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

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)

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://www.w3.org/2003/05/soap-envelope" xmlns:SOAP
ENC="http://www.w3.org/2003/05/soap-encoding"
<wsa:MessageID SOAP-ENV:mustUnderstand="true">urn:uuid:43268c01-f09c6</wsa:MessageID>
<SOAP-ENV:Header>

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)

addPrefix

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

p
= 'SOAP-ENC'

eg.
wsa

u
= http://address[/code] is the address of the namespace.

A complete script that would run could be:
#!/usr/local/bin/python2.6

import suds
#import logging
from suds.client import Client
from suds.sax.element import Element
from suds.sax.attribute import Attribute
from suds.xsd.sxbasic import Import

def 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 e

if __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 logging
logging.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.
