I dont want that, I would like to use a middleware solution that automatically checks a token and allows or not to continue.ġ Is it possible to use a token-based, middleware-based solution in ws?Ģ How to set a header with a token in a ws connection?ġ) In my experience there is no available express.js middleware and the solution i found requires to listen to the upgrade event on your http server and blocking access to your socket connection before it reaches ws routes.Ģ) Your browser will not allow setting additional headers during websocket connection on the client side. But to check it, I have to allow the connection first. The WebSocket protocol has only two agendas: To open up a handshake and to help the data transfer. ![]() Just send const socket = new WebSocket(currentUrl) with some data and include a valid token in that data. The WebSocket protocol offers persistent, real-time, full-duplex communication between the client and the server over a single TCP socket connection. I dont get any errors, but I dont know how to get the Authorization "header" in node This errors Failed to construct 'WebSocket': The subprotocol '' is invalidĬonst socket = new WebSocket('ws://localhost:5001/user/Nick/25', ) In that route, I would like to use the token.validate() middleware -that in HTTP connections, checks the Authorization header ('/user/:name/:id', token.validate(), (ws, req) => // websocket headers to be used e.g. ![]() My ws server const wsHttpServer = http.createServer() Īpp.use('/ws', require('./routes/wsroute')) So, I can reuse the token-middleware solution that I have in my HTTP connections. Since my ws server is based on an HTTP one const wsHttpServer = http.createServer() Ĭonst expressWs = require('express-ws')(app, wsHttpServer) Īnd since the ws connection is based on an HTTP one that gets upgraded to a ws, WHY I cannot pass a token in my ws that the express route checks, like any other one? My logic is, send the token, check it, if it is ok, proceed to upgrade to a ws connection. I am looking for a solution to authenticate users in websocket connections, based on a token. I use node.js, express and express-ws that is based on wsĮxpress-ws allows to create express-like endpoints for websockets. ![]()
