Porting a pearlescent application to python
I'm trying to port my SOAP communication application in Perl to the Python equivalent at the moment, but can't seem to get past this error it urllib2
throws through suds
. My working soap perl script:
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
-.pm created stubmaker.pl
as part of SOAP::Lite
.
and I installed my python script like this:
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')

return url.open(u2request, timeout=tm)

return self.do_open(httplib.HTTPSConnection, req)

raise URLError(err)
urllib2.URLError: <urlopen error [Errno 8] _ssl.c:490: EOF occurred in violation of protocol>
The client suds
is created well and if I print it out I get a list of expected methods, etc.

It seems, urllib2
can not contact the server. I doubt it urllib2
pays attention to environment variables HTTPS_PKCS12_*
. I assume they are specific to the Perl library you were using, or to Perl itself. urllib2
does not perform SSL certificate validation at all if you want to be better off using pycurl .
These two questions may point you in the right direction:
