When I connect to a website who uses websockets, I can get the frames with the Google Developer Tools.

Data from the websocket url

So I would like to get the same data but in a program ( JS, C# ) but I actually have no idea how I should do.

I thought about make a http.request with NodeJS but it's not a http url :/ I thought about make a sample JS client but I couldn't get the data because I wasn't able to send the headers with the 'key'.

The headers

So, I really hope you have a way to help me and sorry for my basic English :(

• You can use libraries like socket.io to connect with the ws:// and wss:// protocols. – wrxsti Commented Mar 31, 2016 at 18:33
• A quick google came up with npmjs./package/websocket for node. and msdn.microsoft./en-us/library/… for – phuzi Commented Mar 31, 2016 at 18:36

WebSockets is a standard technology to implement stateful, persistent connections between clients and servers. It has its own protocol ws:// and wss:// (like https://).

What you need is a proper WebSocket client to receive data from the server.

The problem here is WebSockets it's not a protocol per se. There's no concept of request and response. It's like working with TCP sockets.

If you want to work with WebSockets, NodeJS has Socket.IO client API.

In C#, you should take a look at SignalR.
