# 每天凌晨2点执行
schedule.every().day.at("02:00").do(check_tag_health)
while True:
schedule.run_pending()
time.sleep(60)
使用示例
# 添加标签 python tag_cli.py add --name "机器学习" --category "技术" --desc "ML相关标签" # 更新标签 python tag_cli.py update --name "机器学习" --desc "更新描述" # 批量导入 python tag_cli.py import --file new_tags.json # 导出所有标签 python tag_cli.py export --file backup.json # 列出所有标签 python tag_cli.py list
最佳实践建议
- 版本控制：每次更新都记录变更历史
- 增量更新：支持部分更新而非全量替换
- 权限控制：记录修改人信息
- 原子操作：确保批量操作的原子性
- 备份恢复：定期备份，支持回滚
- 监控告警：发现异常变更及时告警
这个标签体系维护脚本可以根据实际业务需求进行扩展,比如支持标签层级关系、标签权重、自动关联等高级功能。
