python soap client library


There's a service in internet that i want to query with SOAP protocol. When searching for SOAP libraries for Python this post was informative: https://stackoverflow.com/a/206964. But none of libraries that i tried worked for this specific service. I have PHP script that works:

<?php

$client = new SoapClient('https://personyze.com/site/service/service/social_archive/', array('trace' => true));
$result = $client->__soapCall
(   'select', array
    (   array('server_id'=>123456, 'api_key'=>123456), 'user_id', null, null, false, 0, 1
    )
);
echo $client->__getLastRequestHeaders(), $client->__getLastRequest(), "RESULT:\n";
var_dump($result);

I have made the following attempts to do the same in Python:

1.

from suds.client import Client
client = Client("https://personyze.com/site/service/service/social_archive/")

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/suds-0.3.7-py2.7.egg/suds/client.py", line 109, in __init__
    self.wsdl = Definitions(url, options)
  File "/usr/local/lib/python2.7/dist-packages/suds-0.3.7-py2.7.egg/suds/wsdl.py", line 194, in __init__
    self.build_schema()
  File "/usr/local/lib/python2.7/dist-packages/suds-0.3.7-py2.7.egg/suds/wsdl.py", line 255, in build_schema
    self.schema = container.load()
  File "/usr/local/lib/python2.7/dist-packages/suds-0.3.7-py2.7.egg/suds/xsd/schema.py", line 92, in load
    child.dereference()

  File "/usr/local/lib/python2.7/dist-packages/suds-0.3.7-py2.7.egg/suds/xsd/sxbasic.py", line 330, in dependencies
    raise TypeNotFound(self.ref)
suds.TypeNotFound: Type not found: '(Array, http://schemas.xmlsoap.org/soap/encoding/, )'

2.

from pysimplesoap.client import SoapClient
client = SoapClient(wsdl="https://personyze.com/site/service/service/social_archive/", trace=True)
client.select({"server_id":123456, "api_key":123456}, "user_id")

Much better! The best result for today. The only thing this library does wrong is that it calls method selectRequest() instead of select().

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/pysimplesoap/client.py", line 140, in <lambda>

    raise SoapFault(unicode(response.faultcode), unicode(response.faultstring))

import SOAPpy
client = SOAPpy.SOAPProxy("https://personyze.com/site/service/service/social_archive/", "urn:SocialArchiveServiceProviderwsdl")
client.select({"server_id":123456, "api_key":123456}, "user_id", None, None, False, 0, 2)

SOAPpy.Errors.Error: <Error : expected `SOAP-ENV:Envelope', got `wsdl:definitions'>

Please tell me what can i do to make it work.


Solution

  • The server's WSDL schema seems to be broken - it references named objects without importing them.

    See the suds documentation on fixing broken schemas on how to work around that with suds.

    Also see this question for more details.

    This seems to work for me:

    from suds.xsd.doctor import Import
    from suds.xsd.doctor import ImportDoctor
    from suds.client import Client
    
    
    url = 'https://personyze.com/site/service/service/social_archive/'
    tns = 'urn:SocialArchiveServiceProviderwsdl'
    
    imp = Import('http://schemas.xmlsoap.org/soap/encoding/', 'http://schemas.xmlsoap.org/soap/encoding/')
    imp.filter.add(tns)
    client = Client(url,plugins=[ImportDoctor(imp)])
    
    print client.service.select({"server_id":123456, "api_key":123456}, "user_id")
