我是Rails的新手，想尝试Ruby Whois gem。
我定义了一个用于创建报告的活动记录。然后，该报告将填充来自whois查询的数据（最好是经过解析的）。
当我进行查询时，我会得到一些非常奇怪的东西。我使用ByeBug作为调试器：
$ (byebug) Whois.whois("google.it")

我想知道这一切是怎么回事。它的结构与IRB或简单控制台中的结构不同。
当我尝试查看房产时，它只是告诉我赶紧离开：
$ (byebug) Whois.whois("google.it").property_supported?(:domain)
NoMethodError Exception: undefined method `property_supported?' for #<Whois::Record:0x000000065aba08>
nil
我在一台运行Rails 4.0和Ruby 2.1.2版本的虚拟机（Ubuntu precise64）上。web服务器是默认的Webrick。
我想做的就是获取对象<Whois::Record>并从中提取值，例如domain、domain_id、registrator等等…有什么技巧吗？
#whois方法返回一个Whois::Record对象，该对象封装whois响应字符串并提供解析功能。您在控制台中看到的输出只是对象表示。
record = Whois.whois("google.it")
record.class
# => Whois::Record
Record文档说明了如何使用该对象。例如，要打印出其String表示，请显式调用puts或使用.to_s。
puts record.to_s
如果需要访问特定的属性，则不需要调用解析器。只需访问该物业。
record.expires_on
# => 2015-04-21 00:00:00 +0200
请务必阅读库文档。
-
控制台中的输出显示，进行调用将返回预期的输出（设置
@record）。 -
property_supported?无法工作，因为该方法在此类型的对象上不可用。
此外，我从未听说过夜蛾
您是否能够从应用程序的根目录执行rails console并尝试在那里使用对象？
