How can I output what SUDs is generating/receiving?

问题

I have the following code:

from suds.client import Client
import logging

logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)
logging.getLogger('suds.transport').setLevel(logging.DEBUG)
logging.getLogger('suds.xsd.schema').setLevel(logging.DEBUG)
logging.getLogger('suds.wsdl').setLevel(logging.DEBUG)

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

client = Client(SB_PRIVATE_ACCESS['PATH'])
print client

but I am getting 500 errors. I am trying to send what XML is being generated and received through SUDs, to the wsdl developer, but I can't figure how to output it? I have been looking in the documentation of SUDs, but can't seem to find it :/ Does anyone know how to output the raw xml that is sent and received?

回答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.

回答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()])

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))

回答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)

try changing

logging.basicConfig(level=logging.INFO)

logging.basicConfig(filename="/tmp/suds.log", level=logging.DEBUG)

回答6:

If you want to reduce logging by jurko-suds

 logging.basicConfig(level=logging.INFO)

    logging.getLogger('suds.client').setLevel(logging.INFO)
    logging.getLogger('suds.transport').setLevel(logging.INFO) 
    logging.getLogger('suds.xsd.schema').setLevel(logging.INFO)
    logging.getLogger('suds.wsdl').setLevel(logging.INFO)
    logging.getLogger('suds.resolver').setLevel(logging.INFO)
    logging.getLogger('suds.xsd.query').setLevel(logging.INFO)
    logging.getLogger('suds.xsd.sxbasic').setLevel(logging.INFO)
    logging.getLogger('suds.xsd.sxbase').setLevel(logging.INFO)
    logging.getLogger('suds.metrics').setLevel(logging.INFO)
    logging.getLogger('suds.binding.marshaller').setLevel(logging.INFO)

I have hit this problem working with the bingads API, worth noting the order is important I had to import logging then import suds start the logging then import bingads, any other order and nothing was output in the logs from suds.

So check your import order, and move your logging statements and it may fix your issue.
