使用 Ruby 机械化 gem 时出现 SSL 重用错误

Question

在出现以下错误之前，我让我的机械化脚本运行了大约 3 个小时：

C:/Ruby193/lib/ruby/gems/1.9.1/gems/net-http-persistent- 
2.7/lib/net/http/persistent/ssl_reuse.rb:29:in `initialize': 
A connection attempt failed because the connected party did not properly 
respond after a period of time, or established connection failed because
connected host has failed to respond. - connect(2) (Errno::ETIMEDOUT)

我假设这是因为它已经运行了 2-3 小时，但想知道是否有人对错误有任何特别的见解

这是我的脚本

require 'rubygems'
require 'mechanize'
def next_button(web_page)
  web_page.page.search('.next a').each do |next_button|
    web_page.click(next_button)
    web_page.page.search('.listing_content').each |info|
      get_info(info)
    end
  next_button(web_page)
  end
end
def get_info(info)
  infos = info.at_css('.url').text.strip
  address = info.css('.street-address').text.strip
  city = info.css('.locality').text.strip
  state = info.css('.region').text.strip 
  zip = info.css('.postal-code').text.strip
end
web_page = Mechanize.new                     
web_page.user_agent_alias = "Linux Firefox"
web_page.get(HOME_URL)
web_page.page.search('.page-navigation a').each do |pagination_link|
 web_page.page.search('.categories-list a').each do |link|  
    web_page.click(link)
    web_page.page.search('.listing_content').each do |info|  
      get_info(info)
    end
    next_button(web_page, worksheet)
  end
  web_page.click(pagination_link)
end    

提前感谢您的任何帮助。

在我看来，持久连接比它们的价值更麻烦。当这种情况发生在我身上时，我会检查以确保我拥有最新版本的 mechanize，如果仍然发生这种情况，我会回退到不使用持久连接的 mechanize 1.0.0。
