How to pass SOAP headers into python SUDS that are not defined in WSDL file

I have worked out how to enter in new headers and namespaces in suds.As stated above you create an Element and pass it in as a soapheader as so:

from suds.sax.element import Element client = client(url) ssnns = ('ssn', 'http://namespaces/sessionid') ssn = Element('SessionID', ns=ssnns).setText('123') client.set_options(soapheaders=ssn)  result = client.service.addPerson(person)

But if you would like to add a namespace I have found adding a prefix seem's to do the trick. So when you create one of the elements you add addPrefix. I'm not sure if this was the way it was intended to be done but it work's.

ssn = Element('SessionID', ns=ssnns).setText('123').addPrefix(p='SOAP-ENC', u='http://www.w3.org/2003/05/soap-encoding')

The p = 'SOAP-ENC' can be any prefix eg. wsa and the u = http://address is the address of the namespace.

A complete script that would run could be:

#!/usr/local/bin/python2.6import suds#import loggingfrom suds.client import Clientfrom suds.sax.element import Elementfrom suds.sax.attribute import Attributefrom suds.xsd.sxbasic import Importdef absoluteMove():    # connects to WSDL file and stores location in variable 'client'    client = Client('http://10.10.10.10/p.wsdl')    client.options.location = 'http://10.10.10.10:32963'    # Create the header    wsans = ('wsa', 'http://schemas.xmlsoap.org/ws/2004/08/addressing')    mustAttribute = Attribute('SOAP-ENV:mustUnderstand', 'true')    n1s = ('SOAP-ENC', 'http://www.w3.org/2003/05/soap-encoding')    msgId = Element('Element').addPrefix(p='SOAP-ENC', u='http://www.w3.org/2003/05/soap-encoding')    msgId2 = Element('Address', ns=wsans).setText('http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous')    msgId1 = Element('ReplyTo', ns=wsans).insert(msgId2)    msgId1.append(mustAttribute)    msgId3 = Element('To', ns=wsans).setText('http://10.10.10.10:32954')    msgId3.append(mustAttribute)    client.set_options(soapheaders=[msgId, msgId1, msgId3, msgId2])    # Create 'token' object to pass as an argument using the 'factory' namespace    token = client.factory.create('ns4:ReferenceToken')    # Create 'dest' object to pass as an argument and values passed to this object    dest = client.factory.create('ns4:PTZVector')    dest.PanTilt._x=1    dest.PanTilt._y=4.9    dest.Zoom._x=1    # Create 'speed' object to pass as an argument and values passed to this object    speed = client.factory.create('ns4:PTZSpeed')    speed.PanTilt._x=0    speed.PanTilt._y=0    speed.Zoom._x=1    # 'AbsoluteMove' method invoked passing in the new values entered in the above objects    try:        result = client.service.AbsoluteMove(token, dest, speed)        print "absoluteMove result ", result        return result    except suds.WebFault, e:        print "suds.WebFaults caught: "        print eif __name__ == '__main__': result = absoluteMove()

This moves the camera. To change the type of soap-envelope check my next question.

You can add logging into this script whci allow's you to check what xml command you have sent which is handy:

import logginglogging.basicConfig(level=logging.INFO)logging.getLogger('suds.client').setLevel(logging.DEBUG)

The location can be put into the script as an option if the location is not in the wsdl file.
