soap4r mapping problem when using google adwords api

P

Patrick Chanezon

The Google Adwords sample that Nahi included in the samples at
http://dev.ctor.org/soap4r/file/trunk/sample/wsdl/googleAdwords/client.rb
does not work.

In the course of fixing it I ran into a roadblock.
Here's my current fix. I highlight the problems I have fixed, and
areas where I'm not very happy with the fix I found.
---
#!/usr/local/bin/ruby

require 'soap/wsdlDriver'
require 'soap/header/simplehandler'

#wsdl =3D 'https://adwords.google.com/api/adwords/v2/CampaignService?WSDL'
wsdl =3D 'CampaignService.wsdl'

class HeaderHandler < SOAP::Header::SimpleHandler
def initialize(tag, value)
super(XSD::QName.new(nil, tag))
@tag =3D tag
@value =3D value
end

#the initial handler from the sample was wrong, it generated 2 level of tag=
s
def on_simple_outbound
@value
end
end

#problem: wsdl2ruby does not pick up soap/property file, so yields a
certificate error when running against this https url
#run it on local file
# To generate deafult.rb, do like this;
# % wsdl2ruby.rb --wsdl
"https://adwords.google.com/api/adwords/v2/CampaignService?WSDL"
--classdef --force
require 'default'

# I don't have an account of AdWords so the following code is not tested.
# Please tell me ([email protected]) if you will get good/bad result in
# communicating with AdWords Server...
drv =3D SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
#problem: http protocol properties set in soap/property from rubyhome
are not picked up
drv.loadproperty('soap/property')
#print drv.options["client"]["ssl_config"].inspect
#problem: wiredump_dev does not output anything when running in SSL mode
drv.wiredump_dev =3D STDOUT
#the file based logger works
drv.wiredump_file_base =3D "log"
drv.headerhandler << HeaderHandler.new('email', '(e-mail address removed)')
drv.headerhandler << HeaderHandler.new('password', 'your_password_here')
drv.headerhandler << HeaderHandler.new('useragent', 'P@ playing with
the API from ruby')
drv.headerhandler << HeaderHandler.new('token', 'your_token_here')
camplist =3D drv.call("getAllAdWordsCampaigns", GetAllAdWordsCampaigns.new(=
123))
print camplist
---

When I run that with a valid adwords developer account, the call is
made and the correct repsonse is sent back, as seen in the filke log.
However the mapper barfs.

I incldue the relevant data.
Any idea of where to look for next is welcome.
I run soap4r soap4r-1_5_4, which seem to have fixed a few things
regarding doc/literal encoding style.

How is this registry informed about the classes that must be used for
mapping when using the wsdl files?
Is there a message to be sent to drv in order to let it know about
default.rb classes?

A few hours later after finding this other sample
I now generate the client driver myself using wsdl2ruby
wsdl2ruby.rb --wsdl CampaignService.wsdl --type client

Now I understand where the mapping is defined.
Still the new program yields the same error

It is as if the mapping defined in CampaignService is not used.

Thanks in advance for any hints.

adding some debug in proxy.rb
def response_doc_lit(body, mapping_registry)
puts "in proxy mapping =3D #{mapping_registry.inspect}"
body.collect { |key, value|
Mapping.soap2obj(value, mapping_registry)

end

shows that the mapping does not contain any information about the adwords t=

Is the init generated by wsdl2ruby correct?
if RUBY_VERSION > "1.7.0"
def add_method_interface(name, param_count)
::SOAP::Mapping.define_singleton_method(self, name) do |*arg|
unless arg.size =3D=3D param_count
raise ArgumentError.new(
"wrong number of arguments (#{arg.size} for #{param_count})")
end
call(name, *arg)
end
self.method(name)
end

The Google Adwords sample that Nahi included in the samples at
http://dev.ctor.org/soap4r/file/trunk/sample/wsdl/googleAdwords/client.rb
does not work.
=20
In the course of fixing it I ran into a roadblock.
Here's my current fix. I highlight the problems I have fixed, and
areas where I'm not very happy with the fix I found.

When I run that with a valid adwords developer account, the call is
made and the correct repsonse is sent back, as seen in the filke log.
However the mapper barfs.
=20
I incldue the relevant data.
Any idea of where to look for next is welcome.
I run soap4r soap4r-1_5_4, which seem to have fixed a few things
regarding doc/literal encoding style.

How is this registry informed about the classes that must be used for
mapping when using the wsdl files?
Is there a message to be sent to drv in order to let it know about
default.rb classes?
=20
A few hours later after finding this other sample
I now generate the client driver myself using wsdl2ruby
wsdl2ruby.rb --wsdl CampaignService.wsdl --type client
=20
Now I understand where the mapping is defined.
Still the new program yields the same error
