Suds error

[Remy de Boer]

Hi,

I'm trying to connect to the SOAP interface of an innovaphone system.
I'm using the following code to connect to the WSDL file:

from suds.client import Client
>  from suds.xsd.doctor import ImportDoctor, Import
>  from suds.transport.http import HttpAuthenticated
>
>  imp = Import('http://schemas.xmlsoap.org/soap/encoding/')
>  imp.filter.add('http://innovaphone.com/pbx')
>  imp.filter.add('http://innovaphone.com/binding')
>
>  d = ImportDoctor(imp)
>  url = 'http://localhost/pbx800.wsdl'
>  t = HttpAuthenticated(username='****', password='****')
>
>  client = Client(url, transport=t, doctor=d)
>
>  print client
>  print client.service.Version()
>  
The WSDL file I'm using is the same as at:
http://www.innovaphone.com/wsdl/pbx800.wsdl

With the 5th to last line (soap:address location) edited to point to our
PBX server.

running the above script results in the following error:

  File "sudstest.py", line 16, in <module>
>      print client.service.Version()
>    File
>  "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line

>    File

>  602, in invoke
>      result = self.send(soapenv)
>    File
>  "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line
>  643, in send
>      result = self.succeeded(binding, reply.message)
>    File
>  "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/client.py", line
>  678, in succeeded
>      reply, result = binding.get_reply(self.method, reply)
>    File
>
> "/usr/lib/python2.6/site-packages/suds-0.4-py2.6.egg/suds/bindings/binding.py",
>  line 149, in get_reply
>      soapenv.promotePrefixes()
>  AttributeError: 'NoneType' object has no attribute 'promotePrefixes'
>  

When I quote out the "print client.service.Version()" line, it displays all
the methods from the WSDL file, but when I leave it uncommented, the "print
client" line doesn't get printed before the error comes up.

Any idea what's causing this error?

I'm using python version 2.6.6 and suds version 0.4

Thanks in advance!

Hi,
it'd help us to understand the issue, if you'd capture the network traffic 
with a tool like Wireshark or tcpdump, and post it to the mailing list with 
any sensitive information (including the base64-encoded credentials in the 
Authorization HTTP header) removed.

Hi again, took a while..

So I captured some stuffs.  Turns out suds is sending the following:

    <?xml
        version="1.0"
        encoding="UTF-8"
        ?>
    <SOAP-ENV:Envelope
        xmlns:ns3="http://www.w3.org/2001/XMLSchema"
        xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
        xmlns:ns0="http://schemas.xmlsoap.org/soap/encoding/"
        xmlns:ns1="http://innovaphone.com/pbx"
        xmlns:ns2="http://schemas.xmlsoap.org/soap/envelope/"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
        SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/&qu...
        <SOAP-ENV:Header/>
        <ns2:Body>
            <ns1:Initialize>
<ns1:Initialize>
<user xsi:type="xsd:string">SOAP</user>
<appl xsi:type="xsd:string">Python SOAP Wrapper</appl>
<v xsi:type="xsd:boolean">true</v>
<v501 xsi:type="xsd:boolean">true</v501>
<v700 xsi:type="xsd:boolean">true</v700>
<v800 xsi:type="xsd:boolean">true</v800>
            </ns1:Initialize>
            </ns2:Body>
        </SOAP-ENV:Envelope>

When I try to use the Initialize method of the WSDL file.

So what should be happening is that it uses SOAP-ENV:Body, but it's using
ns2:Body instead, which is making the server not recognise the commands.
I also don't understand why I have ns0 through ns3, is this something to do
with the importdoctor?

[Veres-Szentkiralyi Andras]

Using ns2 is not a problem in itself, if you send out a _really_ plain 
request, Body always gets nsX (where 0 <= X <= 9), but if you look at the 
xmlns declarations, it's the same URL as in case of SOAP-ENV:

>         
> xmlns:ns2="http://schemas.xmlsoap.org/soap/envelope/"
>          xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
Following the rules of XML, ns2:Body is fine, since prefix is only a "pointer" 
to the XML namespace URL, which qualifies the tag name (or attribute). On the 
other hand, the reason behind this nsX:Body solution is quite an obscure one 
-- I think, it's related to the suds.sax namespace, the one and only XML 
library used by SUDS historically.

I tried using the service using CXF, but it reported the following message:
WSDLToJava Error: Rpc/encoded wsdls are not supported with CXF

If you manage to make it work with any other SOAP solution, that would make 
things easier, as we'd have a working example as an aid for improvement.
