Type 1: The system gives the user a certain reward. If the user does not receive it within 24 hours, the reward will be automatically revoked.

Second type: Automatically execute a method at 0 o'clock every day.

What methods are used to achieve these two methods?

The first one: Record the timestamp when the reward is issued, check the timestamp when the user (or others who need to call this reward) accesses, and mark it as revoked if the time is up if it is not claimed.
The second one: Use a server shell script , visit a fixed URL regularly, and the URL executes this method.

• When the system distributes rewards, you can set a 24-hour session with the user's ID. If it is not claimed for 24 hours, it will automatically expire. If it is claimed, the corresponding session will be deleted directly

• You can set a scheduled task to execute at 0 o'clock every day, just run it at midnight every day
