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

Question

我正在用 Ruby 编写一个简单的程序来检查域列表是否被占用。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

程序不断出错(即使我在 google.com 中进行硬编码)，并打印以下消息。鉴于该程序非常简单，我已经没有什么想法了 - 有什么建议吗？

/Library/Ruby/Gems/1.8/gems/whois-2.0.2/lib/whois/server/adapters/base.rb:165:in `query_the_socket': Errno::ECONNRESET: Connection reset by peer (Whois::ConnectionError)

这个问题有两种可能的解释:

1. 您在防火墙/代理后面，客户端无法访问服务器
2. (更现实)你的请求被限制了。某些 .COM 服务器(例如 GoDaddy)用于重置连接以防止多次查询。参见 this ticket .您可以通过限制对同一服务器的请求数量来解决此问题。
