An error in wsdl parsing?

[Pablo Caro Revuelta]

Hello

Is the first time I am trying connect to a soap web service using using 
python. Existing libraries are very poor in my opinion (mainly by the 
interface) but I like suds and would like use it because  is very pleasant.
But I have a problem with the concrete serviece I need to use and I didn't 
find the solution.

The service description is:
https://freeway.demo.lionbridge.com/vojo/FreewayAuth.asmx?WSDL
and I neet call to "Logon" function.
The service runs correctly (I can use it with ZSI)

I tried:

{{{
vojo_auth_uri 
= "https://freeway.demo.lionbridge.com/vojo/FreewayAuth.asmx?wsdl"
logger('suds.serviceproxy').setLevel(logging.DEBUG)
auth_proxy = ServiceProxy(vojo_auth_uri)
logon = auth_proxy.get_instance('Logon')
logon.Username.append("user")
logon.Password.append("password")
print auth_proxy.Logon(logon)

}}}

When I run that code I get this error "You must specify both your username and 
password.at FreewayAuth.Logon(String Username, String Password)"

The problem is that suds does NOT send a correct xml.
The service expects (as documented in 
https://freeway.demo.lionbridge.com/vojo/FreewayAuth.asmx?op=Logon ):

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Logon xmlns="http://tempuri.org/">
      <Username>string</Username>
      <Password>string</Password>
    </Logon>
  </soap:Body>
</soap:Envelope>

But the library send:

<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:tns="http://tempuri.org/" 
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Body>
      <tns:Logon>
         <Username>
            <Username>user</Username>
            <Password>password</Password>
         </Username>
      </tns:Logon>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

The error: Note the extra Username tag.

Am I using the library correctly? Is an library error? 

Thanks in advance

PD: Please excuse my bad english

Hello Pablo,

I tried analyzing the WSDL you gave, and it seems that the "Logon"  
method does not take a "Logon" instance, but two strings; username and  
password.

Here's my code:

import logging
from suds.serviceproxy import ServiceProxy

p = ServiceProxy('freeway.wsdl')
logging.getLogger('suds.serviceproxy').setLevel(logging.DEBUG)

print p.Logon('foo', 'bar')


And here's what suds sends:

<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/ 
" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tns="http://tempuri.org/ 
" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body>
       <tns:Logon>
          <Username>foo</Username>
          <Password>bar</Password>
       </tns:Logon>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>


The service still raises an error:
faultstring = (System.Web.Services.Protocols.SoapException: You must  
specify both your username and password.at FreewayAuth.Logon(String  
Username, String Password))

...but that might be due to the wrong username and password?

HTH,
Jesper

Hello Jesper,

Thank you very much for your response. A response in 15 minutes! I really want 
to use suds :-D

I tested the code you send me with the correct username and password but I 
have the same error. 
I dont know why because It looks like a correct xml.

Maybe you can help me better if I give you more information. 
The ZSI code that works is:
{{{
from FreewayAuth_services import *
fp = open('debug.out', 'a')
proxy =  FreewayAuthLocator().getFreewayAuthSoap(tracefile=fp)
logon = LogonSoapIn()
logon._Username  = user
logon._Password = password
ticket =  proxy.Logon(logon)
print ticket._LogonResult
fp.close()
}}}
where FreewayAuth_services  came from 
wsdl2py  -u https://freeway.demo.lionbridge.com/vojo/FreewayAuth.asmx?WSDL

The xmls in debug.out is:

<SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"

xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:ZSI="http://www.zolera.com/schemas/ZSI/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SO...

xmlns:ns1="http://tempuri.org/"><ns1:Logon><ns1:Use...

The xml output is diferent, maybe ZSI runs because it use namespaces. How can 
I do it with suds?

Cheers

Hi Pablo,

I see the error here, the problem is that the service expects fully  
qualified namespacing on the elements (ns1:Username vs. Username).  
This is specified in your WSDL by elementFormDefault="qualified". This  
is a known issue and Jeff is working on a fix. It should be in trunk  
soon.

Jeff, perhaps you could reply to this message when you've committed a  
fix and Pablo can test it?

Yes, definitely.  I'll post to the list when I have the 
defaultElementForm stuff committed.
