[Soap-Python] List of objects

[Minh Luu]

Thanks for the reply.

I tried to use the version 0.9.x but it doesn't seem to work
with twisted, so I am now using version 0.8.1. The problem
I have is that the client has already been written by a thirdparty,
and I need to write the server side to match the client request.
The *extact* incoming message is like this:

<?xml version="1.0" encoding="UTF-8"?>
<ns6:Envelope xmlns:ns8="http://abc.com/Types.xsd" xmlns:ns2="http://abc.com/Addressing.xsd" 
xmlns:ns3="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:ns4="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:ns5="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:ns6="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns7="http://abc.com/CarrierDelivery.xsd">
   <ns6:Header>
      ....
   </ns6:Header>
   <ns6:Body>
<n7:DeliveryMsg>
 <n7:Despatch>      
   <n7:contacts>
    <n7:contact>
     <n7:name>Allan</n7:name>
     <n7:title>MR</n7:title>
    </n7:contact>
    <n7:contact>
     <n7:name>Julie<n7:/name>
     <n7:title>MS<n7:/title>
   <n7:/contact>
  <n7:/contacts>
 </n7:Despatch>
</n7:DeliveryMsg>
   </ns6:Body>
</ns6:Envelope>
 

My soap method is:

class SOAPService(SimpleWSGISoapApp):
    
    @soapmethod(Despatch, _return=String)
    def DeliveryMsg(self, Despatch): 
	...
      return "message received"

The problem I have is there are multiple contact entries in contacts.
Using Array(Contact) doesn't work because the incoming message doesn't
have an array tag around the contact.

Can I use the Any class like, Contacts = Any, and handle the xml within
my app. If so, how can I get the xml value of the Contacts?

THANK AGAIN FOR YOUR HELP.

what version of soaplib is it?

the sample xml does not contain a method call, nor namespace
qualifications. soaplib won't accept that *exact* message inside a soap
envelope. you need to define some methods.

here's what i'd do (with 0.9.x, minus imports)

class Contact(ClassSerializer):
        name = String
        title = String

class Contacts(ClassSerializer):
        contact = Array(Contact)

class ServiceDefinition(soaplib.service.DefinitionBase):
    @rpc(_returns=Array(Contact))
    def get_contacts(self)
        c1 = Contact()
        c1.name = 'punk'
        c1.title = 'ceo'

        c2 = Contact()
        c2.name = 'nerd'
        c2.title = 'cto'
        return [c1,c2]


look here for an example about what to do with that service:
