net/http broken?

[tsuraan]

The documentation for net/http on ruby-doc.org gives the following
snippet for getting data from a server using HTTP POST:

require 'net/http'
require 'uri'

res =3D Net::HTTP.post_form(URI.parse('http://www.example.com/search.cg=
i'),
{'q'=3D>'ruby', 'max'=3D>'50'})
puts res.body

The problem with this is that in ruby 1.8.2 on both my OSX box and my
FreeBSD computer, Net::HTTP does not have a post_form defined. So,
that example doesn't work. Another way of doing the same idea, given
by ruby-doc.org, is:

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

This has the problem that req has no set_form_data method. So, does
anyone know what's going wrong? Is it possible to use the ruby
standard libraries to post data to a server?

Hm, 1.8.3 has it:

17:02:52 [~]: ruby -r net/http -e 'p RUBY_VERSION; p
Net::HTTP.public_methods.grep /post/i'
-e:1: warning: parenthesize argument(s) for future version
"1.8.3"
["post_form"]

This is on cygwin. I wouldn't assume that post_form was removed in 1.8.2
and added in 1.8.3. Are you sure the method is not present? (You can
test with the same code snippet.)

Kind regards

end

Seems the docs are wrong. I had the same problem not too long ago.

Here's an example of what works for me:

require 'net/http'

# post some data to uriort/page

uri = 'www.example.com'
port = 80
page = '/RPC/foo'
data = '<foo><bar>Doodle!</bar></foo>'

Net::HTTP.start( uri, port) { |http|
results = http.post( page, data )
}

Hm, 1.8.3 has it:

17:02:52 [~]: ruby -r net/http -e 'p RUBY_VERSION; p
Net::HTTP.public_methods.grep /post/i'
-e:1: warning: parenthesize argument(s) for future version
"1.8.3"
["post_form"]

Hm, I get just "1.8.2" when I run that. Same thing on my apple and my
freebsd box. Strange...

Net::HTTP.start( uri, port) { |http|
results =3D http.post( page, data )
}

I'll give that a shot. Thanks!

Ah. That explains my problem using the Windows installer version.
There has been no 1.8.3 release, for assorted reasons, and I forgot that
I'm therefore not running the latest Ruby.

So my suggestion is a 1.8.2 bit of code.

I believe Curt will release a 1.8.4 Windows installer version when Matz
releases that version of Ruby around Christmas.

[...] you just need to either use a more recent Ruby, or [...]

I'd be tempted to just scoop http.rb, https.rb & protocol.rb out of:
http://www.ruby-lang.org/cgi-bin/cvsweb.cgi/ruby/lib/net/?only_with_tag=v1_8_3
into a new directory and prepend to $:
