java - 如何在java中根据IP地址获取城市名称？

Question

在java中是否可以根据IP地址知道城市名称？

Answer 1

您使用的是 jsp 还是什么？对于客户端的城市名称，您可以使用谷歌的 API，它将返回与 IP 映射的用户的地理详细信息。正如谷歌的文档所说，您可以获得以下内容

填充后，google.loader.ClientLocation 对象会填充以下都市级别的粒度属性:

* ClientLocation.latitude — supplies the low resolution latitude associated with the client's IP address
* ClientLocation.longitude — supplies the low resolution longitude associated with the client's IP address
* ClientLocation.address.city — supplies the name of the city associated with the client's IP address
* ClientLocation.address.country — supplies the name of the country associated with the client's IP address
* ClientLocation.address.country_code — supplies the name of the ISO 3166-1 country code associated with the client's IP address
* ClientLocation.address.region — supplies the country specific region name associated with the client's IP address
