HTTPS Client Authentication
by David Norton 16 Mar '09

16 Mar '09

Hello all, I am somewhat new to Suds but I wanted to share with you a tip on how to get Suds working with client certificates over HTTPS. This was something we couldn't find in any Python SOAP library, but thanks to Suds' extendable nature we were able to pass in the appropriate connection objects. You can read about it here on our blog: http://www.threepillarsoftware.com/soap_client_auth Please let me know if you have any input or questions -- again, I am new to Suds, but I wanted to start contributing back. Thanks, David Norton Three Pillar Software, Inc.

setting cookies in soap headers
by David Bunch 15 Mar '09

15 Mar '09

Hi, How do you add a cookie to suds soap request headers? I need to set a cookie called ASP.NET_SessionId. I read the section on soap headers, but I'm not sure if that applies to what im trying to do. Thanks, -David

Getting method return type
by Mohamed Lrhazi 14 Mar '09

14 Mar '09

hi there, How do I get a method's return type? Browsing through an instance of suds.client, specifically client.wsdl.messages, I see the data is there, but is there an API way for accessing it? Thanks a lot Mohamed.

How to create arrayTypes in suds?
by David Bunch 13 Mar '09

13 Mar '09

Hi I have a question about ArrayTypes. I have a webservice function that takes an ArrayOfPoints, Which is an ArrayType that holds Point objects. Now, I can create the individual Point objects, but how do I create an ArrayOfPoints and add points to it? I tried this: ArrayOfPoints = myClient.factory.create('ArrayOfPoints') but then, how do I add points to it? List operations don't seem to work. And when I do this: ArrayOfPoints = [Point1, Point2, Point3] myClient.service.calculateCenter(ArrayOfPoints) I get a fault error saying that ArrayOfPoints could not be serialized. Any help/insight on this would be much appreciated. Sincerely, -David

Attachments

Hi All, Okay first I need to say AWESOME job on this package. I mean it! This was so easy to use and get started with I couldn't believe it. It is like some sort of sweet black voodoo magic. I should know I've been forced to do Java SOAP for years and have seen many horrors in my time. I didn't see a way to send an Attachment. Unfortunately this is a requirement for the project I am on. I don't suppose I missed something and there really is Attachment support? Since Suds is so easy and wonderful to work with I am hoping for a miracle and that Suds really does support Attachments and I just missed it. Thank You, Kevin Runde There are 10 kinds of people. Those who understand binary and those who don't.

Suds support for WSSE ( with yahoo specific example ).
by Glenn Franxman 12 Mar '09

12 Mar '09

It looks like the latest build has lost some of it's capabilities for handling namespaces. I'm working with some yahoo apis and am really keen on using python/suds for this. Here’s what Yahoo says I should be sending ( note the use of the wsse namespace ): --------------------------------- <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/07/secext" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://amp.yahooapis.com/V1"> <soapenv:Header> <wsse:Security> <wsse:UsernameToken> <wsse:Username>OBFUSCATED</wsse:Username> <wsse:Password>OBFUSCATED_PASS</wsse:Password> </wsse:UsernameToken> </wsse:Security> <license>OBFUSCATED-LICENSE</license> <accountID>OBFUSCATED-ACCOUNT</accountID> </soapenv:Header> <soapenv:Body> ... </soapenv:Body> </soapenv:Envelope> -------------------- Previous versions output ( note how ns1 should have been a wsse equivalent ): ------------------------------------ $ python sudsDemo.py Suds ( https://fedorahosted.org/suds/ ) version: 0.3.4 (beta) build: R440-20090211 Service ( LocationServiceService ) tns="http://amp.yahooapis.com/V1" Prefixes (2) ns0 = "http://amp.yahooapis.com/V1" ns1 = "http://schemas.xmlsoap.org/ws/2002/07/secext" Ports (1): (LocationService) Methods (1): getAccountLocation() Types (3): ApiFault ns1:Security ns1:UsernameToken ERROR:suds.sudsobject:['value'] must be superset of [], ordering ignored ERROR:suds.sudsobject:['value'] must be superset of [], ordering ignored ERROR:suds.client:<?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns0="http://amp.yahooapis.com/V1" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tns="http://amp.yahooapis.com/V1" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header> <Security xmlns="http://schemas.xmlsoap.org/ws/2002/07/secext"> <UsernameToken> <Username>OBFUSCATED</Username> <Password>OBFUSCATED</Password> </UsernameToken> </Security> <tns:license>OBFUSCATED</tns:license> <tns:accountID>OBFUSCATED</tns:accountID> </SOAP-ENV:Header> <SOAP-ENV:Body> <ns0:getAccountLocation/> </SOAP-ENV:Body> </SOAP-ENV:Envelope> Server raised fault: 'Login failed for OBFUSCATED.'

