  • 结合redis限制接口访问次数

        接了一个需求,公司有要调用一个其他平台的收费接口,调用一次,收取一次费用;需要封装一下,防止被恶意盗刷;自己思考了一下,,记录每个用户的访问次数,调用一次,累计数量+1,当达到设置上限 是,直接返回提示信息;;

        初步构思,从2个维度限制;1、限制每个用户每小时内的最大访问次数,,2限制每个用户每天的最大访问次数;;结合redis的 incrby 和TTL实现,,redis自增方法保证并发情况下 +1 操作线程安全; redis的 key  为  接口名+用户唯一标识+固定字符串(日期),value为访问次数,,并设置过期时间为  1小时,,一天; 代码如下:
