SOAP4R newbie question

ruby-talk
1

Just started playing with SOAP4R and its very cool.

I’m trying to access a service that requires users to logon before doing
stuff, my first effort was as follows:

require ‘soap/rpc/driver’

base = ‘http://foo.bar.com/services/’

logon_service = SOAP::RPC::Driver.new(base + ‘LogonService?wsdl’, nil)
logon_service.add_method(‘login’, ‘username’, ‘password’)
logon_service.login(‘foo’, ‘bar’)

do_stuff_service = SOAP::RPC::Driver.new(base + ‘DoStuffService?wsdl’, nil)
do_stuff_service.add_method(‘getThing’)
do_stuff_service.getThing()

This logs in to the first service okay, but calls to DoStuffService fail
with ‘not logged in’. I assume this is because the login/session details
are maintained by cookies and so I need to invoke both services from the
same driver.

Something like:

single_service = SOAP::RPC::Driver.new(base, nil)
single_service.add_method(‘login’, ‘username’, ‘password’)
Single_service.add_method(‘getThing’)

I just cant figure out how to tell each method to use which service (i.e…
namespace) …

Should I be using add_method_with_soapaction? Or is it restricted to one
service/namespace per driver?

I’m trying to access a service that requires users to logon before doing

base = ‘http://foo.bar.com/services/’

logon_service = SOAP::RPC::Driver.new(base + ‘LogonService?wsdl’, nil)

do_stuff_service = SOAP::RPC::Driver.new(base + ‘DoStuffService?wsdl’, nil)
do_stuff_service.add_method(‘getThing’)
do_stuff_service.getThing()

This logs in to the first service okay, but calls to DoStuffService fail
with ‘not logged in’. I assume this is because the login/session details
are maintained by cookies and so I need to invoke both services from the
same driver.

Isn’t the service a kind of “logging-in with user/passwd to get a session
token then passing the token with all methods”, is it?

When the service uses http-cookies as you mention, you must use http-access2
instead of net/http (net/http does not support http-cookies as a first class),
and must call some internal method (not out-of-box support for now).

What version are you using?

  1. ruby/1.8.1 + bundled soap module
  2. ruby/CVS HEAD + bundled soap module
  3. soap4r/1.5.2
  4. soap4r/CVS HEAD

I just cant figure out how to tell each method to use which service (i.e…
namespace) …

Should I be using add_method_with_soapaction?

Yes. Or simply create a new driver.
