if it is only implemented in the foreground, you can only use a timer and keep requesting, which consumes too much memory
Real-time updates are basically based on socket protocol. You can take a look at
. message should be recorded in the database. When you read the message, you should send a ajax request to mark the message as read, and then use ajax to get the status of the message. Several messages are unread and then displayed.
to display the real-time data of unread messages, you can use websocket . When the message is received by the background, it is pushed over, and then update state is fine.
therefore, ajax request is used when actively manipulating data, and websocket
you can use the setstate method. This will be updated in time
