        logger.warning(f"发现 {len(orphan_tags)} 个孤儿标签")
    if duplicates:
        logger.warning(f"发现重复标签: {set(duplicates)}")
    # 清理过期标签（7天前标记为删除的）
    cleanup_time = datetime.datetime.now() - datetime.timedelta(days=7)
    for tag in manager.tags['tags']:
        if tag.get('status') == 'deleted' and tag.get('deleted_at'):
            if tag['deleted_at'] < cleanup_time.isoformat():
                manager.tags['tags'].remove(tag)
    manager._save_tags()
# 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

1. 版本控制：每次更新都记录变更历史
2. 增量更新：支持部分更新而非全量替换
3. 权限控制：记录修改人信息
4. 原子操作：确保批量操作的原子性
5. 备份恢复：定期备份，支持回滚
6. 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。
