How to log raw XML requests and responses in Suds

Suppose you are using Suds and you want to log every raw XML request and response to a SOAP service. This can be useful to debug an integration with a SOAP web service.

You can write a MessagePlugin class for this, and use it in the construction of your client.

import logging
from xml.dom.minidom import parseString
from suds.client import Client
from suds.plugin import MessagePlugin

logger = logging.getLogger(__name__)

class SudsLoggerPlugin(MessagePlugin):

    def pretty_log(self, xml_content):
        try:
            dom = parseString(xml_content)
            logger.debug(dom.toprettyxml())
        except:
            logger.exception('Cannot log XML')

    def sending(self, context):
        self.pretty_log(context.envelope)

    def received(self, context):
        self.pretty_log(context.reply)

client = Client('your/wsdl/path/here?wsdl',
    plugins=[ SudsLoggerPlugin() ])
