新学watir的小白,正常运行一段时间后,就会报错,不用thread也一样,请各位大神指导一下😂

代码如下:

def get_post_link_by_slice(page_slice)
  b = Watir::Browser.new :phantomjs

  page_slice.each do |page|
   b.goto page

   links = b.ul(class: "text-list").lis
   links.each do |li|
    link = li.a.href
    if link.end_with?('html') && link.include?('trsyw')
     puts "#{page} #{link}"
    end
   end
  end

  b.close
end

pages = get_pages()

threads = []
pages.each_slice(300) do |s|
  threads << Thread.new do
   get_post_link_by_slice(s)
  end
end

threads.each { |t| t.join }

报错如下:

最近在用watir也遇到过这个错误,不过我也不知道是为啥。建议你在get_post_link_by_slice函数里加一个异常处理,把错误打印出来,看看是哪里出问题了。

错误就是“ Net::ReadTimeout”,谢谢。我直接rescue了retry
