无法使用 ruby selenium webdriver 连接到浏览器 [英] Unable to connect to browser using ruby selenium webdriver
问题描述
我尝试使用 ruby selenium webdriver 运行一些基本的自动化测试.相同的代码在我的家用计算机上运行良好，但在我的工作计算机上运行失败，它位于代理后面(不需要身份验证).
I tried to run some basic automated tests using ruby selenium webdriver. The same code works perfectly on my home computer, but fails on my work computer which is behind a proxy (which doesn't require authentication).
driver = Selenium::WebDriver.for :firefox, :profile => 'default'
driver = Selenium::WebDriver.for :firefox, :profile => 'default'
我得到的错误是:
C:/Ruby193/lib/ruby/gems/1.9.1/gems/selenium-webdriver-2.24.0/lib/selenium/webdriver/remote/http/common.rb:66:in `create_response': unexpected response, code=

浏览器以正确的配置文件打开，但生成的驱动程序变量为零.我什至尝试在配置文件上手动设置代理，但没有运气.
The browser opens with correct profile, but resulting driver variable is nil. I even tried to manually setup the proxy on the profile with no luck.
有什么想法吗?
推荐答案
您的环境中可能设置了 HTTP_PROXY(或 http_proxy).selenium-webdriver (2.25) 的下一个版本也将支持 NO_PROXY/no_proxy(然后您可以将其设置为 NO_PROXY=127.0.0.1).在此之前，您可以在启动浏览器之前从 Ruby 环境中删除代理:
You probably have HTTP_PROXY (or http_proxy) set in your environment. The next release of selenium-webdriver (2.25) will also honor NO_PROXY/no_proxy (which you can then set to NO_PROXY=127.0.0.1). Until then you can remove the proxy from the Ruby environment before launching the browser:
ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox
如果您需要为 Firefox 配置代理与外界通信，您可以尝试如下操作:
If you need the proxy configured for Firefox to communicate with the outside world, you could try something like this:
proxy = Selenium::WebDriver::Proxy.new(:http => ENV['HTTP_PROXY'] || ENV['http_proxy'])
ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox, :proxy => proxy
