IDM 用户帐号过期提醒

2024-01-02 10:18:48

芯片设计环境通常有比较严格的安全管理,用户帐号过期后就不能登录环境,影响用户工作。为减少影响,应该提前向用户发送提醒,及时更新密码。

方案设计

通过IDM REST API接口获取所有帐号信息,根据以下条件过滤,筛选出即将过期帐号和已过期帐号。

  1. 帐号类型为正式员工(employee)和实习生(intern)

  2. 帐号没有在需要忽略的清单中

  3. 帐号过期日期相对于今天的间隔时间在指定间隔时间内

筛选出需要通知的帐号列表以后,遍历列表,如果帐号与公司人事系统不一致,使用公司人事系统帐号,最后记录日志并发送飞书提醒给用户。

飞书通知示例如下:

通过设置配置文件中的参数 NOTICE_DATES 控制发送通知的频率,下面的配置为提前15、7、4、2、1天和当天,以及过期后1、2、4、7、14、21天后发送通知。

NOTICE_DATES: [15, 7, 4, 2, 1, 0, -1, -2, -4, -7, -14, -21, -28, -35, -42, -49, -56, -63, -70, -90, -120, -150, -180, -210]

可能通过 crontab 或 Jenkins 每天运行一次即可。?
