watir-webdriver在保持浏览器打开的情况下更改代理 [英] watir-webdriver change proxy while keeping browser open

问题描述

我正在使用Ruby中的Watir-Webdriver库检查一些页面。我知道我可以通过代理连接使用

  profile = Selenium :: WebDriver :: Firefox :: Profile.new＃create a新配置文件
 profile.proxy = Selenium :: WebDriver :: Proxy.new（＃为配置文件创建代理数据
：http => proxyadress，
：ftp => nil， 
：ssl => nil，
：no_proxy => nil 
）
 browser = Watir :: Browser.new：firefox，：profile => profile＃用这个配置文件创建一个浏览器窗口
 browser.gotohttp://www.example.com
 browser.close 
   
 
所以，我的问题：有没有什么办法可以改变，在ruby中使用webdriver，代理地址Firefox使用连接通过，同时保持浏览器打开？ 
解决方案
如果你想测试一个页面是否被阻止当通过代理服务器进行访问时，可以通过无头库实现。我最近使用机械化取得了成功。您也可以使用net / http。
 
 
我还不确定为什么您需要更改当前会话的代理服务器。  
 
 $ p $  require'Mechanize'
 session = Mechanize.new 
 session.set_proxy（host，port，user ，pass）
 session.user_agent ='Mac Safari'
 session.agent.robots = true #observe of robots.txt rules 
 response = session.get（url）
 puts response.code 
  

您需要提供代理 host / port / user / pass < （用户/密码是可选的）和 url 。如果你得到一个异常，那么response.code可能不友好。

I am using the Watir-Webdriver library in Ruby to check some pages. I know I can connect through a proxy using

profile = Selenium::WebDriver::Firefox::Profile.new#create a new profile
profile.proxy = Selenium::WebDriver::Proxy.new(#create proxy data for in the profile
  :http => proxyadress,
  :ftp => nil,
  :ssl => nil,
  :no_proxy => nil
)
browser = Watir::Browser.new :firefox, :profile => profile#create a browser window with this profile
browser.goto "http://www.example.com"
browser.close

However, when wanting to connect to the same page multiple times using different proxies, I have to create a new browser for every proxy. Loading(and unloading) the browser takes quite some time.

So, my question: Is there any way to change, using webdriver in ruby, the proxy adress Firefox uses to connect through while keeping the browser open?

解决方案

If you want to test whether a page is blocked when accessed through a proxy server, you can do that through a headless library. I recently had success using mechanize. You can probably use net/http as well.

I am still not sure why you need to change the proxy server for a current session.

require 'Mechanize'
session = Mechanize.new
session.set_proxy(host, port, user, pass)   
session.user_agent='Mac Safari'
session.agent.robots = true #observe of robots.txt rules
response = session.get(url)
puts response.code

You need to supply the proxy host/port/user/pass (user/pass are optional), and the url. If you get an exception, then the response.code is probably not friendly.
