我正在Ruby中编写一个简单的程序来检查是否采用了域列表。基本上它循环遍历列表,并使用以下函数进行检查。
require 'rubygems'
require 'whois'
def check_domain(domain)
c = Whois::Client.new
c.query("google.com").available?
end
该程序不断出错(即使我在google.com上进行硬编码),并打印下面的消息。鉴于该计划有多简单,我已经没有想法 - 任何建议?

这个问题有两种可能的解释:
答案 1 :(得分:2)
尝试使用timeout
参数:
irb(main):002:0> c = Whois::Client.new(:timeout => 100) # 100 seconds
irb(main):003:0> c.query("google.com").available?
=> true

之前有效吗? 您向whois服务器发出的请求太多了。慢下来。
之前没有工作? 你无法访问whois服务器
