What steps will reproduce the problem?
1. Tried many combinaisions for 2 hours such as :
    dispatcher.register_function('get_device_list_list',
        webserv.get_device_list_list,
        returns={'Result': [{str: str}]},
        args = {})
2. Defining my client : client = SoapClient(wsdl = "http://127.0.0.1:8080/", 
trace = True)

3. I never have the answer, usually it breaks at the client definition.

What is the expected output? What do you see instead?
- Generate a message such as : 
<Result><ItemA>Value1</ItemA><ItemB>Value2</ItemB>....<ItemX>Value26</ItemX></Re
sult>
- And client parse it correctly in a dict such as 
{'ItemA': 'Value1', ... }

What version of the product are you using? On what operating system?
Version 1.02a on UbuntuS erver 10.04.

Please provide any additional information below.

What steps will reproduce the problem?
1.call a soap method that doesnt require arguments

and wsdl file attached.

For the attached WSDL, there is a requirement to provide a username, password, 
and access key via custom SOAP Headers in order to use the Web Service.  Python 
SUDS supports this as per 
https://fedorahosted.org/suds/wiki/Documentation#SOAPHEADERS ; can this be 
added to pysimplesoap?

More detail can be found on page 7 of section 1.6 in the attached PDF.

Thanks in advance!

the server example given in the wiki is not working with the latest version. 
SoapDispatcher is expecting a name argument missing in the example code.

existing code:
dispatcher = SoapDispatcher(
    location = "http://localhost:8008/",
    action = 'http://localhost:8008/', # SOAPAction
    namespace = "http://example.com/sample.wsdl", prefix="ns0",
    trace = True,
    ns = True)

valid code:
dispatcher = SoapDispatcher(
    'my_dispatcher',
    location = "http://localhost:8008/",
    action = 'http://localhost:8008/', # SOAPAction
    namespace = "http://example.com/sample.wsdl", prefix="ns0",
    trace = True,
    ns = True)

I have to place the session id in the header on each client call.  Using this 
same WSDL (https://api.clarizen.com/v1.0/Clarizen.svc) in PHP SoapClient, I 
would do the following:

$header[] = new SoapHeader("http://clarizen.com/api", 'Session', array ("ID" => 
$sessionId));
$client->__setSoapHeaders($header);

This generates:  
<SOAP-ENV:Header><ns1:Session><ns1:ID>some 
guid</ns1:ID></ns1:Session></SOAP-ENV:Header>

ns1="http://clarizen.com/api", btw.

In pysimplesoap, I can successfully login and get the session id. Reading some 
examples, it seems that the header can be added as a normal dict entry. But I'm 
not having luck. 

session = response['LoginResult']['SessionId']

#at this point, I can print session and it's good

client['Session'] = { 'ID' : session }

When I try to execute a remote call, I get this as the request XML...

<?xml version="1.0" encoding="UTF-8"?><soap:Envelope 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Header/>
<soap:Body>

The server obviously responds that the session is missing:

<s:Envelope 
xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode>
s:Client</faultcode><faultstring xml:lang="en-US">Authentication header 
(Session) is missing. Did you forget to 
login?</faultstring></s:Fault></s:Body></s:Envelope>

If a login is needed for Clarizen, they are easy to obtain.  I could create a 
dummy one for my company if needed temporarily.

Thanks.

I'm creating client/service in pysimplesoap for testing interoperability with 
gsoap framework and found small bug in response processing. By default 
pysimplesoap uses default namespace in Request/Response elements like this:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soap:Body>
    <Resolve xmlns="urn:dns:service:1.0"> <!-- default namespace -->
      <Name>osnews.com</Name>
    </Resolve>
  </soap:Body>
</soap:Envelope>

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <soap:Body>
   <ResolveResponse xmlns="urn:dns:service:1.0"> <!-- default namespace -->
     <IP>74.86.31.159</IP>
   </ResolveResponse>
  </soap:Body>
</soap:Envelope>

Everything is ok and IP element has correct namespace. But gsoap generates 
request in a different way creating global namespace prefix and qualifying 
every element with prefix. This changes behavior of pysimplesoap which in 
response also creates namespace prefix but qualifies only top response element:

<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:ds="urn:dns:service:1.0">
  <SOAP-ENV:Body>
    <ds:Resolve>
      <ds:Name>osnews.com</ds:Name>
    </ds:Resolve>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:ds="urn:dns:service:1.0"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SOAP-ENV:Body>
    <ds:ResolveResponse>
      <IP>74.86.31.159</IP>
    </ds:ResolveResponse>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This time IP has default namespace which in this particular message is 
undefined.

