Passing data from upgrade to websocket

[streamich]

I'm trying to pass headers from the upgrade callback to the WebSocket object, so that I can access those headers on websocket "open" and "message" callbacks.

For example, let's say I want to access a header called Super-Header in "message" callback, I'm looking for something like this:

  {
      upgrade: (res, req, context) => {
        context.mySuperHeader = req.getHeader('super-header');

        res.upgrade({
          url: req.getUrl()
          },
          req.getHeader('sec-websocket-key'),
          req.getHeader('sec-websocket-protocol'),
          req.getHeader('sec-websocket-extensions'),
          context);
      },

      message: (ws, message, isBinary) => {
        ws.context.mySuperHeader // <---------------------------
      },
  }

I'm sorry if it is a stupid questions, I just cannot find a documented way to do it.

I see in C++ version there is req param in open callback.

If something like that was in Node version that would solve it, but I cannot find one.

Unfortunately I'm not a C++ developer, but maybe something like this could be a patch?

In addition to having req in open, would still be nice to have a way to pass data from upgrade to open.

nvm, found the right way of doing it: #339 (comment)
