raised SoapFault in some web service. #94

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
========================================================================
1. execute the following code.
# -*- coding: utf-8 -*-

import logging
import pysimplesoap.client

import pprint

def test_pysimplesoap():
    client = pysimplesoap.client.SoapClient(wsdl='http://www.restfulwebservices.net/wcf/WeatherForecastService.svc?wsdl', trace=True)
    print dir(client)
    print client.namespace
    #pprint.pprint(client.services)

    ret = client.GetCitiesByCountry('korea')
    print ret

    print type(ret[0]), ret[0]

    for r in ret[0]:
        print r

if __name__ == "__main__":
    test_pysimplesoap()
========================================================================

What is the expected output? What do you see instead?
GetCitiesByCountry() is expected to return city names of korea.
But, SoapFault exception is raised.

GoogleCodeExporter commented 9 years ago 
I do more test.
And pysimplesoap.client.SoapClient with WSDL may have a bug to set the 
incorrect namespace.

Below is the generated xml by SoupUI.
========================================================================
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:ns="http://www.restfulwebservices.net/ServiceContracts/2008/01">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:GetCitiesByCountry>
         <!--Optional:-->         
         <ns:Country>korea</ns:Country>
      </ns:GetCitiesByCountry>
   </soapenv:Body>
</soapenv:Envelope>
========================================================================

I compare this xml code with my xml code.
And I found that pysimpleapi set the incorrect namespace.
The namespace may be 
"http://www.restfulwebservices.net/ServiceContracts/2008/01" not 
"http://www.restfulwebservices.net/ServiceContracts/2008/01/Imports".

Following code set the namespace to 
"http://www.restfulwebservices.net/ServiceContracts/2008/01" temporarily.
And works well.

First, self.namespace in SoapClient instance set to correct value at 460 line 
in client.py 
=============================================================
        # Extract useful data:
        self.namespace = wsdl['targetNamespace']
=============================================================

But, self.namespace set to incorrect value at 591 line.
=============================================================
        # check axis2 namespace at schema types attributes
        self.namespace = dict(wsdl.types("schema", ns=xsd_uri)[:]).get('targetNamespace', self.namespace)

sorry, I don't fully understand this, do you have a patch or fix?

I don't have a patch or fix.
I am a beginner for web service(soap,wsdl) and pysimplesoap.
I only test and compare it with other libraries and tools.

The error is fixed in the latest developement version 1.12

Please download and test the latest source code from the repository until the 
release:

https://pysimplesoap.googlecode.com/archive/default.zip

This bug is a pretty much a show stopper for interop between .NET WCF services. 

Even if you utilize the new .NET 4.5 "singleWsdl" feature, you will still 
encounter this issue with xml imports when using complex type paramters, if the 
namespace defined in the attribute [ServiceContract(NameSpace="www.Service")] 
isn't the same as the namespace in [DataContract(Namespace="www.Contract")].

Is this fix being planned be released in a new stable version any time soon?

Thanks for reporting and providing the wsdl, I'm planning to make a new release 
soon (maybe later this month), after fixing some important open issues.

In the meantime, you can download 1.12 from 
https://pysimplesoap.googlecode.com/archive/1.12.zip (or even 1.13) and try it, 
let me know if that solves your problem to see if this bug is a regression.

I have already verified that 1.12 fixes these issues.  Thanks for the quick 
update!  We will be eagerly waiting for the new release :D
