连接被 phantomjs 拒绝了 Watir webdriver

Question

Watir gem 有问题，线程中运行。基本上它看起来像这样：我正在创建线程（假设有三个线程）。然后我正在创建新的浏览器，访问网页并尝试关闭该浏览器。在 2-3 小时内一切正常，然后我收到此错误（browser.close 导致此错误）：

Errno::ECONNREFUSED: Connection refused - Connection refused

            close at /home/ubuntu/.rvm/gems/jruby-9.0.4.0/gems/watir-webdriver-0.9.1/lib/watir-webdriver/browser.rb:136

这是代码：

THREAD_COUNT.times.map {
  Thread.new(links) do |links|
    while link = mutex.synchronize { links.pop }
      counter = 0
      sleep(rand 1..50)
      browser = Watir::Browser.new :phantomjs, :args => %w(--ssl-protocol=tlsv1 --ignore-ssl-errors=yes)
      begin
       result = function(browser)
      rescue
       counter += 1
       retry if counter > 2
      end
      browser.close
    end
  end
}.each(&:join)

我是运行这个 ubuntu 和 jruby 9.0.4.0 正如这里所建议的，我添加了睡眠 Opening several threads with watir-webdriver results in 'Connection refused' error 但它不起作用

Answer 1

如您所见，我在 while 循环中创建了新的浏览器实例。有时它无法按时关闭该浏览器或发生其他与 pid 相关的故障。最好创建固定数量的浏览器（例如 THREAD_COUNT 次）并在可用时重用它。因此，在 THREAD_COUNT.times.map 之后立即创建浏览器将为每个线程提供一个浏览器实例。
