WebSocket allows the server to actively push data to the client.
In the WebSocket API, the client and the server only need to complete a handshake once, and a persistent connection can be created directly between the two, and two-way data transmission can be performed.
WebSocket is mainly used to refresh the token, the user is kicked out, the platform message, the memory and CPU display, the current system online number in the platform log, and the determination of the editing status of the data connection.
FineBI project is configured with WebSocket port and WebSocket forwarding port by default.
According to different engineering environments, the effective order of the two ports is not exactly the same. According to the effective order, it will try to listen in turn. If one port is successfully monitored, other ports will not be tried.
