ECONNRESET (Whois::ConnectionError) - 尝试在 Ruby 中查询 Whois 时出错
我正在用 Ruby 编写一个简单的程序来检查域列表是否已被占用。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
该程序不断出错(即使我在 google.com 中进行硬编码),并打印下面的消息。鉴于该程序非常简单,我已经没有想法了 - 有什么建议吗?

对此问题有两种可能的解释:
The are two possible explanations to this issue:

param:以前有用吗?
您向 whois 服务器发出过多请求。减速。
之前没有工作吗?

Was it working before?
