Here is my code:
var socket = require('socket.io-client')('http://127.0.0.1:3000/printers', { query: "shop=" + "123456", transports: ["websocket"] }); If I delete query, I can connect to socket. Where am I wrong?

There doesn't seem to be anything wrong with your client-side code. I can connect by copying and pasting your code.
I suspect the problem is within your server-side code. Here is an example I am using with your client-side code:
var http = require('http'); var io = require('socket.io'); var server = http.createServer(function(req,res){ res.writeHead(200); res.end('Hello, World!\n'); }); server.listen(80); var socket = io.listen(server); socket.use(function(socket, next){ console.log("Query: ", socket.handshake.query); if (socket.handshake.query.shop == '123456') { next(); } next(new Error('You cannot use that shop')); }); socket.on('connection', function(client) { console.log('New Connection'); }); I'm able to obtain the query data in the 'socket.use' function. If I don't call the next() function, the client will never get the message that the server has received the response and is connected.
I recommend checking out the example used in this thread.

If this doesn't resolve your issue, can you please post a bit more of your code. 👍

I found that the problem is about latest version of Socket.IO Client. I downgraded to 1.4.7 version and it worked.
