获取钉钉考勤机的打卡记录并且解析

有个特别恶心的地方就是打卡信息只能最多一次取七天的。所以要注意一下；  时间格式：2018-05-01

钉钉突然改接口了，直接获取是被拒绝了，加了分页限制，加了人数限制，头大，之前得方法不能用了，重新写了版，最多一次获取50个人的考勤，并且这些人的考勤记录一次只能获取50条，我想了个办法中心思想就是首先拆分公司人员的dingId的列表，拆成每50个一组，然后限制分页最大50个每页，50个人的打卡记录肯定大于最大限制，每次获取返回的考勤记录判断它给返回的hasMore是不是true是的话还将这50个人作为条件，偏移量加50，查询下一部分的考勤记录，如果是false则说明已经获取这50个人的全部数据，那么则将之后的50个人作为新的条件，继续以上判断，如果大家有更好的方法欢迎来留言，学习一下。环境是jdk 1.8,maven 3.5.4,tomcat 7.0.8
