SOAP Ruby On Rails logon Affili.net - ruby-on-rails

Question

I try to logon Affili.net via SOAP by using the savon-gem.
client = Savon.client do
wsdl "https://api.affili.net/V2.0/Logon.svc?wsdl"
end
message = {
'Username' => '123123',
'Password' => '123123',
'ins2:WebServiceType' => 'Publisher' }
response = client.call(:logon, :message => message)
But I only get this exception:
(a:DeserializationFailed) The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://affilinet.framework.webservices/Svc:LogonRequestMsg. The InnerException message was 'Error in line 1 position 777. 'EndElement' 'LogonRequestMsg' from namespace 'http://affilinet.framework.webservices/Svc' is not expected. Expecting element 'Username | Password | WebServiceType'.'. Please see InnerException for more details.
https://developer-api.affili.net/V2.0/Logon.svc?wsdl
Whats wrong?
Update
Now i tried some tools like this:
http://www.soapclient.com/soapclient?template=%2Fclientform.html&fn=soapform&SoapTemplate=%2FSoapResult.html&SoapWSDL=https%3A%2F%2Fdeveloper-api.affili.net%2FV2.0%2FLogon.svc%3Fwsdl&_ArraySize=2
And it also tells me: it does not work. But my Account and that credentials are ok!
So I tried it on PHP
define ("WSDL_LOGON", "https://api.affili.net/V2.0/Logon.svc?wsdl");
define ("WSDL_STATS", "https://api.affili.net/V2.0/PublisherStatistics.svc?wsdl");
$Username = '123123'; // the publisher ID
$Password = '123123'; // the publisher web services password
$SOAP_LOGON = new SoapClient(WSDL_LOGON);
$Token = $SOAP_LOGON->Logon(array(
'Username' => $Username,
'Password' => $Password,
'WebServiceType' => 'Publisher'
));
echo $Token;
and it works!
Whats the difference between all online tools, all offline tools and Ruby on Rails and PHP?

Answer 1

Try to send message with symbolized keys, like this:
message = {
logon: {
username: '123123',
password: '123123',
web_service_type: 'Publisher'
}
}

Answer 2

I still do not know the difference between the savon (2.7.2) and the PHP implementation.
But there is a solution for affili.net by using savon 3 (but it is not stable yet!)
client = Savon.new("https://api.affili.net/V2.0/Logon.svc?wsdl")
logon_body = {
LogonRequestMsg: {
'Username' => '123123',
'Password' => '123123',
'WebServiceType' => 'Publisher'
}
}
operation = client.operation('Authentication', 'DefaultEndpointLogon', 'Logon')
operation.body = logon_body
response = operation.call
puts response.body[:credential_token]
