[Fedora-suds-list] Server error, WAS: Re: Suds not using UTF-8 encoding?

[Joshua J. Kugler]

So, here's the debug output:

    soapenv.promotePrefixes()
AttributeError: 'NoneType' object has no attribute 'promotePrefixes'

So, the error is expected given the reply from the server.

Code snippet:

import suds

from suds.transport.https import WindowsHttpAuthenticated

logging.basicConfig(level=logging.CRITICAL)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

ntlm = WindowsHttpAuthenticated(username=r'DOMAIN\user', 
password='****')

c = 
suds.client.Client('file:///home/jkugler/crc/local-tools/services.wsdl',
                       transport=ntlm,
                       headers=headers)

print c.service.GetFolder({'BaseShape':'Default'}, 
{'DistinguishedFolderId':
                                                    {'_Id':'inbox'}})

The example for this call is here:

http://msdn.microsoft.com/en-us/library/aa580274(v=EXCHG.140).aspx

Differences:
Namespace designators...but you declare them in the envelope, so that 
shouldn't be an issue.
"UTF-8" is lower case in the example. *Really* shouldn't matter, but who 
knows.

I also noticed that the SOAPAction in the header is double quoted: that 
is: u'"...."'  Is there a reason for that?

Suds does this:
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

The MS example does this:
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"

I don't have enough knowledge of soap to know if any of these things 
(should) matter.

The other issue I'm having that I alluded to is that the NTLM module (or 
transport) seems to be having major issues with my company's server. 
I'm going to have to found out if they are running 2003 or 2008.  But 
what happens is it just sits there and then finally generates this 
traceback:

    raise urllib2.URLError(err)
urllib2.URLError: <urlopen error [Errno 104] Connection reset by peer>

But, I'm not sure if that's a Suds issue.

Anyway, I'll see what I can do to get around this.