The client only supports one namespace to be used. I would like to be able to 
pass multiple namespaces at construction time (maybe in a dictionary form of 
{ns: namespace}).

I created SOAP call from example
http://code.google.com/p/pysimplesoap/wiki/SoapClient#Basic_example_using_WSDL

Headers were defined like in
http://code.google.com/p/pysimplesoap/wiki/SoapClient#WSDL_SOAP_Headers_Example

client['MyTestHeader'] = {'username': 'test', 'password': 'test'}

I expected to see "MyTestHeader" headers on message, but headers were empty 
"<soap:Header/>".

Python version is 2.7.2 and pysimplesoap version is 1.05a.

Currently in dispatch() if there's an error after the invocation of the 
function - during the construction of the return XML - the client will be 
return gibberish rather than a Fault. A simple refactoring allows errors during 
result serialisation (marsalling) to also return a Fault to the client. This is 
attached.

Thank you Mariano for this library. I have made small tests with it and the 
speed is incredible (in comparison with suds)

Let me suggest, as suds does, that it would be a good idea to completely 
separate the "transport" from the generation and parsing of SOAP messages.

Right now (at least in the client) there is urllib, urllib2 and httplib2 code 
mixed with the SOAP parts. And the proxy parameter seems to be too tightly 
coupled to httplib2 where it should be more generic.

Additionally the URL will fail to be fetched if the client has to do that over 
a proxy.

A transport abstraction would allow any HTTP library (httplib2, urllib2 or 
others like my own httxlib) to be plugged in and keep the network code separate 
from the SOAP code.

I am playing a bit around with the sources and will attach an update to this 
"Enhancement Request" for your consideration.

Once again thank you and best regards

I want to return a list of dictionaries, and so I try the folowing function in 
web2py 1.95.1:

@service.soap('MyAdd',returns={'result':[{'a':str, 'b':int, 
'apotelesma':int}]},args={'a':int,'b':int,})
def add(a,b):
    s={'a':str(a),'b':b,'apotelesma':a+b}
    return [s,s]


By calling the function: 
client.MyAdd(a=1,b=2) returns:

{'result': [{'a': u'1'},
            {'apotelesma': 3},
            {'b': 2},
            {'a': u'1'},
            {'apotelesma': 3},
            {'b': 2}]}

What I would expect to see is:
{'result': [{'a': u'1','apotelesma': 3,'b': 2},
            {'a': u'1','apotelesma': 3,'b': 2}]} 

Is this a bug, or I am missing something ?

This works with SUDS

    from suds.client import Client
    url = 'http://wennekers.epcc.ed.ac.uk:8080/axis/services/MetadataCatalogue?WSDL'
    client = Client(url)
    result = client.service.doEnsembleURIQuery("Xpath", "/markovChain", 0, -1)
    print '\nreply(\n%s\n)\n' % str(result)

but not with pysimplesoap

    from pysimplesoap.client import SoapClient                                         
    url = 'http://wennekers.epcc.ed.ac.uk:8080/axis/services/MetadataCatalogue?WSDL'
    client = SoapClient(wsdl=url,trace=False)                                  
    response = client.doEnsembleURIQuery("Xpath", "/markovChain", 0, -1)               
    print response                                                                     

One error is client.py and line
    return lambda self=self, *args, **kwargs: self.wsdl_call(attr,*args,**kwargs)
should be
    return lambda *args, **kwargs: self.wsdl_call(attr,*args,**kwargs)

but also the envelop in the request appears to be is malformed, no data is 
passed to it.

Purpose of code changes on this branch:
- ability to add extra namespaces to server response
- change defined namespace aliases to this provided by client in his request

When reviewing my code changes, please focus on:
- SoapDispatcher.dispatch method which adds extra namespaces to response
- namespaces mapping in SimpleXMLElement

What steps will reproduce the problem?
1. Create a simple client:

c = SoapClient(wsdl=..., trace=True)
c.method()

What is the expected output? What do you see instead?
Fetching the WSDL file fails using urllib2. I do not have httplib2 installed.

What version of the product are you using? On what operating system?
Python 2.6 on Windows.

Please provide any additional information below.
2 bugs:
1. SoapClient creates HTTP wrapper using Http(timeout=TIMEOUT) and the default 
timeout is 60, which urllib2Transport complains with "timeout not supported"

2. SoapClient.fetch(url) calls the HTTP wrapper with self.http.request(url, 
"GET") which complains because urllib2Transport has 5 mandatory args, but is 
called only with 2.

