Python: ZSI, SOAP and .NET web services - problem

• jaroslaw_zabiello / 200 / Tues, 05 May 2009 17:02:00 GMT / Comments (3)
• I try to connect to web services (written in C#/.NET) with latest ZSI
  2.0rc3 library. It just does not work.
  
  from ZSI.ServiceProxy import ServiceProxy
  wsdl = 'http://192.168.0.103/NewWebServices/TemplateInsert.asmx?wsdl'
  print ServiceProxy(wsdl, tracefile=sys.stdout)
  
  "C:\opt\Python25\lib\site-packages\zsi-2.0_rc3-py2.5.egg\ZSI\wstools\WSDLToo
  ls.py",
  line 1116, in getAddressBinding
  WSDLError: No address binding found in port.
  
  This pythonic library must be stupid, because I have no problem to connect
  with... Ruby:
  
  require 'soap/wsdlDriver'
  require 'rexml/document'
  wsdl = 'http://192.168.0.103/NewWebServices/TemplateInsert.asmx?wsdl'
  soap = SOAP::WSDLDriverFactory.new(wsdl).create_rpc_driver
  #soap.wiredump_file_base = 'soapresult'
  p soap.templateInsert('')
  
  It is a shame why Python still has so poor SOAP implementation. Ruby has
  SOAP in *standard library*, Python - not. Even PHP5 has very good SOAP
  library built in.
  
  I tried to use different library - SOAPpy, but I couldn't. It requires
  fpconst library which cannot be installed because its server does not
  respond at all. What a shit...
  
  Why nobody wants to add SOAP to standard Python library? XML-RPC was added
  and it works without any problems.

     I concur! When I tried to use ZSI the first time, it turned out it has
     no support for attachments. Next time I it turned out that it requires
     PyXML, which has no support and cannot be installed for Window + Python
     2.5. Then I needed to use WSSE login, and then I wanted to authenticate
     with x509. Too many problems. SOAP support for Python is bad indeed.

     Unfortunately, cursing won't help. It would be the best to join the ZSI
     group - it is where we can help. However, it is an interesting question.
     Ruby has smaller community, how could they implement a standard SOAP lib?
     
     My personal opinion is that SOAP is a piece of shit itself. It is
     hampered from the beginning. If you are interested why, read this:

     l]
     
     XML-RPC is a fantastic, often undervalued protocol. You can create a
     new, secure XML-RPC server in Python within 5 minutes. You can write a
     client for it within one minue. It is REALLY simple. I'm using it
     continuously.
     
     In contrast, SOAP is overcomplicated and anything but simple. No one
     should create new web services using SOAP. We have enough problems with
     the existing ones. :-(
     
     Despite SOAP is even not a finished standard, big software companies are
     pushing the technology, can someone explain why? Is it because it only
     works correctly with Java and .NET? I guess the reasons are quite
     financial. :-(

     The problem is I see no errors in my WSDL. Pythonic implementation of SOAP
     is just crapy.

     As Lawrence suggested, did you try soaplib? It is a newer project. Try
     the more recent svn version
     svn co https://svn.optio.webfactional.com/soaplib/trunk soaplib
     
     In my experience, it is more compliant than ZSI, although I mainly
     used it as a server than a client.
