提供客户端IP获取和地理位置查询:
|
提供客户端IP获取功能:
|
||||||
- get_client_ip: 获取客户端真实IP(需配合Flask ProxyFix使用)
|
- get_client_ip: 获取客户端真实IP(支持反向代理场景)
|
||||||
- get_ip_location: 调用第三方API查询IP地理位置
|
|
||||||
|
地理位置查询请使用 ip2region 模块(离线数据库,高性能)。

优先级:

request.remote_addr为真实客户端IP。未配置ProxyFix时,

1. X-Forwarded-For 头(反向代理场景,取第一个非内网IP)

request.remote_addr即为直连IP,避免客户端伪造。