(u"Server raised fault: 'Login failed for OBFUSCATED.'",) -------------------------------- The ns1 namespace is no longer even applied to the Security clause. Also, it looks like the Security extension from r452 didn't make it. Are there plans? To my eyes, the 0.3.4 version I was using looked like it should have worked even though the wsse namespace was applied in a different manner than Yahoo's example shows. I'm wondering what tools they use.

Are multi dimensional arrays supported?
by Mohamed Lrhazi 11 Mar '09

11 Mar '09

Hi all, We have these WSDLs full of SequenceSequence types, that is an array of array of some complex type... I tried instantiating the type, say, mytype, then passing it to a method that expects such beast as [[mytype]], or [ [mytype,],] I always the excpetion that follows. Is this unsupported currently? /usr/lib/python2.5/site-packages/suds-0.3.5-py2.5.egg/suds/client.py in invoke(self, args, kwargs) 469 binding = self.method.binding.input 470 binding.options = self.options --> 471 msg = binding.get_message(self.method, args, kwargs) 472 timer.stop() 473 metrics.log.debug( /usr/lib/python2.5/site-packages/suds-0.3.5-py2.5.egg/suds/bindings/binding.py in get_message(self, method, args, kwargs) 96 content = self.headercontent(method) 97 header = self.header(content) ---> 98 content = self.bodycontent(method, args, kwargs) 99 body = self.body(content) 100 env = self.envelope(header, body) /usr/lib/python2.5/site-packages/suds-0.3.5-py2.5.egg/suds/bindings/rpc.py in bodycontent(self, method, args, kwargs) 61 p = self.mkparam(method, pd, value) 62 if p is not None: ---> 63 root.append(p) 64 n += 1 65 return root /usr/lib/python2.5/site-packages/suds-0.3.5-py2.5.egg/suds/sax/element.py in append(self, objects) 329 child.parent = self 330 continue --> 331 raise Exception('append %s not-valid' % child.__class__.__name__) 332 return self 333 <type 'exceptions.Exception'>: append list not-valid Thanks, Mohamed.

Hello, Was wondering what it would take to make suds clients serializable with (c)Pickle... or does that not make sense? Thanks, Mohamed.

regression in suds 0.3.4
by David Robinson 06 Mar '09

06 Mar '09

Hi all, I've hit what appears to be a bug in suds version 0.3.4. My app was working fine with version 0.3.3 but after upgrading to 0.3.4 it suddenly stopped working. I've attached a sample app that reproduces the problem (it has comments which hopefully explain what's happening). Below is a diff of the request that's created by suds version 0.3.3 and 0.3.4. The actual problem is that <ns0:request xsi:type="GetEventsReq"> is incorrect, it should include the namespace as did version 0.3.3. --- suds-0.3.3 2009-03-06 06:11:41.000000000 +0000 +++ suds-0.3.4 2009-03-06 06:11:30.000000000 +0000 @@ -1,19 +1,18 @@ <SOAP-ENV:Envelope xmlns:ns0="http://www.betfair.com/publicapi/v3/BFGlobalService/" -xmlns:ns1="http://www.betfair.com/publicapi/types/global/v3/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header/> <SOAP-ENV:Body> <ns0:getEvents> - <ns0:request xsi:type="ns1:GetEventsReq"> - <header xmlns="http://www.betfair.com/publicapi/types/global/v3/"> + <ns0:request xsi:type="GetEventsReq"> + <header> <clientStamp>0</clientStamp> <sessionToken>blah</sessionToken> </header> - <eventParentId xmlns="http://www.betfair.com/publicapi/types/global/v3/">7</eventParentId> - <locale xmlns="http://www.betfair.com/publicapi/types/global/v3/" xsi:nil="true"/> + <eventParentId>7</eventParentId> + <locale xsi:nil="true"/> </ns0:request> </ns0:getEvents> </SOAP-ENV:Body> --Dave

Re: Suds and Sharepoint
by Kevin 05 Mar '09

05 Mar '09

Thanks for replying. There seems to be a fair amount of interest out there in automating SharePoint tasks via Python - except that most people can't seem to get it to work. There's a list of public SharePoint examples at https://usmc-sharepoint.securespsites.com/Lists/Public%20SharePoint%20Examp… , including http://www.wssdemo.com/ . The WSDL files can be accessed as described in the developer.com article in my earlier message, e.g. http://www.wssdemo.com/_vti_bin/Lists.asmx?WSDL . -K --- On Thu, 3/5/09, Jeff Ortel <jortel(a)redhat.com> wrote: > From: Jeff Ortel <jortel(a)redhat.com> > Subject: Re: [Fedora-suds-list] Re: Suds and Sharepoint > To: "Kevin" <kehander(a)yahoo.com> > Cc: fedora-suds-list(a)redhat.com > Received: Thursday, March 5, 2009, 6:54 AM > Hey Kevin, > > Thanks for you interest in suds. > > I've been pretty slammed this week but should be able to > look in to this today.
