ZSI sample and issues with the WSDL

[rieh25]

I'm not sure I know enough to help you, but who knows, maybe this could be of
help. I think that technology is more complicated (or ureliable) than it
should. Possibly the best thing to do is not to depend upon already built
wsdl facilities, but instead work with a basic webservice routine, and work
with it around wsdl.

For instance:

## message_builder_py:

import sys, httplib

def send_message(m):

  #construct and send the header


  if m['type'] == 'HTTP': webservice = httplib.HTTP(m['page'], 80)
  elif m['type'] == 'HTTPS': webservice = httplib.HTTPS(m['page'], 443)
  webservice.putrequest("POST", m['post'])
  webservice.putheader("Host", m['host'])
  webservice.putheader("Content-type", m['content-type'])
  webservice.putheader("Content-length", "%d" % len(m['message']))
  webservice.putheader("SOAPAction", m['SOAPAction'])


  webservice.endheaders()

  webservice.send(m['message'])

  # get the response

  statuscode, statusmessage, header = webservice.getreply()

  r = {}
  r['Response'] = {'statuscode': statuscode, 'statusmessage': statusmessage}
  r['header'] = header
  r['res'] = webservice.getfile().read()
  return r

###call in another place:

xml = """
<solicitud>
  <usuario>gamazari</usuario>
  <clave>laclave</clave>
  <ejercicio>%s</ejercicio>
  <mes>%s</mes>
</solicitud>
"""

mensaje = {}
mensaje['funcion'] = 'SIAFCatalogoFacturas'
mensaje['funcion atribs'] = [['xmlns',
'http://tempuri.org/SIAFProxyWS/Service1']]
params = []
params += [{'parametro': 'xml', 'type': 'string', 'valor': xml % (anio,
mes)}]
mensaje['parametros'] = params

mensaje['pagina'] = 'sicoindes.minfin.gob.gt'
mensaje['tipo'] = 'HTTPS'
mensaje['post'] = '/SIAFProxyWs/SIAFPService.asmx'
mensaje['host'] = 'sicoindes.minfin.gob.gt'
mensaje['SOAPAction'] =
'"http://tempuri.org/SIAFProxyWS/Service1/SIAFCatalogoFacturas"'

res = context.Funcionalidad.Utilidades.SOAP.message_builder_py(mensaje)
