Question about WSSE
by Frank Millman 12 Feb '10

12 Feb '10

Hi all I am fairly new to Web Services, but I need to get to grips with it for the app I am developing. So far, soaplib-lxml for the server and suds for the client are making it all seem relatively painless - many thanks! I have a question regarding Web Services Security (wsse). >From what I can find out, there are two main sources for this - 1. Web Services Security - Username Token Profile 1.0 - Oasis Standard 200401, March 2004 2. Web Services Security: SOAP Message Security 1.1 (WS-Security 2004) - Oasis Standard incorporating Approved Errata, 01 November 2006 AFAICT, suds.wsse implements the first of these. However, I am not sure that it is implemented correctly. According to the document, there are two mandatory elements - UserName and Password, and two optional elements - Nonce and Created. If Nonce and Created are not used, then Password contains the actual password, sent in the clear. If Nonce and Created are used, then Password must be constructed as follows - Password_Digest = Base64 ( SHA-1 ( nonce + created + password ) ) This gives a small degree of protection over the password. It seems to me that suds allows use of Nonce and Created, but still sends the password in the clear, which rather defeats the object. Does this sound right, or am I missing something? Thanks Frank Millman

Using client without WSDL?
by Craig George 11 Feb '10

11 Feb '10

Anyone know if it is possible to use the suds client without a WSDL? I have come across various services that do not use a WSDL and I would like to use the same library (suds) for all of my SOAP calls. For instance, is it possible to provide a URL and Namespace for the client object to post calls to? Thanks

Best way to override URL for Port?
by Ryan Schneider 10 Feb '10

10 Feb '10

I've got WSDL files for a production service, but also want to support using the same WSDL files for the development server. The port is defined like so: <service name="Foo"> <port binding="tns:FooBinding" name="FooPort"> <soap:address location="https://soap.foo.com/v3.3/soap" /> </port> </service> Basically I want to replace soap.foo.com with soap.dev.foo.com, but am not finding a clear path down to the address. I tried something like: client = Client(wsdl_url) client.sd[0].ports[0][0].location = new_url client.someMethod(...) But it still hit the old URL. Any ideas? Thanks, Ryan

suds.TypeNotFound: Type not found: 'ns0:ArrayOfCondition'
by Benjamin Lau 07 Feb '10

07 Feb '10

Hello, I'm trying to use SUDS to make a connection API for Fedora Commons [http://fedora-commons.org] I've been able to get some basic stuff to work with their simpler methods(no args, or just string args), but when I started to try and use some of the more complex methods (findObjects) I ran into the following error: suds.TypeNotFound: Type not found: 'ns0:ArrayOfCondition' I started trying to dig through things trying to figure out what is going on. I was able to instantiate a bunch of the complex types... but it seems like only the types referenced directly in the WSDL seem to end up in the types list that SUDS knows about... so when the complex types reference other complex types... they aren't listed (maybe this is something normal with how WSDL/SOAP behave... I'm kind of new to the whole thing) Any help would be much appreciated. Here's a link to one of the Fedora Commons WSDL definitions: http://www.fedora-commons.org/definitions/1/api/Fedora-API-A.wsdl And I've attached a piece of python code that demonstrates the error as well... and you can see where I was trying to use the doctor... thinking that might be the issue... maybe I've got the syntax wrong. Thanks in advance, Ben

3.8GA raises "maximum recursion depth ... exception"
by Daniel Rodriguez 07 Feb '10

07 Feb '10

Dear Jeff, Scenario: Suds: 3.8GA Python: 2.6.4 OS: Windows XP SP3 Clone executed (inside a thread or inside the main thread but passed to an object derived from Threading.thread, the result is the same) No further operation is performed on the cloned object. Exiting the program raises the following exception (3 in my case, as I create 3 clones): Exception RuntimeError: 'maximum recursion depth exceeded in __subclasscheck__' in <type 'exceptions.AttributeError'> ignored I have not been able to trace the exception, since even with a "try except" around the main loop of my application, the exception is not caught. Maybe someone has experienced the same behaviour when working with threads and clone.

0.3.9 release candidate
by Jeff Ortel 04 Feb '10

04 Feb '10

All, Revision 655 contains all features defined for 0.3.9. Testing is still in progress. Testing includes a reported issue with authentication when the wsdl is cached. If you're interested in helping test, please install 0.3.9 and run in your environment. This really helps. Release notes: * Updated caching. o Replaced stream-based caching in the transport package with document-based caching. o Caches pickled Document objects instead of XML text. 2x Faster! o No more SAX parsing exceptions on damaged or incomplete cached files. * Cached WSDL objects. Entire Definitions object including contained Schema object cached via pickle. * Copy of soap encoding schema packaged with suds. * Refactor Transports to use ProxyHandler instead of urllib2.Request.set_proxy(). * Added WSSE <Timestamp/> and <Expires/> support. See: Timestamp token. After upgrading to 0.3.9, I'd suggest clearing the suds caching directory. This is not required but will help in the event that we have any caching related issues. https://fedorahosted.org/suds/#Development
