先說下業務規則 首次簽到可獲得獎勵 以及連續2天簽到可獲得獎勵
因為使用的是openid 而非使用者的uid
因此 此處的設計的key 為 openid 而判斷使用者是否簽到 的偏移量 為以某個起始時間 未開始的便宜來那個計算
另外還有一種方案是 以當天的日期為key 而偏移量 則為使用者的 uid (此處不採用的原因為 我們的業務uid 總量不算大 但是 間隔比較大 可能造成很大的 0 間隔)
redis 事件記錄 RedisManager
獲取 單例 getRedisConn
簽到 setSignUser($openid)
判斷今天簽到 getTodaySign($openid)
判斷某天簽到 getThisDaySign($openid,$date)
計算總的簽到數 countAllSignDay($openid)
計算連續簽到數 countContinueSignDay($openid)
計算還差幾次簽到可抽獎 getAwardNeedDays($openid)
鑑定今天是否能抽獎 decide_award($openid)
