我想从访问者的IP地址中提取用户国家/地区名称.

I want to extract a user country name from visitors' IP addresses.

我可以用remote_ip来获取IP地址.但是可能是什么 最简单的获取国家名称的方法?

I could get the IP address with remote_ip. But what could be the easiest way to get the country name?

它不一定是超级准确的.任何红宝石库(gem或插件)都可以做到这一点?

It doesn't have to be super accurate. Any ruby library (gem or plugin) to do this?

推荐答案

您可以使用geoip gem.

environment.rb

environment.rb

config.gem 'geoip'

从http://www.maxmind.com/app/geolitecountry下载GeoIP.dat.gz.解压缩文件.下面假设在#{RAILS_ROOT}/db目录下.

Download GeoIP.dat.gz from http://www.maxmind.com/app/geolitecountry. unzip the file. The below assumes under #{RAILS_ROOT}/db dir.

@geoip ||= GeoIP.new("#{RAILS_ROOT}/db/GeoIP.dat")    
remote_ip = request.remote_ip 
if remote_ip != "127.0.0.1" #todo: check for other local addresses or set default value
  location_location = @geoip.country(remote_ip)
  if location_location != nil     
    @model.country = location_location[2]
  end
end
