Easy way to do a HTTPS POST?

For a business banking app I needed to script out something that would
upload a PGP-encrypted text file through a HTTPS POST command. Since
Ruby is my language of choice for quick hitters like this I looked into
using it for the HTTPS POST part of the puzzle. After googling around
for awhile I didn’t run across anything blatantly obvious as a
solution.

I use the One-Click Installer for Windows version of Ruby 1.8.4 as my
primary development tool. I only saw ‘net/http’ and not ‘net/https’ as
valid choices…

Net::HTTP does the job.
You can see examples on http://www.ruby-doc.org/stdlib/libdoc/net/
http/rdoc/classes/Net/HTTP.html , I’m copypasting here the POST ones:

 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:[email protected]/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

If you need HTTPS make sure to require ‘net/https’ and use something
like this:

 #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'}, ';')
 http = Net::HTTP.new(url.host, url.port)       #  lines
 http.use_ssl = true                            # modified
 res = http.start {|http| http.request(req) }   #  by me
 case res
 when Net::HTTPSuccess, Net::HTTPRedirection
   # OK
 else
   res.error!
 end

I didn’t actually test this code but I think it should work.

By the way, it doesn’t support cookies as far as I know.
In fact I needed a library with which I could interact with a website
that needed a session id stored in a cookie (and not encoded within
the URL) and I wasn’t able to find any. :frowning:

Oops! As soon as I posted, I found an example about using cookies
with Net::HTTP…
Ok, nevermind :slight_smile:

Gotcha. I guess since most of the API docs just had HTTP examples I
assumed that ‘net/http’ didn’t support HTTPS. Since it does this should
be a snap. Thanks for the quick replies!

Try Mechanize. It will handle redirects and cookies for you. It will
also post http/https forms.
