什么是Api接口幂等？
【篡改常识的系统最新章节网站防篡改设备】大略来说Api接口幂等在有限的功夫内控制接口考察乞求，控制ip考察度数，不控制平台考察，都不妨拿到数据 。一个接口不不妨反复表单提交，消费一次耗费一次 。
用户场景：同一功夫反复提交屡次乞求 。
什么是数据窜改？
api接口数据窜改，剧本文献，窜改接口参数举行效劳器数据夺取，重要的数据窜改会引导数据库宕机，步调软硬件解体 。
想到这边都领会后盾api接口幂等多要害了吧 。即日给大师讲非对称加密实行后盾接口api幂等 。
实行思绪：jtw+ 考证标识+出面密钥+暂时功夫戳+寄存过时功夫+AES 实行加密算法token 。
实行办法：1，用户登录胜利后，消费加密token寄存redis.
2,下次登录检查token 能否过时，过时请从新登录 。
3，用户登录生存灵验期，不须要登录 。（这边即是单点登录办法）
code中心实行类：
