How do I choose between handlerAdded and channelActive when the web client reaches my websocket server?

Question

My program has a websocket server. The server connects the client connection in two ways: "handlerAdded" and "channelActive". What should I use when the web client arrives?

Answer 1

ChannelActiverecommended, while in the server context handlerAddedthey ChannelActiveare called one after another, when you transfer the handler to the client side, it handlerAddedis called before the call ChannelActive, which makes your code an error, since the record does not work until the channel is active.

Q handlerAdded: channel().isActive() there is either true or false

ChannelActive: channel().isActive() ^*

, channel().isActive() .
