Form Filler

[eastcoastcoder]

Is there an equivalent in Ruby to the Perl modules which can "fill out
an html/http form"?

Given a hash, I'd like to either get the query string to append to the
URL for GET's, or the POST contents to append for POST's, as if the
hash was the form[field] = value. The routine should handle the url
encoding and the like.

Any luck?
(If not, anyone up for a quick few lines of Ruby ninjahood?)

Ara's time machine is almost as good as Guido's time machine, it seems.

Oh, and someone apparently hacked up a Ruby WWW::Mechanize which is suppose=
d=20
to do this.

Excellent, most appreciated.

Forgive my RFC ignorance, but is the same string appended to the URL
for GETs and sent as the bod for POST's? Or is there a difference in
the encoding somehow?

it certainly is different. google around for more info. you'll need to use
something like http-access2 for posting form data. check out my rubyforge
script (on rubyforge no less) for a pretty complete example of posting
including file uploads and redirects.
