Question about the soap envelope namespace
by Chris Frantz 16 Oct '09

16 Oct '09

Hello, It appears that the soap envelope namespace is hardcoded to ' http://schemas.xmlsoap.org/soap/envelope/' in binding.py. I'm trying to talk to a gSOAP based web service that insists the envelope namespace be ' http://www.w3.org/2003/05/soap-envelope'. Unfortunately, I don't have permission to share the WSDL file. Any suggestions? --Chris

Suds memory footprint
by Chris Frantz 01 Oct '09

01 Oct '09

Hello, I would like to use suds to talk to several SOAP services, each using the same WSDL. The wsdl file is rather large (about 500K) and translates to about 50M of memory once parsed. If I do this: c1 = Client('file:myservice.wsdl) c1.set_options(location="https://addr1/soap") c2 = Client('file:myservice.wsdl) c2.set_options(location="https://addr2/soap") (etc) Then each Client instance adds about 50M to my program's memory footprint. Is there any way to parse the WSDL once and create several client objects based on the already-parsed file? A cursory inspection of the Client code suggests I might be able to create the first Client() and then make new instances of client that reference the wsdl, factory and sd members of the original, but contains different Options and possibly it's own ServiceSelector. Suggestions or comments? --Chris

Same WS call - one site OK , another errors..!?
by Chris Brogan 28 Sep '09

28 Sep '09

I am running a Plone site that makes use of suds (0.36) to handle my SOAP requests which generally works well. Allied to this I also have the same set up in a development instance. However, on one particular request, the production site produces errors where the dev site works fine. The following call to a remote service is fine in development but not in production (other calls from the production instance to the same server (ukcolofiniis06) works OK as well): def testPostTime(): url = 'http://ukcolofiniis06/CMSNet/Time/TimeWS/TimeUtilityService.asmx?wsdl' client = Client(url) return client The error returned is as follows: Module suds.client, line 106, in __init__ Module suds.wsdl, line 193, in __init__ Module suds.wsdl, line 255, in build_schema Module suds.xsd.schema, line 90, in load Module suds.xsd.schema, line 277, in open_imports Module suds.xsd.sxbasic, line 874, in open Module suds.xsd.sxbasic, line 892, in download Module suds.sax.parser, line 134, in parse Module xml.sax.expatreader, line 107, in parse Module xml.sax.xmlreader, line 123, in parse Module xml.sax.expatreader, line 211, in feed Module xml.sax.handler, line 38, in fatalError SAXParseException: /tmp/suds/suds-649682136.http:10:2: mismatched tag Any ideas why there could be a difference?

HTTP Error 411: Length Required
by Andreas Maier 25 Sep '09

25 Sep '09

Dear suds developers, I want to convert a perl SOAP client into a python SOAP client. The perl client is initialized like $url = 'https://host:port/cgi-devel/Service.cgi'; $uri = 'https://host/Service'; my $soap = SOAP::Lite -> uri($uri) -> proxy($url); I tried to replicate this in python 2.4.2 with suds 0.3.6 doing from suds.client import Client url="https://host:port/cgi-devel/Service.cgi" client=Client(url) However when running this python script I get the error suds.transport.TransportError: HTTP Error 411: Length Required Is it because of https or what might be the problem? Thank you, Andreas Maier

WSDL Import issue
by Peter Ellis 21 Sep '09

21 Sep '09

I am trying to use suds to call teamtrack webservices (wsdl attached) but am having issues importing the wsdl. If I create the suds client having disabled the use of a proxy[0] I can download the wsdl fine but am unable to import http://schemas.xmlsoap.org/soap/encoding/. If I cancel this creation attempt (Ctrl+c or just let it timeout), leave the wsdl in the cache, then enable the proxy and re-create the client everything works. I have dug through the docs for Doctor and ImportDoctor looking for a way to disable the downloading of this file by setting the location to None but have drawn a blank. Is this even close to being the right way to work round this problem? When this client goes in to production it will not have internet access and will therefore be unable to download the imported schema proxy or no. Here is the client setup code I am currently using: from suds.client import Client from suds.transport.http import HttpTransport server = "some.internal.hostname" t = HttpTransport() proxy = urllib2.ProxyHandler({}) opener = urllib2.build_opener(proxy) urllib2.install_opener(opener) t.urlopener = opener logging.basicConfig(level=logging.DEBUG) logging.getLogger('suds.client').setLevel(logging.DEBUG) self.teamtrack = Client("http://%s/gsoap/ttwebservices.wsdl"%server, transport=t) self.teamtrack.set_options( location="http://%s/gsoap/gsoap_ssl.dll?ttwebservices"%server) Any thoughts or other avenues for investigation are appreciated.