The following patch should fix the bugs:

The universe isn't perfect, nor is the WSDL for a webservice I have to deal 
with.  There should be a way to fixup the incoming WSDL so that pysimplesoap 
will behave correctly. SUDS does this with 'doctors', which seems a reasonable 
idea. Something like:

client = SoapClient(wsdl=wsdlurl, wsdl_fixer=myfunc)

such that myfunc would be called with the retrieved wsdl (perhaps already 
parsed into a SimpleXMLElement tree?) and expected to return the same thing it 
was passed in, but fixed up to the user's liking.

This egg should be on pypi and installabel with easy_install or pip.

Please add a "setuo.py". The easiest way is to use ZopeSkel, Paster to generate 
all needed files.

For my use with the client, I need to modify the XML request before it is sent 
out to the SOAP server.

Just before the XML is sent, the client code does this:
  self.xml_request = request.as_xml()

I currently subclass the client, override __setattr__ to catch the xml_request 
assignment, instantiate a SimpleXMLElement instance with the XML, and 
manipulate it that way.

I think the client should call a method with the XML object just before it 
turns it into a string to allow subclasses to manipulate it. For example:

 self.pre_send_xml_request(request)
 self.xml_request = request.as_xml()

where pre_send_xml_request is a method to be overridden by subclasses who want 
to manipulate the XML before it is sent.

Hi,

When using pysimplesoap with the new wsfev1 afip webservice, I got the 
following error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 9: ordinal 
not in range(128)

(This was for listing bill types, with the 'Nota de Débito' value).  In order 
to fix it, I changed the way that the unicode function was being applied to the 
values.

I'm not sure if it's the best way, but this one at least works.

                         fn = TYPE_UNMARSHAL_FN.get(fn,fn) 
-                        value = fn(unicode(node))
+                        if fn == str:
+                            value = fn(node).decode("utf-8")
+                        else:

                     except (ValueError, TypeError), e:
                         raise ValueError("Tag: %s: %s" % (name, unicode(e)))
                 else:

It would be nice to be able to write something like this:

headers = SimpleXMLElement()
headers.add_child('headername').marshall('attrname', 'attrvalue')
client.call('methodname', headers=headers)

The client code would have this block inside the call method:

    if kwargs.has_key('headers'):
        header_block = xml_body('soapenv:Header')
        for subheader in kwargs['headers'].children():
            header_block.import_node(subheader)

Pysimplesoap.client.SoapClient could not connect a SOAP service, which requires 
the use of client certificates, due to obvious lack of a certificate parameter.

Using httplib2 directly I could retrieve data from the service.

h2 = httplib2.Http()
h2.add_certificate('c.pem','s.pem','someservice.xyz')
url = "https://someservice.xyz/public.asmx?wsdl"
content = h2.request(url,"GET")

Since httplib2 works and is supported by SoapClient, I decided to patch the 
source (patched client.py attached to this report).

SoapClient now takes tree new parameters (clientpem, serverpem and ssldomain) 
and if you're using httplib2 it creates a SSL connection with client 
certificates.

I left all the modifications inside client.py since I only use httplib2, but it 
might be smart to move all parameters into __init__ of various HttpTransports 
and configure each accordingly. 

Sidenote: I started using pysimplesoap only because every other library is even 
more complicated with client certificates. It is a real issue (just check 
stackoverflow on 1001 way of semi solving this problem) and perhaps it might be 
smart if support for client certificates was more developed (ie - directly from 
SoapClient, with all three different libraries).

PS: @reingart, thanks for swift answer.

What steps will reproduce the problem?
1. using https://apitest.authorize.net/soap/v1/Service.asmx?WSDL for my WSDL 
create a client with version 1.02c
2. attempt to call GetCustomerProfile with a profile ID that includes a 
paymentProfile that has a 'creditCard' payment associated with it

What is the expected output? What do you see instead?

I expect the response to be properly parsed and include all information.  
Instead SimpleXML throws an error that 'creditCard' is an invalid type.  Upon 
inspection i see that the 'payment' field of 'CustomerPaymentProfile' has 
expected types of 'None'.  I dug in and figured out that this was because the 
'payment' field has a 'choice' element.

What version of the product are you using? On what operating system?

version 1.02c, in web2py, running from source with the GAE development 
environment.

Please provide any additional information below.

