Rails 如何实现通过登录IP确定城市功能 博客分类： RubyOnRails
Rails Ruby Git Google XML
对于Rails而言，主流方式应该是使用google库的插件geoip
github地址如下
Ruby代码
require 'geoip' GeoIP. new ( 'GeoLiteCity.dat' ).country( 'HdhCmsTestatlantis.sk' ) => [ "HdhCmsTestatlantis.sk" , "217.67.18.26" , "SK" , "SVK" , "Slovakia" , "EU" , "02" , "Bratislava" , "" , 48.15, 17.1167, nil , nil , "Europe/Bratislava" ] Returned values are the requested hostname, the IP address as a dotted quad, Maxmind's country code, the ISO3166-1 country code, the ISO3166-2 country code, the ISO3166 country name, and the continent code. GeoIP. new ( 'GeoCity.dat' ).city( 'github测试数据' ) => [ "github测试数据" , "207.97.227.239" , "US" , "USA" , "United States" , "NA" , "CA" , "San Francisco" , "94110" , 37.7484, -122.4156, 807, 415, "America/Los_Angeles" ] Returned values are the country values followed by region or state name, city name, postal_code/zipcode, latitude, longitude, USA DMA code, USA area code, timezone name. Sorry it's not a Hash ... historical. GeoIP. new ( 'GeoIPASNum.dat' ).asn( "HdhCmsTestfsb.ru" ) => [ "AS8342" , "RTComm.RU Autonomous System" ]另外一个 geo_ip
使用如下：
Ruby代码
GeoIp.geolocation(ip_address)Ruby代码
# 209.85.227.104 = google.be (US) GeoIp.geolocation( '209.85.227.104' ) #returns: { :status => "OK" , :ip => "209.85.227.104" :country_code => "US" , :country_name => "United States" , :region_code => "06" , :region_name => "California" , :city => "Mountain View" , :zip_postal_code => "94043" , :latitude => "37.4192" , :longitude => "-122.057" }geokit 是一个关于地理的工具，比如根据经纬度确定城市和距离之类
Ruby代码
#Find near latitude and longitude: Store.find( :all , :origin =>[37.792,-122.393], :within =>10) #Find near an address: Store.find( :all , :origin => '100 Spear st, San Francisco, CA' , :within =>10) #Order by distance from the center of a zipcode: Store.find( :all , :origin => '94117' , :within =>10, :order => 'distance asc' ) #Combine distance conditions with regular conditions Store.find( :all , :origin => '94117' , :within =>10, :conditions =>{ :store_type => 'CAFE' })一个是通过网络的IP查询API，这个办法IP库更新比较快。通用的库有几个比如google。
xml处理页面完全可以通过nokogiri等专门处理工具代替
提供IP地址查询的API很多比如网易
http://HdhCmsTestyoudao测试数据/smartresult-xml/search.s?type=ip&q=IP地址
Ruby代码
require 'net/http' require 'rexml/document' include REXML class MapsController < ApplicationController def index @location = locateIp() end def locateIp #ip = "123.123.123.123"; ip = request.remote_ip ips = ip.to_s url = "http://ipinfodb测试数据/ip_query.php?ip=" +ips+ "&timezone=false" xml_data = Net::HTTP.get_response(URI.parse(url)).body xmldoc = REXML::Document. new (xml_data) # Now get the root element root = xmldoc.root city = "" regionName = "" countryName = "" # This will take country name... xmldoc.elements. each ( "Response/CountryName" ) { |e| countryName << e.text } # Now get city name... xmldoc.elements. each ( "Response/City" ) { |e| city << e.text } # This will take regionName... xmldoc.elements. each ( "Response/RegionName" ) { |e| regionName << e.text } ipLocation = city + ", " +regionName+ ", " +countryName return ipLocation end #end of method locateIp end
mac安装rmagic | Nokogiri 中文乱码的几种情况
