Question

Still quite new to Python. I have a problem similar to this question. My script is attempting to connect with a web-service that uses wsse on messages and is provisioned using HTTPS. I have to use a non-authenticated proxy. I use suds to use the service as follows:

import logging
import suds
import urllib2
from suds.client import Client
from suds.transport.https import HttpAuthenticated

#---These are not real values but represent them.---------
SERVICE_URL = 'https://service.com/1/soap'
SERVICE_USR = 'serviceusr'
SERVICE_PWD = 'servicepwd'
WSDL_URL = 'file:///folder/a.wsdl'
PROXY_NAME = 'proxy'
PROXY_PORT = 80
#----------------------------------------------------------

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

proxy_info = {'host': PROXY_NAME,'port': PROXY_PORT}
proxyHandler = urllib2.ProxyHandler({'https':'https://(host)s:%(port)d/' % proxy_info})
opener = urllib2.build_opener(proxyHandler)
urllib2.install_opener(opener)
security = suds.wsse.Security()
token = suds.wsse.UsernameToken(SERVICE_USR, SERVICE_PWD)
security.tokens.append(token)
messageTransport = HttpAuthenticated(username = SERVICE_USR, password = SERVICE_PWD)
messageTransport.urlopner = opener
client = Client(url = WSDL_URL, location = SERVICE_URL, transport = messageTransport)
client.set_options(wsse=security)
result = client.service.ParseValidAddress('1 ABC Street Somwhere')

Once the script runs I get the following error:

Error details: <class 'urllib2.URLError'> <urlopen error [Errno -2] Name or service not 
known>

So I ran curl to check all the networking bits are working as follows:

curl -x proxy:80 https://service1.com/1/soap

This returns a SOAP message which indicates the network configuration and proxy are set-up correctly. So why does suds not do the same? Where have I failed?

Answer 1

Success! I did the following and it worked. Added proxySettings = {'https':'http://{0}:{1}'.format(PROXY_NAME, PROXY_PORT)} and then set the option in the client client.set_options(proxy = proxySettings). Thanks to all for help.
