First of all, business rules can be rewarded for first signing in and for two consecutive days can be rewarded for signing in.
Because openid is used instead of user's uid
So the key designed here is openid and the offset to determine whether the user checks in or not is calculated at a cheaper price that does not start at a certain starting time.
Another solution is to use the date of the day as the key and the offset as the user's uid.
redis event record RedisManager
Get the singleton getRedisConn
Check in setSignUser ($openid)
Judge today to check in getTodaySign ($openid)
Check in getThisDaySign ($openid,$date)
Calculate the total number of check-ins countAllSignDay ($openid)
Calculate countContinueSignDay ($openid)
It's a few times short of checking in getAward NeedDays ($openid)
Identify if today's lottery decision_award ($openid)
