NOTE: Spring Security requires authentication performed in the web application to hand off the principal to the WebSocket during the connection. The WebSocket server can use any client authentication mechanism available to a generic HTTP server, such as cookies, HTTP authentication, or TLS authentication. Practically, this means that a WebSocket opened from a page behind auth doesn’t "automatically" receive any sort of auth. None of these three mechanisms works well in practice. com does not have login form, user enter to acme. If your session cookie changes during a session (ex: due to session ID rotation), your client has to Using a JWT to authenticate a websocket connection As long as you don't use long-live tokens or even infinite valid tokens (expiration time) I would say it's a solid solution. I use node. I am using ClientWebSocket to connect to the Zendesk chat streaming API using an OAuth token like this: var webSocket = new ClientWebSocket(); webSocket. Instead, I'll be using dummy values with a lose approach to authenticate users. SetRequestHeader("Authorization", $"Bearer {_oauthToken}"); var cts = new CancellationTokenSource(); await webSocket. io connection? My application uses a login endpoint from another server (python) to get a token, How to pass a message while connecting to websocket server on node. The next example uses server-side configuration to register a custom authentication interceptor. The WebSocket spec has been is constant flux. Normally JWT is used in a REST API environment, so the user first authorizes using an authentication endpoint, with username and password for example, and then gets handed out a valid JWT. So you can perform authentication in the web server, return an authentication cookie, and then the websocket will send that cookie to the server again.
