websocket is used in the project to obtain information and update, but once the websocket link is broken, the information sent by the server cannot be received. Even if the connection is reconnected, the back end of the information during the previous disconnection does not seem to be retransmitted, resulting in the status cannot be updated. Is there any specific solution to retrieve the information and data during the disconnection period?
