Problems parsing a response using suds
by Håkon Sagehaug
Hi all,
I've been trying to get my sts(WS-Trust) service working with suds, but I've
hit a problem when suds is trying to parse the request. The flow of the
execution is
1. Create a resquest for a security token that looks like this
<SOAP-ENV:Envelope xmlns:wsse="
http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext..."
xmlns:wsu="
http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utilit..."
xmlns:ns0="http://docs.oasis-open.org/ws-sx/ws-trust/200512" xmlns:ns1="
http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="
http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<wsse:Security mustUnderstand="true">
<wsu:Timestamp>
<wsu:Created>2011-06-07T12:24:42.741387Z</wsu:Created>
<wsu:Expires>2011-09-05T12:24:42.741387Z</wsu:Expires>
</wsu:Timestamp>
<wsse:UsernameToken>
<wsse:Username>username</wsse:Username>
<wsse:Password Type="None">password</wsse:Password>
<wsse:Nonce>2a5d2e30b318c1001bb0af853af466bf</wsse:Nonce>
<wsu:Created>2011-06-07T12:24:42.741335Z</wsu:Created>
</wsse:UsernameToken>
</wsse:Security>
</SOAP-ENV:Header>
<ns1:Body>
<ns0:RequestSecurityToken>
<ns0:RequestType>
http://docs.oasis-open.org/ws-sx/ws-trust/200512/Issue</ns0:RequestType>
<ns0:TokenType>
http://docs.oasis-open.org/wss/oasis-wss-saml-token-profile-1.1#SAMLV1.1
</ns0:TokenType>
<ns0:KeyType>
http://docs.oasis-open.org/ws-sx/ws-trust/200512/SymmetricKey</ns0:KeyType>
<ns0:KeySize>256</ns0:KeySize>

http://schemas.xmlsoap.org/ws/2005/02/trust/CK/PSHA1
</ns0:ComputedKeyAlgorithm>
</ns0:RequestSecurityToken>
</ns1:Body>
</SOAP-ENV:Envelope>
This works fine, and when I've got logging on I can see theat the correct
response is coming back from the service. When parsing though, I get this
stacktrace
xxx = client.service.IssueToken(req_type["
http://docs.oasis-open.org/ws-sx/ws-trust/200512/Issue"],tok_type,key_type["
http://docs.oasis-open.org/ws-sx/ws-trust/200512/SymmetricKey
"],key_size,key_alg)
File "/scratch/hakont/python-suds-0.4/suds/client.py", line 542, in

return client.invoke(args, kwargs)

File "/usr/lib64/python2.4/site-packages/_xmlplus/sax/handler.py", line
38, in fatalError
raise exception
xml.sax._exceptions.SAXParseException: <unknown>:1:0: syntax error
I've checked the response, using xmlwf, and it's valid. Have anybody else
experinced this? A similar issue [1] was reported on the forum for 2 years
ago, but not sure if it was solved.
Cheers, Håkon

Doubt about logging implementation
by Bruno Braga
Hi,
Sorry for my ignorance (and if this was already addressed here before), but
I could not find any references to this simple issue...
from suds.client import Client
print Client("http://server/service/?wsdl").service.MyMethod()
Every time I call the client everything works great, but I get a logger
warning:
No handlers could be found for logger "suds.umx.typed"
I read in the README
<http://svn.fedorahosted.org/svn/suds/trunk/README>file that the lib
was changed in a way the user would have to setup this
from outside... I wonder how to deal with this in case I don't want to setup
the logging for it externally.
In my case I am only interested in logging the exception it returns, rather
than internal stuff. I only saw examples for unit testing, which differs
from production code.
If I do something like this:
import logging
logging.basicConfig(level=logging.CRITICAL)
I can get rid of the message, but then it affects my own logging
implementation, unless I use instances of the logger to handle it
separately.
I might be doing something very wrong, but I just couldn't see the answer.
Any help is very appreciated.
Thanks,
--

Multipart replies
by Antti Kaihola
On March 7 2011, Alejandro Blanco Escudero asked on this list:
>I've been using suds lately. The server I'm interacting with is returning

I've updated the patch for suds revision 706 and attached the new
patch to the ticket. I also set up a repository mirror in GitHub and
created a branch in which I keep the patch up-to-date. See my comments
at https://fedorahosted.org/suds/ticket/308 for details.
