filex = File.open(logfile, "w+")

File.foreach(ARGV[0]) do |line|
    line = line.gsub("\n", "")
    result = `curl "http://api.map.baidu.com/location/ip?ak=xxxx&ip=#{line}"`
    puts  "http://api.map.baidu.com/location/ip?ak=xxxx&ip=#{line}"
    puts result
  begin
        filex << "#{line}:#{JSON.parse(result)["content"]["address_detail"]["province"] }  #{JSON.parse(result)["content"]["address_detail"]["city"] }"
