SUDS version 0.4 pn x86_64 Python 2.7
I'm having a bear of a time getting HTTP Basic Authentication to work
for a SOAP request via suds. Also using an HTTP proxy server.
In WireShark I just see a request -
GET http://...../services/services/JobService-0.0.1?wsdl HTTP/1.1
Accept-Encoding: identity
Host: .......
Connection: close
User-Agent: Python-urllib/2.7
This doesn't contain any authentication credentials so the response is
HTTP/401, and the client doesn't retry with credentials. The response
does come from the remote as I can see there is a WWW-Authenticate
header and it is from an Apache Tomcat server - so it makes it through
the proxy server.
Code
================
url = 'http://....../services/services/JobService-0.0.1?wsdl'
proxy = urllib2.ProxyHandler({'http': 'http://.....:3128'})
transport = suds.transport.http.HttpAuthenticated()
transport.urlopener = urllib2.build_opener(proxy)
client = suds.client.Client(url, transport=transport,
username='******', password='********')
....
I've tried the above as well as the method described at
<http://blogs.oucs.ox.ac.uk/inapickle/2011/05/14/exchange-web-services-suds-and-python/>
It has the same problem.

When I've got issues like yours, I usually try using a console client
(telnet/curl/wget,...) adding all needed headers/data manually so I'm
totally sure the request is OK, if everything goes Ok you know your
python code need to be reviewed but when you are under proxies you can
find a lot of not python related issues (bad gateways, using proxy when
it shouldn't or vice-versa, requests changed by proxy,....).
wireshark can be very useful but in situations like this I usually
prefer tcpflow output, I think the request/response flow showed is
really useful, but that's a personal preference.
HTH,
bye
