Flutter Support about beaver HOT 3 CLOSED

I am not an expert with flutter but from the error Connection to http[s]:// $$$$' was not upgraded to websocket, it seems your code still doing HTTP connection & need to upgrade to webSockets. I think it can be done by sending these headers

Connection: Upgrade
Upgrade: websocket

As explained here https://developer.mozilla.org/en-US/docs/Web/HTTP/Protocol_upgrade_mechanism#Upgrading_to_a_WebSocket_connection

I checked this website wss://echo.websocket.org/ and i see these header in the request & server response so maybe we have to add these headers in beaver response if sending the headers solely won't help. so pls let me know!

from beaver.

IOWebSocketChannel.connect('wss://go-beaver-k8s-1.nimi24.com/',
headers: {
'token': '',
'Connection': 'Upgrade',
'Upgrade': 'websocket',
}),
the same issue
I/flutter ( 3355): AsyncSnapshot(ConnectionState.done, null, WebSocketChannelException: WebSocketChannelException: WebSocketException: Connection to 'https://go-beaver-k8s-1.nimi24.com:0/#' was not upgraded to websocket)

from beaver.

Well that's interesting because beaver already add these headers https://github.com/gorilla/websocket/blob/c3dd95aea9779669bb3daafbd84ee0530c8ce1c1/server.go#L217

I just tested that.

What is the URL y use to connect as a client, it should be something like
wss://go-beaver-k8s-1.nimi24.com/ws/$$CLIENT_ID$$/$$CLIENT_TOKEN$$

so i assume you use IOWebSocketChannel.connect('wss://go-beaver-k8s-1.nimi24.com/ws/~client-id~/~client-token~',?
token not need in headers actually

and to create a client id and token

$ curl -X POST \
    -H 'Content-Type: application/json' \
    -H 'X-AUTH-TOKEN: YOUR-API-TOKEN-HERE' \
    -d '{"channels": []}' \
    'https://go-beaver-k8s-1.nimi24.com/api/client'

{
  "channels": [],
  "created_at": 1609269864,
  "id": "0de46431-af57-4768-8d2d-14b8c07a1f0b",
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJkYXRhIjoiMGRlNDY0MzEtYWY1Ny00NzY4LThkMmQtMTRiOGMwN2ExZjBiQDE2MDkyNjk4NjQiLCJ0aW1lc3RhbXAiOjE2MDkyNjk4NjR9.1vNZ20Ehj-OeFDPIF21QN84a-mip4F5ZMTKLahvk1iw",
  "updated_at": 1609269864
}

I am trying to know if it is issue with flutter or not. so can you try to init a websocket from browser > inspect > Console, don't forget to replace client id and token.

function Socket(url){
    ws = new WebSocket(url);
    ws.onmessage = function(e) { console.log(e); };
    ws.onclose = function(){
        // Try to reconnect in 5 seconds
        setTimeout(function(){Socket(url)}, 5000);
    };
}

Socket('wss://go-beaver-k8s-1.nimi24.com/ws/~client-id~/~client-token~');

UPDATE: that didn't help, same issue on flutter repo https://github.com/flutter/flutter/issues?q=Connection+to+was+not+upgraded+to+websocket+
