Web Services problem: OpenSSL::X509::StoreError

Hi,

I have a Ruby script that invokes web services using SSL. It works.

In order to make my web service work over https (SSL) i had to :
_create a directory called “soap” in my working directory.
_create a file in that dir called property that contains :
client.protocol.http.ssl_config.ca_file = ca.pem
_add ca.pem in my working directory that contains my certificates.

So here is what I have in my working dir:
_client.rb
_soap
_soap/property
_ca.pem

The problem is when I try to integrate it in my Ruby on Rails
application I
have the error in my controller:

OpenSSL::X509::StoreError in Air searchController#search_trip

RAILS_ROOT: D:/www/airtravelonrails/config/…

-e:3

So when I look closer in the file http-access2 line 532 we see that the
problem comes from the function:

def set_trust_ca(trust_ca_file_or_hashed_dir)
if FileTest.directory?(trust_ca_file_or_hashed_dir)
@cert_store.add_path(trust_ca_file_or_hashed_dir)
else
@cert_store.add_file(trust_ca_file_or_hashed_dir)
end
change_notify
end

from the line @cert_store.add_file(trust_ca_file_or_hashed_dir)

Is anybody knows how to use SSL Web Services in a Rails application?

Thank you.

Can you change above “ca.pem” to fully qualified pathname such as
“D:/path/to/ca.pem” and see how it goes?

So I have changed the path to the ca.pem file. I have an other error.
Let me
explain.
My problem is when I try to integrate it in my Rails application I have
an
argument error:
ArgumentError in Air searchController#rt_results

wrong number of arguments (1 for 0)

RAILS_ROOT: D:/www/airtravelonrails/config/…

Which is weird. If I don’t pass any argument I have the error "wrong
number
of arguments (0 for 1) "…

Here is my controller:

require ‘soap/header/handler’
require ‘http-access2’
require ‘soap/wsdlDriver’

class AirSearchController < ApplicationController

before_filter :check_authentication

layout “layout”

def index

end

def airports_for_lookup
@airports = Airport.find(:all)
@headers[‘content-type’] = ‘text/javascript’
render :layout => false
end

class EmptyHeaderHandler < SOAP::Header::Handler
def on_outbound(header)
# dump SOAPHeader even if it has no item
header.force_encode = true
header.extraattr[‘xmlns’] =
http://webservices.site.com/definitions
# no item needed
nil
end
end

def rt_results

wsdl = "D:/www/airtravelonrails/app/controllers/myWsdl.wsdl"

factory = SOAP::WSDLDriverFactory.new(wsdl)
driver = factory.create_rpc_driver

driver.headerhandler << EmptyHeaderHandler.new(XSD::QName::EMPTY)

parameters = {
:messageActionDetails => { :functionDetails => { :actionCode => “***”
} },

:originatorDetails => [{ :deliveringSystem => [
:companyIdentification => “",
:locationCode
=>
"
” ],
:originatorIdentification => [ :travelAgent
=>
",
:inHouseId =>
"
”],

                       :agentDetail =>              [ 

:isoCountryCode =>

:isoCurrencyCode

"

:isoLanguageCode

*”],

                       :authorityCode => "*****" }],

:requestSection => [{
:availabilityProductInfo =>

                       # etc 

req = driver.Air_MultiAvailability(parameters)

end

end

I don’t know how to make a correct call to my web service…

Thank you.

  1. Can you show me the error dump of ‘arguments (0 for 1)’ as same as
    above, please? You get the same stack trace?

  2. WSDLDrverFactory#create_rpc_driver parses WSDL every time you call
    it and it’s heavy process. Please consider to use wsdl2ruby.rb or, call
    WSDLDriverFactory#create_rpc_driver only once and reuse the driver.

  2. I have a different error, here is the application stack trace:

OK.

  1. I have a different error, here is the application stack trace:

ArgumentError in Air searchController#rt_results
wrong number of arguments (0 for 1)

(eval):4:in air_MultiAvailability' C:/ruby/lib/ruby/1.8/soap/wsdlDriver.rb:117:insend
C:/ruby/lib/ruby/1.8/soap/wsdlDriver.rb:117:in `Air_MultiAvailability’

It’s normal. You need to pass one argument then. (BTW, you can call
driver.air_MultiAvailability instead of driver.Air_MultiAvailability.
Soap4r converts a method name to Ruby compliant safer name and add a
wrapper method for an original name as above)

So the actual problem is ‘wrong number of arguments (1 for 0)’ raised
from lib/active_support/core_ext/array/conversions.rb:66:in `to_xml’. I
can’t imagine why it’s called but a method name ‘to_xml’ is suspicious.
Two-ducks-close-but-not-the-same problem.

Please post a full stack trace of ‘wrong number of arguments (1 for 0)’?

Hi,

I updated soap4r gem as 1.5.6-RC3.
You can get it from
http://dev.ctor.org/soap4r/wiki/WikiStart#a2007-06-07:1.5.6-RC3 .
Would you please try the latest release candidate?

Anyway, I’m still on the problem, I don’t understand what it could be, here
is the full stack trace:

Thanks. I found that generic Array has to_xml instance method in Rails
environment. The method requires Array’s elements to have to_xml method
with arity == 1 if it responds to to_xml. On the other hand, soap4r
requires Objects to have to_xml method with arity == 0 if it responds to
to_xml.

I just renamed the method name to_xml to to_xmlpart in soap4r. This new
feature is from soap4r-1.5.6 which is scheduled to be released on
2007-06-14.

Ok, I have updated soap4r.
I wait for your next release (june 14th) so I could test again if my web
service works.

Thank you for your help and responsiveness.
Thanks for mentioning my name on your site.

Well I knew it was not the same problem, I’ve tried no argument just
like
that to test what was happening.
