[英]Using acceptInsecureCerts with Headless Chrome and Selenium Webdriver, macOS, Rails, Capybara
Does headless Chrome work with self-signed certificates via the Selenium Webdriver on macOS? 无头Chrome是否可以通过macOS上的Selenium Webdriver使用自签名证书?
I am attempting to get Rails system tests driven by headless Chrome over SSL. 我试图让无头Chrome通过SSL驱动Rails系统测试。
I have a locally self-signed certificate that I pass the the ruby Puma application server to terminate SSL requests. 我有一个本地自签名证书,我通过ruby Puma应用程序服务器来终止SSL请求。 In order to allow drivers to ignore SSL warnings on the locally signed certificate, I am using the
acceptInsecureCerts
flag to configure the driver capabilities. 为了允许驱动程序忽略本地签名证书上的SSL警告,我使用
acceptInsecureCerts
标志来配置驱动程序功能。 I'm led to believe by this ticket in Chromium that this flag should be recognized as of Chrome 64+. 我被Chromium的这张票证相信,这个标志应该被识别为Chrome 64+。
I can get tests to succeed with Chrome, Firefox, and headless Firefox. 我可以通过Chrome,Firefox和无头Firefox获得成功的测试。 Tests do not pass under headless Chrome.
测试不会通过无头Chrome。 I am using (at the time of this writing) what I believe to be the latest versions of Chrome and its variants.
我正在使用(在撰写本文时)我认为最新版本的Chrome及其变体。
Though folks in the Chromium ticket appear to be successfully running headless Chrome over locally-signed SSL with the Selenium webdriver, I have not found this to work with the setup described here. 虽然Chromium票证中的人员似乎是通过Selenium webdriver在本地签名的SSL上成功运行无头Chrome,但我还没有发现这可以使用此处描述的设置。 If my configuration is correct, then I am unsure if there is a limitation in headless Chrome on macOS, in Selenium webdriver ruby gem, or something else I haven't considered.
如果我的配置是正确的,那么我不确定macOS上的无头Chrome,Selenium webdriver ruby gem或其他我没有考虑的其他内容是否有限制。 If anyone has something similar working with Rails on macOS, I'd be interested to learn about your setup.
如果有人在macOS上使用类似Rails的东西,我有兴趣了解你的设置。
Here is some code to show how I am configuring and running my RSpec/Capybara tests. 下面是一些代码,用于说明我如何配置和运行RSpec / Capybara测试。
Test setup 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
Sample test 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
Page content: 页面内容:
<div>
<h2>Welcome!</h2>
<p>Your protocol: <%= request.protocol %></p>
<p>Your domain: <%= request.host %></p>
</div>
If I swap out the driver for headless Firefox, configured as below, the tests will pass. 如果我换掉无头Firefox的驱动程序,配置如下,测试将通过。
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

Here's a link to some debug output from running the test in either headless Chrome or headless Firefox: https://gist.github.com/rossta/b160204baa87a520e7888c19c8b1ed98 . 以下是在无头Chrome或无头Firefox中运行测试的一些调试输出的链接: https : //gist.github.com/rossta/b160204baa87a520e7888c19c8b1ed98 。
Note in the output that the session response does not include the 'acceptInsecureCerts' capability for Chrome (test-headless-chrome.log, line 15) while in Firefox we do see the session include the flag (test-headless-firefox.log, line 22). 请注意输出中的会话响应不包含Chrome的“acceptInsecureCerts”功能(test-headless-chrome.log,第15行),而在Firefox中我们确实看到会话包含标志(test-headless-firefox.log,第22行)。

acceptInsecureCerts
support wasn't added until 2.35 and you should really be running the latest (2.41 currently). 在2.35之前没有添加
acceptInsecureCerts
支持,你应该真正运行最新的(当前为2.41)。 Update your version of chromedriver and things should work. 更新你的chromedriver版本,事情应该有效。
