Is there a way to send meta data when opening a WebSocket?

I'm looking for a way to send a unique identifier to the server when opening a WebSocket.

I could implement this by sending an handshake message after being connected, but it would be very nice if that wasn't needed and instead I could just send and read the identifier via meta data, similar to header fields in http requests.

The WebSocket connection is initiated via an HTTP GET request. So you can include meta-data in the GET headers, like you would for any other request. Alternatively, you can append some params in the query string of the ws endpoint: ws://site.com/stream?param=foo, and parse the data on the server-side (will be received as a GET request).
