Net::HTTP working on Windows, but not Unix


#1

We have an odd problem at work today.

Running the following code on Windows XP gives us a CVV2 error, which
is what we expect (we didn’t give one). However, running the same
code on Linux or OS X gets a complaint that we didn’t provide the
key, which is obviously not true (see last line).

Does anyone see anything inherently non-portable in the following code?

require ‘net/http’
require ‘net/https’

uri = URI.parse ‘https://www.usaepay.com/gate.php
p (http = Net::HTTP.new(uri.host, uri.port))
p http.use_ssl = true
p http.verify_mode = OpenSSL::SSL::VERIFY_NONE
p http.post(uri.path, “UMkey=OUR_KEY_CODE_HERE”).body

Thanks in advance for any hints.

Switching the code to the following seems to work everywhere, as long
as 1.8.4 is used:

require ‘net/https’

uri = URI.parse ‘https://www.usaepay.com/gate.php
req = Net::HTTP::Post.new(uri.path)
req.set_form_data “UMkey” => “OUR_KEY_CODE_HERE”
p (http = Net::HTTP.new(uri.host, uri.port))
p http.use_ssl = true
p http.verify_mode = OpenSSL::SSL::VERIFY_NONE
p http.start { http.request(req) }.body

I still don’t understand why the first version didn’t work though…

Sorry to keep responding to myself but we have now realized that that
the Windows machine, where the top example originally worked, was
running 1.8.2 while both failing machines were running 1.8.4.

The bottom “fix” did not work on the Windows box right off the bat,
because set_form_data() seems to have been added after 1.8.2.
Upgrading fixes the issue.

That raises the question of what caused the original failure though.
Was the handling of the second parameter to post() changed between
1.8.2 and 1.8.4? If so, I suspect there could be some more broken
code out there…

Awesome. Thank you so much.

There must be a bug in 1.8.4 Net::HTTP post.
I suspect lib/net/http.rb line #1507

 unless content_type()
   warn 'net/http: warning: Content-Type did not set; using  

application/x-www-form-urlencoded’ if $VERBOSE
set_content_type ‘application/x-www-form-urlencoded’
end

Hmm, I’ll move this over to Ruby Core now and see if we can get the
people in-the-know looking into this…

Hi,

We have an odd problem at work today.

uri = URI.parse ‘https://www.usaepay.com/gate.php
p (http = Net::HTTP.new(uri.host, uri.port))
p http.use_ssl = true
p http.verify_mode = OpenSSL::SSL::VERIFY_NONE
p http.post(uri.path, “UMkey=OUR_KEY_CODE_HERE”).body
This will work :

p http.post(uri.path, “UMkey=OUR_KEY_CODE_HERE”,{‘Content-Type’ =>
‘application/x-www-form-urlencoded’}).body

Switching the code to the following seems to work everywhere, as long as
1.8.4 is used:
