Ruby 使无头浏览器停止加载页面

我发现了一个有趣的功能标志loadAsync，它可能对解决这个问题有用吗？我还不知道如何让watir（webdriver）在启动chromedriver时设置这个。这个标志是在这里介绍的有两种不同的方法可以做你想做的事情，但我会做以下几点：
require 'watir-webdriver'
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 60
@browser = Watir::Browser.new :firefox, :http_client => client
begin
@browser.goto mySite
rescue => e
puts "Browser timed out: #{e}"
end
next_command
mySites = [
mySite1,
mySite2,
mySite3
]
mySites.each do |site|
begin
@browser.goto site
rescue
"Puts #{site} failed to load within the time allotted."
end
end
require 'watir-webdriver'
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 1 #VERY low timeout to make most sites fail
@browser = Watir::Browser.new :firefox, :http_client => client
def testing
begin
@browser.goto "http://www.cnn.com"
rescue => e
puts "Browser timed out on the first example"
end
begin
@browser.goto "http://www.foxnews.com"
rescue => e
puts "Browser timed out on the second example"
end
end
您可以使用AutoIT发送转义键来停止Google加载页面。这与您最初尝试的操作类似，但直接使用AutoIT而不是通过损坏的Watir:：Browser对象
require 'watir-webdriver'
require 'win32ole'
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 5
@browser = Watir::Browser.new :chrome, :http_client => client
begin
@browser.goto "http://www.nst.com.my/"
rescue
autoit = WIN32OLE.new("AutoItX3.Control")
autoit.AutoItSetOption("WinTitleMatchMode", 2)
autoit.WinActivate("Google")
autoit.Send("{ESC}")
end
@browser.goto "http://www.google.ca"
注意：我试图让
autoit.ControlSend（“Google”，“”，“”，“{ESC}”）require 'watir-webdriver'
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 5
@browser = Watir::Browser.new :firefox, :http_client => client
@browser.goto "twitter.com"
#after the page loads, log in
def test
begin
temp = []
temp = @browser.cookies.to_a
@browser.goto "twitter.com:81"
rescue => e
puts "Browser timed out"
@browser.close
@browser = Watir::Browser.start "twitter.com"
temp.each do |me|
@browser.cookies.add(me[:name], me[:value])
end
@browser.refresh
end
end
保存和恢复cookie的额外代码将允许您保持登录到正在使用的站点。这很糟糕，但这是我能想到的唯一解决办法。这还是2012年的事，所以如果有人发现任何更好的方法，请纠正我 我也有超时的问题。我从在线研究中了解到，SeleniumWebDriver遇到超时后，状态会变差并出现错误（多线程问题）。我遵循了以下建议：
我实施了主动杀戮（而不是browser.close）并在任何异常救援后重新启动
Watir:：browser
