Zincrby key increment member

Note: when executing the zincrby command, if the current key does not exist, it is equivalent to executing the zadd command.

two。 The user is disliked.

There can be two situations:

When the user cancels giving likes, we can still use the zincrby command mentioned on the computer, but write the increment parameter as a negative number.
