[LRUG] submitting a form programatically

[Dan Webb]

Hi Ed,

Net::HTTP::Post is what you are after:

require 'net/http'
    require 'uri'

    #1: Simple POST
    res = Net::HTTP.post_form(URI.parse('http://www.example.com/search.cgi'),
                              {'q'=>'ruby', 'max'=>'50'})
    puts res.body

    #2: POST with basic authentication
    res = Net::HTTP.post_form(URI.parse('http://jack:pass@www.example.com/todo.cgi'),
                                        {'from'=>'2005-01-01',
'to'=>'2005-03-31'})
    puts res.body

    #3: Detailed control
    url = URI.parse('http://www.example.com/todo.cgi')
    req = Net::HTTP::Post.new(url.path)
    req.basic_auth 'jack', 'pass'
    req.set_form_data({'from'=>'2005-01-01', 'to'=>'2005-03-31'}, ';')
    res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req) }
    case res
    when Net::HTTPSuccess, Net::HTTPRedirection
      # OK
    else
      res.error!
    end

Cheers,

Dan
