我正在学习使用Selenium来做基本的事情,例如截取屏幕,抓取和测试,并希望将它与无头Chrome一起使用,Chrome现在从Chrome 59开始就是稳定的.
我已经能够使用’selenium-webdriver’宝石和chromedriver截取屏幕截图,但不是无头. 这是我正在运行的ruby脚本,它在开始初始化驱动程序后挂起 require 'rubygems'
require 'selenium-webdriver'
Selenium::WebDriver.logger.level = :debug
p 'initializing driver'
driver = Selenium::WebDriver.for :chrome,switches: %w[--headless --disable-gpu --screenshot --hide-scrollbars]
p 'navigating to Google'
driver.navigate.to "http://google.com"
driver.save_screenshot("./screen.png")
driver.quit
和日志的输出： :> ruby rubytest.rb
"initializing driver"

[RUBY BACKTRACE TO DRIVER INITIALIZATION]
我尝试使用类似代码的JavaScript和Python驱动程序,没有任何作用.当我尝试使用Python时,错误消息是 WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally (Driver info: chromedriver=2.29.461585 (0be2cd95f834e9ee7c46bcc7cf405b483f5ae83b),platform=Mac OS X 10.12.5 x86_64) 解决方法
我发现
this blog post可用于在ruby中设置无硒铬硒
require "selenium-webdriver"
# configure the driver to run in headless mode
options = Selenium::WebDriver::Chrome::Options.new
options.add_argument('--headless')
driver = Selenium::WebDriver.for :chrome,options: options
driver.navigate.to "https://www.google.com"
# resize the window and take a screenshot
driver.manage.window.resize_to(800,800)
driver.save_screenshot "screenshot.png"
