I tried to communicate with deno_std WebSocket Client and a WebSocket Endpoint of Chrome DevTools, but handshake was rejected by Chrome.
I had to add a
sec-websocket-versionfield to the request header to fix this.According to the RFC,
sec-websocket-versionis required for the WebSocket Client implementation.https://tools.ietf.org/html/rfc6455#page-60
