IPLibrary ========= 顾名思义，这是一个ip库 Example ======= 本gem中已经带有ip库，默认是gem目录下doc/ip_libraries.txt 默认ip库的格式以IPLibrary::Configuration.separator分组 各组第一行为ip头（192.168.1.1的ip头为192）,其他行各列以英文逗号隔开 各列分别是：起始ip, 结束ip, 省份, 城市, 县区, 行政划分最小字段的拼音(如果有县区则为县区的拼音) 当然，您也可以有自己的ip库 设置ip库的path: IPLibrary::Configuration.file_path = '/home/doc/ip_libraries.txt' 而且，您也可以设置ip库中的列的含义，start_ip、end_ip两列必须有，且必须依次为1、2列 设置其他列：IPLibrary::Configuration.optional_columns = [:province, :city, :district, :pinyin] 除了1、2列，其他列一次为province、city、district、pinyin 然后会动态生成方法： IPLibrary::Base#ip2province IPLibrary::Base#ip2city IPLibrary::Base#ip2district IPLibrary::Base#ip2pinyin ============================================= IPLibrary::Base 的方法有： IPLibrary::Base.ip2province('123.132.254.134') IPLibrary::Base.ip2province(2072313478) #=> "山东" IPLibrary::Base.ip2city('123.132.254.134') IPLibrary::Base.ip2city(2072313478) #=> "临沂" IPLibrary::Base.ip2district('123.132.254.134') IPLibrary::Base.ip2district(2072313478) # => "" IPLibrary::Base.ip2pinyin('123.132.254.134') IPLibrary::Base.ip2pinyin(2072313478) #=> "linyi"
