req removed from ws open handler

[acharkov]

I used req from open handler to get the real client address in case of proxy.
My old code was like this (at least in version 17.4.0)

open: (wsConn, req) => {
   ...
   this.ip = req.getHeader('cf-connecting-ip') || remoteAddressToString(conn.getRemoteAddress())
}

but in latest version open handler is changed - req removed. How I could get proxied ip for websocket connection in this case?

v18 removes req from the ws open handler - v18.0.0
docs - WebSocketBehavior.html#upgrade
docs - HttpResponse.html#upgrade
examples - Upgrade.js - UpgradeAsync.js

you need to use the ws upgrade handler to pass values from the original http request:

// pass values from ws upgrade handler

uws.App().ws('/', {
   upgrade: (res, req, context) => { // request was made to open websocket, res req have all properties for request, cookies etc
      // add code here to determine if ws request should be accepted or denied
      // deny request with "res.writeStatus('401').end()" see issue #367
      res.upgrade( // upgrade to websocket
         { ip: res.getRemoteAddressAsText() }, // 1st argument sets which properties to pass to ws object, in this case ip address
         req.getHeader('sec-websocket-key'),
         req.getHeader('sec-websocket-protocol'),
         req.getHeader('sec-websocket-extensions'), // 3 headers are used to setup websocket
         context // also used to setup websocket
      )
   },
   open: ws => {
      console.log(ws.ip)
   }
})
