How to receive NodeBB server notification from external web socket client

learner

I have installed NodeBB for exploring it's features and it is superb one. I am trying to receive notifications that are received and displayed on NodeBB page (local installation) in an external web socket client that I have developed. My NodeBB server is running at http://localhost:4567 and I tried to use the same URL in my websocket client app to connect and receive notifications from my NodeBB server. However, it didn't work.
I have developed a simple Node express server that runs on http://localhost:8080 and I can receive notifications from that server in my web socket client using the URL http://localhost:8080.
If someone can provide pointers / help on how can I connect my web socket client to my local NodeBB server and receive notifications that will be very helpful.

Thanks in advance!

Make sure you're using socket.io for all websocket stuff.

There's probably some configuration with regard to socket.io that has to be made.

That's all I've got.

Thanks for the reply. I am trying to build my web-socket client as windows application. I am not using nodeJS for this.

@learner What language are you using?

I am using C#

Are you connecting to /socket.io?

@julian Thanks for response and sorry for delay on my part as I was down!

I notice that while connecting to the websocket, browser requests with URL like below -

ws://<IP address>:4567/socket.io/1/websocket/GQlkcIbCyFu8a5C_tNyL

The last portion of the URL, i.e, “GQlkcIbCyFu8a5C_tNyL” changes to some different value in times and is not static throughout the browser session.

If I try to connect to the socket without this token, i.e, “ws://<IP address>:4567/socket.io/1/websocket”, I am not able to connect to it. It requires the last part as well. I am not sure how this token is generated or how to fetch this token before starting the socket connection.

If I try chrome websocket plugin to test connection, I always get handshake error “7:::1+0” if I do not use this token, otherwise able to connect to it with token copy pasted from browser dev eloper tools.

Thanks for your guidance in advance!

I'm unfamiliar with C#, and we don't handle socket establishing on our end, we just let the socket.io library handle it.

Perhaps you can get a better idea by investigating the source code of this project? http://socketio4net.codeplex.com/

Hi Julian,
I am using that only. Can you provide some help on how can I connect using Chrome Web socket plugin, I mean what URL to use? That might clarify my query.

My objective of using C# is that I want to see whether I can get notifications from outside without logging into my local NodeBB application.

Thanks!
