ECONNRESET(Whois :: ConnectionError) - 尝试在Ruby中查询Whois时出错

Question

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？

Answer 1

对这个问题有两种可能的解释：

1. 您位于防火墙/代理之后，客户端无法访问服务器
2. （更现实）您的请求被限制。某些.COM服务器（例如GoDaddy）用于重置连接，以防止出现多个查询。看这张票。您可以通过限制对同一服务器的请求数来解决此问题。

Answer 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
