Answer 1

对于像这样模拟Web浏览器体验的任务,我使用了mechanize gem.它的工作原理如下:

require 'rubygems'
require 'mechanize'

www = Mechanize.new
www.get('http://your.site/path/to/login/page') do |login_page|
    inside_page = login_page.form_with(:action => '/path/to/login/form/action') do |f|
        f.form_username_element_name = "username"
        f.form_password_element_name = "password"
    end.click_button

    # Do stuff with "inside_page", like navigate, scrape links, etc...
    # See the mechanize docs for details
end
