Query the read message ID

GET
https://192.168.88.11:9781/bvcsp/v1/im/msg/mark
Last modified:2025-02-26 09:23:29
Get the message ID of messages that I have read.
Rule: After msgid is marked as read, all messages less than or equal to msgid are read messages. Messages greater than this message ID are unread messages.
Don't mark them as read frequently (after receiving each message), you can mark the largest message ID received in a period of time (10 seconds) as read.
