ruby - 使用 headless chrome 和 watir webdriver

Question

在 watir 文档 ( http://watir.com/guides/chrome/ ) 中，已经提到做

Watir::Browser.new :chrome, headless: true

将使我们能够使用 headless chrome

这似乎行不通。

我收到如下错误

2.4.0 :001 > require 'watir'
 => true 
2.4.0 :002 > Watir::Browser.new :chrome, headless: true
ArgumentError: unknown option: {:headless=>true}

我的chrome版本是59.0.3071.115

我的 chrome 驱动版本是

ChromeDriver 2.20.353124 (035346203162d32c80f1dce587c8154a1efa0c3b

使用

selenium-webdriver 3.4.3

watir 6.7.1 (was 6.3.0)

更新你的 gem 并尝试这样的事情:

driver = Watir::Browser.new :chrome, :switches => %w[--ignore-certificate-errors --disable-popup-blocking --disable-translate --disable-notifications --start-maximized --disable-gpu --headless]
driver.driver.manage.timeouts.implicit_wait = 100 # seconds

--disable-gpu 和 --headless 为 chrome 启用 headless 。

试一试。谢谢。
