我关注Mechanize guide，但无法提交表单。 我的想法是通过Telegram bot通过查询获取发票。由于有一个验证码，我以为我可以通过Mechanize读取验证码图像src，通过Telegram发送该图像。然后，我会输入我可以在图像上看到的数字并发回到Mechanize以填充第二个输入字段。 代码：
require 'mechanize'
agent = Mechanize.new
agent.user_agent_alias = 'Windows Chrome'
page = agent.get('https://ercdmd.ru/?gpay')
form = page.forms.first
form.gpay_abon = '04-0000000000'
captcha_url = "https://ercdmd.ru/captcha.php?time=#{Time.now.to_i}000"
p captcha_url
captcha = gets.chomp
form.captcha = captcha
page = agent.submit(form, form.buttons.first)
输出：
