使用acceptInsecureCerts与无头铬和硒Webdriver、macOS、Rails、Capybara

Question

headless Chrome可以通过MacOS上的Selenium Webdriver使用自签名证书吗？

我试图让Rails系统测试由SSL上的headless Chrome驱动。

测试设置

# rails_helper.rb
# ... standard rspec rails helper setup omitted ...

Capybara.register_driver(:headless_chrome) do |app|
  options = Selenium::WebDriver::Chrome::Options.new(
    args: %w[--headless --disable-gpu --no-sandbox --disable-web-security]
  )
  capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
    acceptInsecureCerts: true,
  )
  Capybara::Selenium::Driver.new(
    app,
    browser: :chrome,
    options: options,
    desired_capabilities: capabilities
  )
end

RSpec.configure do |config|
  config.before(:each, type: :system) do
    driven_by :headless_firefox
  end
end

module SystemTestHelpers
  def key_file_path
    Rails.root.join("config", "ssl", "ssl-lvh.me.key")
  end

  def cert_file_path
    Rails.root.join("config", "ssl", "ssl-lvh.me.crt")
  end

  def using_app_host(host)
    original_host = Capybara.app_host
    Capybara.app_host = host

    Capybara.server = :puma, {
      Host: "ssl://#{Capybara.server_host}?key=#{key_file_path}&cert=#{cert_file_path}"
    }
    yield
  ensure
    Capybara.app_host = original_host
  end
end

RSpec.configure do |config|
  config.include SystemTestHelpers, type: :system
end

样品测试

# spec/system/welcome_spec.rb

require 'rails_helper'

RSpec.feature "Welcome", :js, type: :system do
  scenario "Visit homepage" do
    using_app_host('https://subdomain.lvh.me') do
      visit "/"

      expect(page).to have_content('Welcome')

      expect(page).to have_content('Your domain: subdomain.lvh.me')
      expect(page).to have_content('Your protocol: https://')
    end
  end
end

页面内容：

<div>
  <h2>Welcome!</h2>

  <p>Your protocol: <%= request.protocol %></p>
  <p>Your domain: <%= request.host %></p>
</div>

Capybara.register_driver(:headless_firefox) do |app|
  options = Selenium::WebDriver::Firefox::Options.new(args: %w[--headless])

  capabilities = Selenium::WebDriver::Remote::Capabilities.firefox(
    acceptInsecureCerts: true,
  )
  Capybara::Selenium::Driver.new(
    app,
    browser: :firefox,
    options: options,
    desired_capabilities: capabilities
  )
end

从您的日志中可以看到，它正在启动chromedriver V2.34。AcceptinSecureCerts直到2.35才添加支持，您应该真正运行最新的（当前为2.41）。更新你的chromedriver版本，事情应该会正常。
