ruby - 将 Mechanize 与 Google 文档结合使用

Question

我正在尝试使用 Mechanize 登录 Google 文档，以便我可以抓取一些东西(无法从 API 中获取)，但在尝试遵循元重定向时，我似乎一直收到 404:

require 'rubygems'
require 'mechanize'

USERNAME = "..."
PASSWORD = "..."

LOGIN_URL = "https://www.google.com/accounts/Login?hl=en&continue=http://docs.google.com/"

agent = Mechanize.new
login_page = agent.get(LOGIN_URL)
login_form = login_page.forms.first
login_form.Email = USERNAME
login_form.Passwd = PASSWORD
login_response_page = agent.submit(login_form)

redirect = login_response_page.meta[0].uri.to_s

puts "redirect: #{redirect}"

followed_page = agent.get(redirect) # throws a HTTPNotFound exception

pp followed_page

谁能看出为什么这不起作用？

安迪你太棒了!!您的代码帮助我使我的脚本可行并登录到谷歌帐户。几个小时后我发现了你的错误。这是关于 html 转义的。正如我发现的那样，Mechanize 会自动转义它作为“get”方法的参数接收的 uri。所以我的解决方案是:

EMAIL  = ".."
PASSWD = ".."
agent = Mechanize.new{ |a| a.log = Logger.new("mech.log")}
agent.user_agent_alias = 'Linux Mozilla'
agent.open_timeout = 3
agent.read_timeout = 4
agent.keep_alive   = true
agent.redirect_ok  = true
LOGIN_URL = "https://www.google.com/accounts/Login?hl=en"

login_page = agent.get(LOGIN_URL)
login_form = login_page.forms.first
login_form.Email = EMAIL
login_form.Passwd = PASSWD
login_response_page = agent.submit(login_form)

redirect = login_response_page.meta[0].uri.to_s

puts redirect.split('&')[0..-2].join('&') + "&continue=https://www.google.com/"
followed_page = agent.get(redirect.split('&')[0..-2].join('&') + "&continue=https://www.google.com/adplanner")
pp followed_page

这对我来说很好用。我已将元标记(已转义)中的 continue 参数替换为新参数。
