基于纯真 IP 库解析**的 IP，参考了“纯真数据库自动更新原理” 和 “PHP 版本的 IP 搜索源码”
Add this line to your application's Gemfile:
gem 'ip_locator_cn'And then execute:
$ bundle
Or install it yourself as:
$ gem install ip_locator_cn
从 Gem 包集成的 qqwry.dat 数据库解析 IP：
2.4.5 :001 > require 'ip_locator_cn'
=> true
2.4.5 :002 > IpLocatorCn.resolve('60.195.153.98')
=> {:province=>"北京", :city=>"顺义区", :country=>"**", :ip=>"60.195.153.98", :county=>"", :isp=>"", :area=>"**北京顺义区后沙峪金龙网吧", :origin_country=>"北京市顺义区", :origin_area=>"后沙峪金龙网吧"}在线下载并解码 qqwry.dat ，然后解析 IP：
2.4.5 :001 > require 'ip_locator_cn'
=> true
2.4.5 :002 > IpLocatorCn.resolve('60.195.153.98', live_dat: true)
=> {:province=>"北京", :city=>"顺义区", :country=>"**", :ip=>"60.195.153.98", :county=>"", :isp=>"", :area=>"**北京顺义区后沙峪金龙网吧", :origin_country=>"北京市顺义区", :origin_area=>"后沙峪金龙网吧"}开启调试信息：
2.4.5 :001 > require 'ip_locator_cn'
=> true
2.4.5 :002 > IpLocatorCn.resolve('60.195.153.98', live_dat: true, debug: true)
