可以使用Selenium驅動描述的代碼在機械化中實現嗎？

Question

任何人都可以通過提供小提示提及如何在Mechanize中寫下如何幫助我？我對Gem 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

Answer 1

是，mechanize gem可用於自動化與網站進行任何交互，包括登錄到網站通過提交用戶名/密碼並點擊提交按鈕/鏈接等。

與selenium-webdriver不同，它可以直接調用瀏覽器，mechanize本身充當瀏覽器。

結賬EXAMPLES page on mechanize documentation瞭解如何使用mechanize。第二個示例 - RubyForge - 顯示如何登錄到網站並使用生成的頁面。

在這裏工作的簡要概述爲開始http://www.google.com，點擊「Gmail的」文本，登錄Gmail，並列出網頁內的鏈接的示例代碼：

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 

希望它有助於開始Mechanize並探索它！
