Hi guys,

I’m trying to submit a form to the following website  
([http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do](http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do)) and just want to print  
out the result.

Here’s the code that I’m using.

require ‘rubygems’  
require ‘mechanize’

agent = Mechanize.new  
page = agent.get(‘[http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do](http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do)’)

search\_form = page.form(‘HPLCDS0101Form’)  
search\_form.callJorEFlg = 1  
search\_form.exeKind = ‘HPLCDS0101E’  
search\_form.searchListCount = 200  
search\_form.checkbox\_with(:value =\> ‘001’).check  
search\_form.checkbox\_with(:value =\> ‘002’).check  
search\_form.checkbox\_with(:value =\> ‘004’).check

page = agent.submit(search\_form)  
pp page

Unfortunately, I’m getting the following error in the request.

C:/Ruby/lib/ruby/gems/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:464:in  
`post_for m': 500 => Net::HTTPInternalServerError (Mechanize::ResponseCodeError) from C:/Ruby/lib/ruby/gems/1.8/gems/mechanize-1.0.0/lib/mechanize.rb:370 :in `submit’  
from tester.txt:15

It looks like I’m missing some parameter in the request object. Can  
anyone suggest what I need to do to make my request work?

Excuse me if I’m doing something wrong, I’m new to this. Thanks!

Hei Robert,

you’re missing a parameter (‘method’) in your form, that’s why the  
POST  
returns 500.  
Here’s your code, modified so that it works:

require ‘rubygems’  
require ‘mechanize’

agent = Mechanize.new  
page = agent.get(‘[http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do](http://www.tse.or.jp/tseHpFront/HPLCDS0101E.do)’)

search\_form = page.form(‘HPLCDS0101Form’)  
search\_form.callJorEFlg = 1  
search\_form[‘method’] = ‘search’  
search\_form.exeKind = ‘HPLCDS0101E’  
search\_form.searchListCount = 200  
search\_form.checkbox\_with(:value =\> ‘001’).check  
search\_form.checkbox\_with(:value =\> ‘002’).check  
search\_form.checkbox\_with(:value =\> ‘004’).check

page = agent.submit(search\_form)  
pp page

hope that helps!
