- git 初始化 + .gitignore 补全(根 .env / logs / instance / __pycache__ 等) - 修复 utils/.gitignore 误将整个 utils/ 源码层忽略的问题,补入全部工具源码(含 ip2region.xdb) - 含后端全部代码:application / extensions / utils / config / migrations - 含前端 ui/(后续整体迁走) - 不含根 .env(含密钥,本地保留) Co-Authored-By: Claude <noreply@anthropic.com>

IP地理位置查询模块(基于ip2region离线数据库)
|
|
=============================================================
|
|
|
|
基于 ip2region.xdb 离线数据库提供高性能IP地理位置查询,无需网络请求。
|
|
|
|
核心功能:
|
|
- get_ip_region: 根据IP获取完整区域信息字典
|
|
- get_ip_location: 根据IP获取地理位置文本(兼容现有调用)
|
|
- get_ip_country / get_ip_province / get_ip_city / get_ip_isp: 按层级获取
|
|
|
|
xdb文件位于 utils/ip2region.xdb,启动时全量加载到内存,查询零IO延迟。
