How can I output what SUDs is generating/receiving?

Solution 1:

SUDS provides some convenience methods to do just that:

 client.last_sent()
 client.last_received()

These should provide you with what you need. I use them for error logging. The API doc for Client class should have any extra info you need.

Solution 2:

You can use the MessagePlugin to do this (this will work on the newer Jurko fork where last_sent and last_received have been removed)

from suds.plugin import MessagePlugin

class LogPlugin(MessagePlugin):
  def sending(self, context):
    print(str(context.envelope))
  def received(self, context):
    print(str(context.reply))

client = Client("http://localhost/wsdl.wsdl", plugins=[LogPlugin()])

Solution 3:

Suds supports internal logging, as you have been doing.

I am setting info levels like you:

logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG) # MUST BE THIS?
logging.getLogger('suds.xsd.schema').setLevel(logging.DEBUG)
logging.getLogger('suds.wsdl').setLevel(logging.DEBUG)
logging.getLogger('suds.resolver').setLevel(logging.DEBUG)
logging.getLogger('suds.xsd.query').setLevel(logging.DEBUG)
logging.getLogger('suds.xsd.basic').setLevel(logging.DEBUG)
logging.getLogger('suds.binding.marshaller').setLevel(logging.DEBUG)

And I also sometimes need to override the root logger logging level, depending on the framework being used under Suds calls (Django, Plone). If the root logger has a higher logging threshold, log messaegs may never appear (not sure how logger hierarchies should go). Below is an example how to override:

def enableDebugLog(self):
    """ Enable context.plone_log() output from Python scripts """
    import sys, logging
    logger = logging.getLogger()        
    logger.root.setLevel(logging.DEBUG)
    logger.root.addHandler(logging.StreamHandler(sys.stdout))

Solution 4:

To get only the generated message this also works:

from suds.client import Client
import sys

SB_PRIVATE_ACCESS = {"PATH":"https://thisurl.com:443/services/",}

client = Client(SB_PRIVATE_ACCESS['PATH'])

client.set_options(nosend=True)

resp = ...<invoke client here>...

sys.stdout.buffer.write(resp.envelope)
