SOAP problems

[Rune Hansen]

Ah, well - yes. I'm absolutely no expert on SOAP and I'm inclined to 
agree with Johan Fredrik Øhman...
Anyways: The simplest of clients can be constructed like this:
(be shure to install ZSI 1.2-7)

---
from ZSI.client import Bindings
import sys

c = Binding(url='/',
             ns='',
             host='localhost',
             port=8080,tracefile=sys.stdout)

res = c.echo(1,2,3,4)
print res[0]

 >>[1,2,3,4]
 >>Output from trace
<SOAP-ENV:Envelope
   xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
   xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:xsd="http://www.w3.org/2001/XMLSchema"
   xmlns:ZSI="http://www.zolera.com/schemas/ZSI/"
   SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" >
<SOAP-ENV:Body>
<echo>
<E810dc08 xsi:type="xsd:integer">1</E810dc08>
<E810dbf0 xsi:type="xsd:integer">2</E810dbf0>
<E810dbb4 xsi:type="xsd:integer">3</E810dbb4>
<E810dba8 xsi:type="xsd:integer">4</E810dba8>
</echo>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
.

This may be sufficient to communicate with the soapserver, "echo" beeing 
the SOAP service.

To send named parameters use:
---
from ZSI import *
from ZSI.client import NamedParamBinding
import sys

class Generic:
     def __init__(self,name):
         self.name = name

class tcMyParams(TC.Struct):
     def __init__(self, pname=None,**kw):
         print kw
	TC.Struct.__init__(self, Generic, [
	    TC.Iint('id',unique=1),
	    TC.String('username),
	    TC.String('password'),
             ], pname, inorder=0, **kw);

class myParams:
     typecode = tcMyParams('echo', typed=0)
     def __init__(self,id,username,password):
         self.id=id
         self.username=username
         self.password=password

def SOAPClient(id,username,password):
	soap_client = NamedParamBinding(url='',
         	                        			        ns='',
                 	                        			host='localhost',
                         	                			port=8080,
                                 	        			tracefile=sys.stdout)

         res = 
soap_client.RPC('/','echo',myParams(id,username,password),TC.Any(aslist=1))
	return res[0]

res = SOAPClient(100,'john','doe')

This works for me..and since it works I haven't given it much thought. 
I've adapted the "named parameters" code from a Google/SOAP piece I 
found - it may or may not be the correct way to do it :-)

You'll find how to set up a simple SOAP server in one of the links i 
mentioned in my previous post.

Hope this will get you somewhere.