Suds client stopped working on Windows 7
by Rui Neves 17 Sep '09

17 Sep '09

Hi, I have/had a suds client that always worked just fine using some wsdl "generated" using turbogears's tgwebservices. The problem happened when i tried to run this server on windows 7. after some tweaking everything was running fine (i could access the wsdl and use the web services using external clients like soapUI or from a C# GUI i had developed before) except for the suds client who stopped working. The "client = Client(url)" line still works. It creates the service and shows the methods and types available just fine but every method i try to use just returns the following error: URLError: <urlopen error (11004, 'getaddrinfo failed')> (this happens for all client.service."method"() i try to use) I was wondering if anyone experienced similar problems. All my previous problems (already resolved) had to do with the windows 7's IPV6 support. Could it be related? Some additional info: I'm using suds 0.3.4 and python 2.5 As for network connections: I have no proxys enabled and i even disabled the firewall to no avail Thanks in advance, Rui Neves __________ Information from ESET NOD32 Antivirus, version of virus signature database 4434 (20090917) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com

Problems importing wsdl with suds
by Brian Tieman 14 Sep '09

14 Sep '09

Warning: noob here! I have a test service method defined as int addComplexType (TwoNumbers input) Where TwoNumbers is defined in XMDComplexTypes.xsd as <schema targetNamespace="http://gov.anl.aps.tieman/XDMXomplexTypes" elementForDefault="quilified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://gov.anl.aps.tieman/XMDComplexTypes"> ... <complexType name="TestComplexType"> <sequence> <element name="X" type="int"></element> <element name="Y" type="int"></element> </sequence> </complexType> <element name="TwoNumbers" type="tns:TestComplexType"> </element> ... </schema> When I create a client from the WSDL and print it, the method addComplexType is defined as ... ns1 = "http://XMD.tieman.aps.anl.gov/XDMService" ... ns6 = "http://gov.anl.aps.tieman/XMDComplexTypes" ... methods addComplexType (ns1:input input, ) ... types ns6:TestComplexType ... Where does the type ns1:input come from? It's not defined anywhere in the schema. Do I need to use the ImportDoctor to fix this? How? Going on, I can then use the factory to create a variable of the correct type twoNumbers = client.factor.create ('ns6:TestComplexType') and use that as an argument client.service.addComplexType (twoNumbers) but, of course, it bombs. The error I get is "Invalid element in gov.anl.aps.tieman.XMD.stubs.AddComplexTypeRequestInput - X' Any help would be greatly appreciated! Brian

Performance problem
by Nicholas Studt 10 Sep '09

10 Sep '09

The version of suds. - 0.3.6 and 0.3.7 (tried both) A public link or copy of the WSDL. - http://sviis15108.ksde.org/kids_data/kids_webservice.asmx?WSDL A description of the problem including sample code (if possible). Everything works, however the amount of time that it takes for client.service.<function>() to return exceeds the transport time by at least a minute for one function, another ran for an hour before I killed the process. I was able to see that transport time from turning on logging, but I haven't found the right combination of logging to find what is causing the slowdown after the http request is complete. The function that takes a minute has about 403 records with 9 elements each. The one that never returned had 2979 records with 12 elements each. client = Client(options.wsdl) token = client.factory.create('AuthenticationSoapHeader') token.Username = username token.Password = b64encode(hashlib.md5(password).digest()) client.set_options(soapheaders=token) print "Start: %s" % datetime.now() result = client.service.get_Organizations() print "End: %s" % datetime.now() Any help or suggestions would be appreciated. -- Nicholas Studt <nstudt(a)ku.edu>

Attributes on wrapper element
by Tim Smith 07 Sep '09

07 Sep '09

Hello! I'm running into a problem with Exchange Web Services where the wrapper element for a method invocation has a mandatory attribute that I can't figure out how to twiddle with suds. More concretely, I'm trying to make a web services call that looks like: <SOAP-ENV:Body> <ns1:FindItem Traversal="shallow"> ... child elements .... </ns1:FindItem> </SOAP-ENV:Body> and I can't figure out how to make suds generate the xml right. In particular, getCalendarView = client.service.FindItem(_Traversal='shallow', ...) does not work. This looks like an awful lot like ticket 21 (https://fedorahosted.org/suds/ticket/21). I went back into the changelogs and dove into the source a bit since it was suggested that there had been a feature enhancement to cover this since; I didn't see anything promising. suds.bindings.document.Document.param_defs doesn't return any of the wrapper-element attributes, so it doesn't look like there's any opportunity for anything upstream of that to affect them. Is there syntax for this that I'm missing somewhere? This might also be related to the problem Ceser wrote about a few days ago. cheers, tim
