如何在 Ruby 中使用 Mechanize 提交表單？

Question

當我運行此代碼時：

require 'mechanize'
require 'logger'
require 'nokogiri'
require 'open-uri'

agent = Mechanize.new
agent.log = Logger.new "mech.log"
agent.user_agent_alias = 'Mac Safari'
agent.verify_mode = OpenSSL::SSL::VERIFY_NONE
page = agent.get('https://sarathi.nic.in:8443/nrportal/sarathi/HomePage.jsp')
page = agent.page.links.find{|i| i.text == "Status of Licence"}.click
page.form(:name=>"dlform").field_with(:name=>"dlform:DLNumber").value="TN4020120005045"
page.submit

我收到此錯誤：

NoMethodError: undefined method `submit' for #<Mechanize::Page:0x8e644cc>

我該如何解決這個問題？

@sudhagar，您應該提交form而不是page 。 還將其分解為更清晰的代碼的單獨調用，如：

...
form = page.form(:name=>"dlform")
form.field_with(:name=>"dlform:DLNumber").value="TN4020120‌​005045"
form.submit 
...