The solution that works for me is the following change (diff based off of 
web2py release Version 1.92.1 (2011-02-16 15:04:40))

1. Invoke SoapClient containing a WSDL which is different from the action URL, 
e.g. client = SoapClient(wsdl="http://example.com/test.wsdl") where the action 
URL is http://example.com/XML/test

2. Running wireshark, you will observe the following output:
GET http://example.com/test.wsdl HTTP/1.0
Host: example.com
User-Agent: Python-urllib/1.17

3. Python stack trace:

What is the expected output? What do you see instead?
I expect that the WSDL would be retrieved.  Unfortunately, instead of 
requesting issuing a GET /test.wsdl, the SoapClient is actually performing GET 
http://example.com/test.wsdl, which will fail with a 404 not found.

What version of the product are you using? On what operating system?
1.02a

What version of the product are you using? On what operating system?
web2py 1.84

Please provide any additional information below.

What steps will reproduce the problem?
1. instantiate a client with a wsdl that has a host : http://localhost
2. as init parameters, set location to something different, say http://foo
3. when calling methods on the wsdl, they will always go to http://localhost 
instead of http://foo

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
linux python 2.4

Please provide any additional information below.
commented out a line, not sure if that has other effects:

client.py:676, commented out the line that looks like
#self.location = port['location']

What steps will reproduce the problem?
1. Create a soap service in web2py (or another framework using 
dispatcher.dispatch)
2. pass in a request that causes a soap fault
3. Get the soap fault's HTTP status code

What is the expected output? What do you see instead?
HTTP response code should be 500, but is (generally) 200 (OK)
Per soap spec here, Soap faults over HTTP should return a 500 response code 
with the fault, due to the underlying HTTP protocol.
http://www.w3.org/TR/2007/REC-soap12-part0-20070427/#L26866
Section 4.1.2 just above Example 11.
pysimplesoap's return from dispatcher.dispatch doesn't return if the HTTP 
response should be 200 or 500, in any way that can be consumed by an external 
service calling it, without parsing the XML, or doing a string search (both bad 
options, for reasons detailed in the web2py bug report)

What version of the product are you using? On what operating system?

If you use a soap client such as SUDS the example method 'adder' in the 
server.py main does not work.

Suds generates slightly different xml for the call to :- 

response = 
client.Adder(p={'a':1,'b':2},dt='2010-07-24',c=[{'d':'1.20'},{'d':'2.01'}])

it generates:- 

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:ns0="http://www.affinitext.com/ACSSoap/" 
                   xmlns:ns1="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:Header/>
    <ns1:Body>
          <ns0:Adder>
               <ns0:p>
                   <ns0:a>1</ns0:a>
                   <ns0:b>2</ns0:b>
               </ns0:p>
               <ns0:dt>2010-07-24</ns0:dt>
               <ns0:c>

               </ns0:c>
          </ns0:Adder>
    </ns1:Body>
</SOAP-ENV:Envelope>

the 2 <ns0:c> elements get collapsed to one.  This is caused inside 
simplexml.py in the unmarshall method.   Basically if a list is encountered it 
is initialized to an empty list for each <ns0:c> rather than appending to the 
existing list.

the fix is simple in that the code 

value = []

just needs to be changed to:-

value = d.setdefault(name, [])

I have attached a diff file to help zero in on the line.

It's better to use python loggers than print statement.
With that change, we are able to see messages only from specified module, or 
only critical messages.

Usage:

import logging
logging.basicConfig(level=logging.DEBUG)
logging.getLogger('pysimplesoap.server').setLevel(logging.DEBUG)
logging.getLogger('pysimplesoap.simplexml').setLevel(logging.DEBUG)

What steps will reproduce the problem?
1. Import a WSDL with a schema element that uses an import.
<types>
  <xsd:schema>
    <xsd:import namespace="XX" schemaLocation="" />
  </xsd:scema>
</types>
2. Execute a call to the operation that requires this type import.

What is the expected output? What do you see instead?
The failure is that the input of the operation may not have a value (None) so 
the ordered dict routine fails because there is no dictionary in the input of 
the operation.

What version of the product are you using? On what operating system?

So far I used soaplib that integrate with django. I'm looking for the solution 
of how to integrate Django with pysimplesoap. Django as server SOAP (WSDL). I 
mean the integration with authentication and django views. Django is currently 
one of the most popular Python frameworks.

Sorry if this is the wrong forum.  First, thank you for your efforts.  This is 
the only Python SOAP client that is close to working for me.

I'm trying to use pysimplesoap to access a client WSDL below:

SoapClient(wsdl="https://api.clarizen.com/v1.0/Clarizen.svc",namespace='http://c
larizen.com/api',trace=True)
response = client.Login(userName="foo",password="bar");

This generates an incorrect namespace on the call:

<soap:Body>
    <Login xmlns="http://clarizen.com/api/Imports">
    <userName>foo</userName><password>bar</password></Login>
</soap:Body>

The correct namespace is: http://clarizen.com/api

It works if I do this:

client.namespace = 'http://clarizen.com/api'
response = client.Login(userName="foo",password="bar");

Is it expected that I need to manually set the namespace like this?

