描述中提到的使用selenium驱动程序的代码能否在机械化中实现?

Question

谁能给我一些小提示，提到如何在Mechanize中编写以下内容?我对宝石Mechanize完全陌生。

require "rubygems"
require "selenium-webdriver"
driver = Selenium::WebDriver.for :firefox
driver.get "https://www.example.com/"
element = driver.find_element :name => "username"
element.send_keys "#####"
element = driver.find_element :name => "password"
element.send_keys "******"
element.submit
element = driver.find_element(:name, "btnHome")
element.click
element=driver.find_element(:link, "Empdetals")
#print element.attribute(:href)
element.click
element = driver.find_element :name => "search.empdirectory"
element.send_keys "#######"
element = driver.find_element :name => "btnSearch"
element.click
driver.current_url

是的，mechanize gem可用于自动与网站进行任何交互，包括通过提交用户名/密码和点击提交按钮/链接等登录到网站

不像selenium-webdriver直接调用浏览器，mechanize本身充当浏览器。

一定要查看mechanize文档中的EXAMPLES页面，以了解如何使用mechanize。第二个例子——使用RubyForge——展示了如何登录到一个站点并使用生成的页面。

关于如何使用mechanize的快速概述，请查看RailsCasts关于mechanize的一集

下面是一个示例代码，从http://www.google.com开始，点击"Gmail"文本，登录Gmail，并列出页面内的链接:

require 'mechanize'
a = Mechanize.new
a.get('http://www.google.com') do |page|
  # Click the Gmail link
  gmail_login_page = a.click(page.link_with(:text => "Gmail"))
  # Submit the login form
  gmail_page = gmail_login_page.form_with( :action => 'https://accounts.google.com/ServiceLoginAuth' ) do |f|
    f.Email  = "<username>@gmail.com"
    f.Passwd = "**********"
  end.click_button
  # List all the links in the personal gmail page
  gmail_page.links.each do |link|
    text = link.text.strip
    next unless text.length > 0
    puts text
  end
end

希望它有助于开始使用Mechanize并进一步探索它!
