如何解決HTTP 500錯誤，同時使用Ruby進行機械化報廢？

Question

我想從本網站獲取我的駕駛執照號碼，issue_date和expiry_date（「https://sarathi.nic.in:8443/nrportal/sarathi/HomePage.jsp」）。當我嘗試獲取它時，出現錯誤Mechanize::ResponseCodeError: 500 => Net::HTTPInternalServerError for https://sarathi.nic.in:8443/nrportal/sarathi/DlDetRequest.jsp -- unhandled response。

這是我寫的刮代碼：

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

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE 
agent = Mechanize.new 
agent.log = Logger.new "mech.log" 
agent.user_agent_alias = 'Mac Safari 4' 
Mechanize.new.get("https://sarathi.nic.in:8443/nrportal/sarathi/HomePage.jsp") 

page=agent.get('https://sarathi.nic.in:8443/nrportal/sarathi/HomePage.jsp') # opening home page. 
page = agent.page.links.find { |l| l.text == 'Status of Licence' }.click   # click the link. 
page.forms_with(:name=>"dlform").first.field_with(:name=>"dlform:DLNumber").value="TN3‌​8 20120001119" #user input to text field. 
page.form_with(:name=>"dlform").field_with(:name=>"javax.faces.ViewState").value="SUBMIT" #submit button value assigning. 
page.form(:name=>"dlform",:action=>"/nrportal/sarathi/DlDetRequest.jsp") #to specify the form i need. 
agent.cookie_jar.clear! 
gg=agent.submit page.forms.last #submitting my form

這是行不通的，因爲你是在提交表單前清償的餅乾，因此刪除您所提供的所有輸入數據。我能得到它的工作通過刪除其簡稱爲：

... 

page.forms_with(:name=>"dlform").first.field_with(:name=>"dlform:DLNumber").value="TN3‌​8 20120001119" #user input to text field 

form = page.form(:name=>"dlform",:action=>"/nrportal/sarathi/DlDetRequest.jsp") 
gg = agent.submit form, form.buttons.first 

請注意，您不需要設置#submit按鈕的值，而通過提交按鈕，而提交表單本身。