Also, at the very end (using real credentials), I get this:

ValueError: Tag: ServerTime: unconverted data remains: .3473526Z

What steps will reproduce the problem?
1. Use type mapping (ie: wsdl)
2. Call a function that returns a string with non-ascii characters
3.

What is the expected output? What do you see instead?

I'd expect to get a unicode string. Instead the library attempts to convert it 
to a 'str' instance, which throws the following exception;

  ...
  File "/export/home/henry/code/lib/pysimplesoap/pysimplesoap/simplexml.py", line 366, in unmarshall
    raise ValueError("Tag: %s: %s" % (name, unicode(e)))
ValueError: Tag: domesticText: ('ascii', u'Bergs\xe5ker', 5, 6, 'ordinal not in 
range(128)')

Please provide any additional information below.

Because there are two keys mapping to 'string' in TYPE_MAP (in simplexml.py), 
the REVERSE_TYPE_MAP in client.py can map 'string' to either unicode or str. On 
my machine it mapped to str, which caused the failure. Here is the simple fix;

Attached is a path to add SOAP service support for web2py using this library

It extends Service class with soap decorator and soap_serve method.
See Web2Py for detailed information.

Example:
{{{
service = Service(globals())
@service.soap('MyFunction',returns={'result':int,args={'a':int,'b':int,})
def myfunction(a, b):
    return a + b
def call():
    return service()
}}}

The call it with:
{{{
from pysimplesoap.client import SoapClient
client = SoapClient(
        location = "http://localhost:8000/webservices/sample/call/soap",
        action = 'http://example.com/', # SOAPAction
        namespace = "http://example.com/sample.wsdl", 
        soap_ns='soap', # classic soap 1.1 dialect
        trace = True, # print http/xml request and response
        ns = False) # do not add namespace prefix
response = client.MyFunction(a=1,b=2)
print int(response.result)
}}}

I need to connect to a SOAP server which uses cookies to maintain session 
information - but pysimplesoap doesn't support it.

To get round it, I wrote a replacement Http object which is based on the Http 
object defined in the client library, that uses urllib2 for connections:

----
from cookielib import CookieJar
from urllib2 import build_opener, HTTPCookieProcessor, Request

class Http(object):
    def __init__(self):
        from cookielib import CookieJar
        self.opener = build_opener(HTTPCookieProcessor(CookieJar()))

    def request(self, url, method, body, headers):
        f = self.opener.open(Request(url, body, headers))
        return f.info(), f.read()

client.http = Http()
----

I think the client should support this directly by taking a constructor 
argument of "sessions" - which if set to True will enable cookie support.

What steps will reproduce the problem?
1.
from pysimplesoap.client import SoapClient
client = SoapClient(wsdl="http://eklima.met.no/metdata/MetDataService?WSDL", 
trace=True)

What is the expected output? What do you see instead?

Fails with:
   KeyError: u'xmlns:SOAP-ENC'

Disclaimer: I'm not very familiar with WSDL and the more intricate aspects of 
XML, so this might just be a bug in the WSDL (seems to be generated so one 
would hope it's valid though). Sorry if that's the case.

Attached a copy of the WSDL file

The SoapFault exception class takes the faultcode and faultstring, but doesn't 
call the superconstructor with those values.

That means that if the exception is raised, it doesn't print out the faultcode 
or faultstring in the representation of it,
since RuntimeError.__init__ wasn't called.

A better implementation would be:

class SoapFault(RuntimeError):

    def __init__(self, faultcode, faultstring):
        self.faultcode = faultcode
        self.faultstring = faultstring
        RuntimeError.__init__(self, faultcode, faultstring)

    def __str__(self):
        return '%s: %s' % (self.faultcode, self.faultstring)

What steps will reproduce the problem?
1. from pysimplesoap.client import SoapClient
2. SoapClient('http://www.destin8.co.uk/ISLInterface/ISLInterface?WSDL')


What is the expected output? What do you see instead?

The SoapClient instance should be initialised from the WSDL. It instead throws 
the following exception;

Please provide any additional information below.

The problem is the 'xsd' namespace found under schema elements.

This isn't the server I'm using; the WSDL is from a server I found online 
(http://www.google.com/search?q=%22For+a+formal+definition,+please+review+the+Se
rvice+Description%22+%22BEA+WebLogic+Server+8.1%22).
