Porting perl soap application to python

I'm trying to port my Perl SOAP communication application to a Python equivalent at the moment but can't seem to get past this error that urllib2 is throwing via suds. My working perl soap script is:

use myStub;
$ENV{HTTPS_PKCS12_FILE} = '/path/to/certificate';
$ENV{HTTPS_PKCS12_PASSWORD} = 'password';
my $client = new myStub;
my $output = $client->foo('test', 'something');
print $output

where myStub is the .pm created by stubmaker.pl as part of SOAP::Lite.

and I set up my python script as follows:

from suds.client import Client
import os

os.environ['HTTPS_PKCS12_FILE'] = '/path/to/certificate'
os.environ['HTTPS_PKCS12_PASSWORD'] = 'password'
client = Client('file:WSDL')
output = client.service.foo('test', 'something')
print output

which gives me:

File "test.py", line 12, in <module>
    output = client.service.foo('test', 'something')
  File "/usr/lib/python2.6/site-packages/suds/client.py", line 542, in __call__
    return client.invoke(args, kwargs)
  File "/usr/lib/python2.6/site-packages/suds/client.py", line 602, in invoke
    result = self.send(soapenv)
  File "/usr/lib/python2.6/site-packages/suds/client.py", line 643, in send
    reply = transport.send(request)
  File "/usr/lib/python2.6/site-packages/suds/transport/https.py", line 64, in send
    return  HttpTransport.send(self, request)
  File "/usr/lib/python2.6/site-packages/suds/transport/http.py", line 77, in send
    fp = self.u2open(u2request)
  File "/usr/lib/python2.6/site-packages/suds/transport/http.py", line 118, in u2open
    return url.open(u2request, timeout=tm)
  File "/usr/lib64/python2.6/urllib2.py", line 391, in open
    response = self._open(req, data)
  File "/usr/lib64/python2.6/urllib2.py", line 409, in _open
    '_open', req)
  File "/usr/lib64/python2.6/urllib2.py", line 369, in _call_chain
    result = func(*args)
  File "/usr/lib64/python2.6/urllib2.py", line 1198, in https_open
    return self.do_open(httplib.HTTPSConnection, req)
  File "/usr/lib64/python2.6/urllib2.py", line 1165, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno 8] _ssl.c:490: EOF occurred in violation of protocol>

The suds client is getting created fine and if I print it out, I get the expected methods being listed etc.

Looks like urllib2 is unable to communicate with the server. I doubt urllib2 is paying any attention to the HTTPS_PKCS12_* environment variables. My guess would be that those are specific to the Perl library you were using, or to Perl itself. urllib2 doesn't do any SSL cert validation at all, if you want that you're better off using pycurl.

These two questions might point you in the right direction:
