我没有经验丰富的Ruby + Mechanize，刚刚开始，所以...请帮忙。 我试图用动态内容填写表单。但是我不能一步一步地做到这一点。
那是我的代码：
#!/usr/bin/env ruby
# encoding: utf-8
require 'rubygems'
require 'mechanize'
require 'logger'
url = "https://visapoint.eu/visapoint2/disclaimer.aspx"
agent = Mechanize.new
agent.user_agent_alias = 'Mac Safari'
agent.log = Logger.new(STDOUT)
page = agent.get(url)
page.encoding = 'utf-8'
# Disclamer.aspx object page
disclamer_page = agent.page
# Click Accept button on Disclamer.aspx
accept_button = disclamer_page.form.button_with(:value =>'Accept')
action_page = disclamer_page.form.click_button( accept_button )
# Click New Appointment button on Action.aspx
new_appointment_button = action_page.form.button_with(:name => 'ctl00$cphMain$btnNewAppointment_input')
form_page = action_page.form.click_button ( new_appointment_button )
# Fill form on Form.aspx page
form_page.form['ctl00$cphMain$ddCitizenship'] = "Kazakhstan (Қазақстан)"
form_page.form['ctl00$cphMain$ddCountryOfResidence'] = "Kazakhstan (Қазақстан)"
form_page.form['ctl00$cphMain$ddEmbassy'] = "#Kazakhstan (Қазақстан) - Astana"
form_page.form['ctl00$cphMain$ddVisaType'] = "Long-stay visa for study"
pp form_page.form
formpage_next = agent.submit(form_page.form, form_page.form.buttons.last)
pp formpage_next
发送form_page后，我希望重新加载的页面有验证码，但那里什么都没有。
