How to destroy an angular factory instance

问题:

On the one hand, I have several factories where each factory controls a websocket.

On the other hand, One of those factories should be started when client is logged, so:

if(user.isLogged()){  $injector.get('NotificationsWebsocket') } 

That's the way I initialize my factory dinamically, the problem come up when the user logs out.

I don't know how to delete an instance of angular instances factory or how to destroy the NotificationsWebsocket. I tried to close socket, but when I log in again, the socket doesn't connect because factory is not reinstanciated.

回答1:

You cannot destroy factories, they are singletons and they are created only once when they are first required by a module.

You can add to your factory two methods: setup(), close() which will create and close socket.

When user logins you call setup(), when logging out - close().
