.on('disconnect', function() {
 console.log('a user disconnected, id ' + socket.id);
 })
})
socket.on('publish message ' + clientId, function(msg) {
 console.log('got message')
 })
</code></pre>

Client side:

<pre><code>var socket = io('https://dev.octagon.com:8443', {path: '/octagon/socket.io'})
</code></pre>

then

<pre><code>socket.emit('publish message ' + clientId, msg)

blocks|key|1028871|text|为实现这一目标，我采用了以下方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1028872|客户端：|1028873|var+socket+=+io.connect('http://localhost:8183/?clientId='%2BclientId,{"force+new+connection":true});|code-block|syntax|javascript|1028874|服务器端：|1028875|var+io+=+require('socket.io').listen(server);

server side:

<pre><code>var io = require('socket.io').listen(server);
io.sockets.on('connection', function(socket) {
 console.log("url"+socket.handshake.url);
 clientId=socket.handshake.query.clientId;
 console.log("connected clientId:"+clientId);

});

blocks|key|1028967|text|如果你正在用快递服务你的应用程序，那么也许你可以看看这个。记住，express使用http为您的应用程序提供服务。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1028968|const+express+++=+require('express'),

If you are serving your app with express, then maybe you can check this out. Remember express uses http to serve your application.

<pre><code>const express = require('express'),
 http = require('http'),
 socketIo = require('socket.io'),
 app = express()

var server = http.createServer(app);
var io = socketIo(server);

io.on('connection', (socket)=&gt;{
 // run your code here
})

server.listen(process.env.PORT, ()=&gt; {
 console.log('chat-app inintated succesfully')
})
</code></pre>

I have the current setup: 

<ol>
<li>Nodejs Proxy (running http-reverse-proxy) running on port 80. </li>
<li>Rails server running on port 3000 </li>
<li>Nodejs web server running on port 8888</li>
</ol>

So any request starting with /nodejs/ will be redirected to nodejs web server on 8888. 

Anything else will be redirected to the rails server on port 3000. 

Currently Socket.io requires a connection url for io.connect. 

Note that /nodejs/socket.io/socket.io.js is valid and returns the required socket.io client js library. 

<hr>

However, I am not able to specify connection_url to /nodejs/ on my server. 

I have tried <a href="http://myapp.com/nodejs">http://myapp.com/nodejs</a> and other variants but I am still getting a 404 error with the following url <a href="http://myapp/socket.io/1/?t=1331851089106">http://myapp/socket.io/1/?t=1331851089106</a> 

<h2>Is it possible to tell io.connect to prefix each connection url with /nodejs/ ?</h2>

Socket.io connection url?

我有当前的设置：运行在端口80上的Nodejs代理(运行http-反向代理)。Rails服务器运行在端口3000 Nodejs web服务器上，运行在端口8888上因此，任何以/ nodejs /开头的请求都将被重定向到8888上的nodejs web服务器。其他任何内容都将重定向到端口3000上的rails服务器。目前，Socket.io需要io.connect的连接url。注意，/nodejs
