Nuby Http question

I am a Ruby Nuby and am seeking some assistance.

I am trying to write a small program to download some historical end of day
stack data.

Using a browser, the URL would be:
http://fs.tradingroom.com.au/tpl/investments/tr_cur_price_hist_csv.isam?code
=CVS

The program I’m using is an example from the net/http.rb:

require ‘net/http’

http = Net::HTTP.new(‘fs.tradingroom.com.au’, 80)

using block

puts "Opening file: testCVS.csv"
File.open( ‘testCVS.csv’, ‘w’ ) {|f|
http.post( ‘/tpl/investments/tr_cur_price_hist_csv.isam’,
‘query=subject&code=CVS’ ) do |str|
f.write str
end
}

Unfortunately this program only returns the first line of the file, which is
only the headings. Could show me how I can get the rest of the file?

Thanks,
Ot Ratsaphong

    http.post( '/tpl/investments/tr_cur_price_hist_csv.isam',
'query=subject&code=CVS' ) do |str|

You don't use the same URL, just write

   http.post( '/tpl/investments/tr_cur_price_hist_csv.isam', 'code=CVS')

Unfortunately this program only returns the first line of the file, which is
only the headings. Could show me how I can get the rest of the file?

This is because you have added 'query=subject' to your URL
