"""
QQ 号/群号 ↔ 用户名/群名 转换脚本

将数字 ID 转为可读的名称。通过 NapCat (OneBot) HTTP API 查询。

用法:
  # 解析单个 QQ 号
  python3 qq_resolve_name.py --uid YOUR_ADMIN_QQ
  python3 qq_resolve_name.py --uid YOUR_ADMIN_QQ --json

  # 解析单个群号
  python3 qq_resolve_name.py --gid YOUR_GROUP_ID
  python3 qq_resolve_name.py --gid YOUR_GROUP_ID --json

  # 批量解析
  python3 qq_resolve_name.py --uid YOUR_ADMIN_QQ --uid 12345678 --gid YOUR_GROUP_ID
  python3 qq_resolve_name.py --uid YOUR_ADMIN_QQ --gid YOUR_GROUP_ID --json

  # 从文件读取待解析的 ID（每行一个：uid:123456 或 gid:YOUR_GROUP_ID）
  python3 qq_resolve_name.py --from-file /tmp/ids.txt
  python3 qq_resolve_name.py --from-file /tmp/ids.txt --json
