在geolite2 .mmdb文件(JAVA)上按城市名称查询 [英] Query by city name on geolite2 .mmdb file (JAVA)

问题描述

我正在使用GeoLite2通过IP地址获取Java应用程序的位置.

I am using GeoLite2 to get Location by IP address for my java appliccation.

我想从GeoLite2-City.mmdb文件中按城市获取国家/地区.

I want to get country by city from GeoLite2-City.mmdb file.

这是我的读者:

DatabaseReader reader = new DatabaseReader.Builder(dbFileStream).withCache(new CHMCache()).build();

我正在通过IP地址获得CityResponse，如下所示:

I am getting CityResponse by IP address like below :

 CityResponse cityResponse = reader.city(InetAddress.getByName("an IP address"));

但是我想按城市获取国家名称:

But I want to get Country name by city like this :

String countryName = reader.getCountryByCity("Paris");

有什么办法可以做到这一点?

Is there any way to do this ?

推荐答案

这是不可能的.该数据库旨在通过IP地址进行查找.如果您需要通过其他方式访问数据，我建议使用MaxMind提供的CSV文件.

This isn't possible. The database is designed to do lookups by IP address. I would suggest using the CSV files that MaxMind provides if you need to access the data in some other way.

此外，您可以尝试项目 geonames.org 和

Also, you can try project geonames.org and their java-api library
