Hi all,
I'm still quite new to Ruby, I come from years of "evil" development (MS
and .NET).
I am using ruby1.9.1 and soap4r to communicate with a .NET web service.
I've seen several posts, several advices, several "solutions"; I tried
them all, and still it doesn't work...
I've been trying different approaches for a couple of days now, and I
feel I am getting stuck.
My dumb web service is here: http://78.136.25.213/Test/ws/Service.asmx
From here you can get its WSDL:
http://78.136.25.213/Test/ws/Service.asmx?wsdl
It's a basic ws that expects a single string parameter ("inputString")
as input and returns a single string as output. That simple (this is a
test of course).
This is the code of my client:
···
-------------------------------------------------------------------------------
require "soap/rpc/driver"
require "RechnerServiceModule"
include RechnerServiceModule
server = 'http://78.136.25.213/Test/ws/Service.asmx'
wiredump_dev=STDERR
service = SOAP::RPC::Driver.new(server,
RechnerServiceModule::InterfaceNS)
service.use_default_namespace = true
service.default_encodingstyle =
SOAP::EncodingStyle::ASPDotNetHandler::Namespace
service.wiredump_dev=wiredump_dev
RechnerServiceModule::add_method(service)
result = service.TestWS(:parameter => "testString")
print("Result: ", result)
-------------------------------------------------------------------------------
This is the RechnerServiceModule:
-------------------------------------------------------------------------------
###file:servicemodule.rb
module RechnerServiceModule
InterfaceNS = 'http://tempuri.org/TestWS'
Methods=[['TestWS', 'inputString']]
def RechnerServiceModule.add_method(drv)
Methods.each do |method, *param|
drv.add_method_with_soapaction(method, InterfaceNS, *param)
end
end
end
-------------------------------------------------------------------------------
Looking at the wiredump I see that this is the SOAP XML sent (which
apparently is identical to the one .NET expects - on the TestWS web
page: http://78.136.25.213/Test/ws/Service.asmx?op=TestWS):
-------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8" ?><soap:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Body>
<TestWS xmlns="http://tempuri.org/TestWS">
<inputString>testString</inputString> </TestWS>
</soap:Body></soap:Envelope>
-------------------------------------------------------------------------------
Unfortunately I keep on receiving an error, as you can see in the
response:
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
I tried the approach of generating the WSDL proxy, and this is the error
I received:
-------------------------------------------------------------------------------

-------------------------------------------------------------------------------
So, if anybody has the solution to this, I would really love to hear
that, since this is killing me now...
Thanks for the help!
