Capybara Poltergeist 无法使用 StatusFailError 在 vpn 中加载站点答案

【问题标题】：Capybara Poltergeist failing to load site inside vpn with StatusFailErrorCapybara Poltergeist 无法使用 StatusFailError 在 vpn 中加载站点

【问题描述】：

我正在尝试设置 Poltergeist 以在我们公司的 CI 系统中进行无头测试。

当我在我们的内部服务器上使用 Poltergeist 时，看起来远程站点正在立即关闭连接。知道为什么吗？

Google.com 很好，用 Chrome 进行测试也可以。

当错误发生时，它会立即发生（不会长时间超时）。下面是调试信息。

这是我的浏览器设置：

 when 'poltergeist'
      Capybara.register_driver :poltergeist do |app|
        options = { 
          :debug => true,
          :phantomjs_options => [
            '--ignore-ssl-errors=yes',
            '--debug=true',
          ]
        } 
        Capybara::Poltergeist::Driver.new(app, options)
      end
      Capybara.default_driver = :poltergeist

Poltergeist 1.13.0、Capybara 2.6.2、Ruby 2.1.7-p400、OSX 10.11.6。谢谢！

【解决方案1】：

这段代码解决了这个问题。我怀疑这是一个 SSL 安全问题，并且 ssl-protocol=any 选项修复了它。

从现在开始，我将把它用于我所有的错误:)

    phantomjs_options: [
      '--proxy-type=none', 
      '--load-images=no', 
      '--ignore-ssl-errors=yes', 
      '--ssl-protocol=any',
      '--web-security=false',
      '--debug=true
    ]
