I'm trying to do a POST using net/http.

When I do:

r = Net::HTTP.post_form(u,{'volumectrl'=>'-20'})

I get:

NoMethodError: undefined method `post_form' for Net::HTTP:Class
        from (irb):5

What am I doing wrong?

Thanks!

What ruby version are you running? I ran into this same problem last
week, and it was because the standard stdlib documentation (on ruby-doc)
refers to ruby 1.9, where the post_form method exists. It doesn't exist
in ruby 1.8. Annoying huh?

Try something like:

      Net::HTTP.start('www.foo.com', 80) do | http |
        response = http.post('/cgi-bin/foo.cgi', encoded_post)
     end

Note that you'll need to manually turn your hash into a URI-encoded
string. Look at URI.encode() in the stdlib.

It exists in 1.8.3, it would seem:

[Prospero:~] matt% ruby -v
ruby 1.8.3 (2005-09-21) [powerpc-darwin8.3.0]
[Prospero:~] matt% ruby
require 'net/http'
puts Net::HTTP.methods.include?("post_form")
true

I've used it with no problems at all, in the same basic format as the
original poster.
