Calling Web Services from Python
Hello, My Python application calls web services available on the Internet. The web service being called is defined through application user input. The Python built-in library allows access to web services using HTTP protocol, which is not acceptible - generating SOAP messages for arbitrary web services is something i wish to avoid. I need a package/tool that generates web service proxies that will do all the low-level HTTP work. (Someting like the WSDL.EXE tool in .NET Framework) The ZSI and SOAPy packages [1] that i found (should) have those functionalities but either have a bug (SOAPy) or either do not work for arbitrary web services (ZSI). I tried the ZSI wsdl2py script on a wsdl of one of my services, and the script crashes. I suppose the wsdl was "too hard" for the script to parse. Are there any other packages that utilize generation of web service proxies that are compatible with SOAP & WSDL standards? Thank you, ivan zuzak [1] - http://pywebsvcs.sourceforge.net/ -- http://mail.python.org/mailman/listinfo/python-list

You might want to read this, specifically 12.5 and 12.6 for WSDL: http://diveintopython.org/soap_web_services/index.html It uses SOAPpy, which may or may not be different than SOAPy, depending on if you made a typo or not. :) -- http://mail.python.org/mailman/listinfo/python-list

Can you tell us more about SOAPpy bug ? Is it about authentication ? Ivan Zuzak a écrit : >... > I need a package/tool that generates web service proxies that will do > all the low-level HTTP work.

I've successfully used wsdl2py for very complex WSDLs and gotten better results than with .Net's equivalent! Could you post the error you got? I don't know of other Python SOAP modules with WSDL support, sorry. Rob -- http://mail.python.org/mailman/listinfo/python-list

SOAPy : http://soapy.sourceforge.net/ SOAPPy : http://pywebsvcs.sourceforge.net/ The bugged one is SOAPy (parsing errors and something else). I just downloaded and tried SOAPPy and that one crashes too. I get an "Index out of range" error while parsing the wsdl ( in XMLSchema.py ). The traceback is a bit long, so I wont list the whole thing here. Bellow this message is the wsdl of the service for which im trying to get a proxy. If anyone manages to get a proxy out of it - please let me know :).
