How to properly pull the observer from another method?

Question

Angular

Roughly speaking, there is a login method that sends a command to the websocket, after the response in onMessage, the Observable needs to work. i.e. subscribe worked or error.

I really don’t want to use EventEmitter, but as I understand it, it’s not entirely correct to take out observers

Answer 1

You show the code, it is not entirely clear what you are going to pull and why.

Answer 2

You don’t need to pull the observer, you need to emit the value in the observable, and the observer must be subscribed to it
