For example in the online API ( or using 'ri Net::HTTP#post' ) : QUOTE post(path, data, initheader = nil, dest = nil) {\|+body_segment+\| ...} Posts data (must be a String) to path. header must be a Hash like { ‘Accept’ => ’/’, … }. In version 1.1 (ruby 1.6), this method returns a pair of objects, a Net::HTTPResponse object and an entity body string. In version 1.2 (ruby 1.8), this method returns a Net::HTTPResponse object. If called with a block, yields each fragment of the entity body in turn as a string as it are read from the socket. Note that in this case, the returned response object will not contain a (meaningful) body. dest argument is obsolete. It still works but you must not use it. In version 1.1, this method might raise an exception for 3xx (redirect). In this case you can get an HTTPResponse object by "anException.response". In version 1.2, this method never raises exception.

New D.I.C Head Joined: 9 Oct, 2008 Posts: 8	i am making a program that will read a text file (this part is done), then input that data on to a form (looks like a table) on the internet. currently you have to enter your numbers manually on to the form, choose a radio button, and then press the OK button. next the web page takes this data and shows it to you to confirm. then you press OK again. that is basically what i am trying to automate. my problem is that I really do not know how to enter data on to a webpage. I can make a program to read the data, I just don't know how to write the data.

If you want to post data to a form you might look at Mechanize :

Example using Mechanize to query Google :

ruby

Google
  require 'rubygems'
  require 'mechanize'

  a = WWW::Mechanize.new { |agent|
    agent.user_agent_alias = 'Mac Safari'
  }

  a.get('http://google.com/') do |page|
    search_result = page.form_with(:name => 'f') do |search|
      search.q = 'Hello world'
    end.submit

    search_result.links.each do |link|
      puts link.text
    end
  end
