Python suds “RuntimeError: maximum recursion depth exceeded while calling a Python object”

Question

I\'m trying to consume a SOAP web service using Python suds but I am getting the error \"RuntimeError: maximum recursion depth exceeded while calling a Python object\".

Answer 1

After more testing, it seems that (unfortunately) suds has trouble interpreting Java Collection objects serialized as XML. I ended up using SOAPpy instead to avoid this issue. If someone can suggest a fix, that would be awesome! I really like suds for its other merits over SOAPpy.

Answer 2

I tried lots of SUDS versions and forks, and finally got to find one that works with proxies, https and authenticated services, find it here:

Also, here is example code showing simple usage:

from suds.client import Client

# SOAP WSDL url
url = 'https://example.com/ws/service?WSDL'

# SOAP service username and password for authentication, if needed
username = 'user_name'
password = 'pass_word'

# local intranet proxy definition to get to the internet, if needed
proxy = dict(http='http://username:password@localproxy:8080',
             https='http://username:password@localproxy:8080')

# unauthenticaded, no-proxy
# client = Client(url)

# use a proxy to connect to the service
# client = Client(url, proxy=proxy)

# no proxy, authenticathed service
# client = Client(url, username=username, password=password)

# use a proxy to connect to an authenticated service
client = Client(url, proxy=proxy, username=username, password=password)

print client
