HomeBackend DevelopmentPHP Tutorialjavascript - ip地址如何转换为经纬度坐标?

最近,在做地图相关的应用。
有大量的用户数据是ip地址,如果把用户标记在地图上,需要把ip地址转换为经纬度坐标。
请问有没有可行的办法实现?

我曾经做过一个类似的事情,使用的方案比较折腾:

  • Nginx 有 geoip 的模块,检查安装的 Nginx 是否编译了这个模块。
nginx -V

nginx version: nginx/1.1.19
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --lock-path=/var/lock/nginx.lock --pid-path=/var/run/nginx.pid --with-debug --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_realip_module --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-http_xslt_module --with-ipv6 --with-sha1=/usr/include/openssl --with-md5=/usr/include/openssl --with-mail --with-mail_ssl_module --add-module=/build/buildd/nginx-1.1.19/debian/modules/nginx-auth-pam --add-module=/build/buildd/nginx-1.1.19/debian/modules/nginx-echo --add-module=/build/buildd/nginx-1.1.19/debian/modules/nginx-upstream-fair --add-module=/build/buildd/nginx-1.1.19/debian/modules/nginx-dav-ext-module

如果是没有重新编译一个带 geoip 模块的 Nginx 使用。

  • Nginx 的配置文件配置 geoip 的数据库,geoip 的数据库有收费的,也有免费的下载,我都是用免费的,经常更新一下即可。
http {
        geoip_country  /etc/nginx/GeoIP.dat;
        geoip_city     /etc/nginx/GeoLiteCity.dat;
}
  • GEO 的信息就可以通过fastcgi的参数传递给应用了,以下是Django的一段 fastcgi 配置示例。
#GeoIP
fastcgi_param GEOIP_COUNTRY_CODE $geoip_city_country_code;
fastcgi_param GEOIP_COUNTRY_CODE3 $geoip_country_code3;
fastcgi_param GEOIP_COUNTRY_NAME $geoip_country_name;
fastcgi_param GEOIP_CITY_COUNTRY_CODE $geoip_city_country_code;
fastcgi_param GEOIP_CITY_COUNTRY_CODE3 $geoip_city_country_code3;
fastcgi_param GEOIP_CITY_COUNTRY_NAME $geoip_city_country_name;
fastcgi_param GEOIP_REGION $geoip_region;
fastcgi_param GEOIP_CITY $geoip_city;
fastcgi_param GEOIP_POSTAL_CODE $geoip_postal_code;
fastcgi_param GEOIP_CITY_CONTINENT_CODE $geoip_city_continent_code;
fastcgi_param GEOIP_LAT $geoip_latitude;
fastcgi_param GEOIP_LNG $geoip_longitude;
  • Django 把得到的经纬度通过 Ajax 传递到前台,交给 Google Map API 显示即可。如果是国内的 IP 可能就不准确,我用了纯真IP的数据库,方法 Google 一下有很多。

这个方法的限定是使用 Nginx + fastcgi,不是适合所有的人。

无意义。ip地址转换过来是城市信息。城市信息得到的经纬度是地区行政规划中心点。

我也有做IP 地理位置查询站点的想法。

查了下,http://www.iplocationtools.com/ 这个API 看起来比较靠谱。
此网站 http://www.ipgeo.com/ 也号称提供API,但是API 的域名都无法解析。
SAE 也提供付费的接口。

看看这个有没有帮助 https://developers.google.com/maps/do...

返回JSONP数据。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
