I'm attempting to run the soaplib Hello World program:

import soaplib
from soaplib.core.service import rpc, DefinitionBase
from soaplib.core.model.primitive import String, Integer
from soaplib.core.server import wsgi
from soaplib.core.model.clazz import Array
from soaplib.core.service import soap


class HelloWorldService(DefinitionBase):
    @soap(String,Integer,_returns=Array(String))
    def say_hello(self,name,times):
        results = []
        for i in range(0,times):
            results.append('Hello, %s'%name)
        import pdb; pdb.set_trace() 
        return results

if __name__=='__main__':
    try:
        from wsgiref.simple_server import make_server
        soap_application = soaplib.core.Application([HelloWorldService], 'tns')
        wsgi_application = wsgi.Application(soap_application)
        server = make_server('localhost', 7789, wsgi_application)
        server.serve_forever()
    except ImportError:
        print "Error: example server code requires Python >= 2.5"

I was having problems connecting to the service, both using a browser and a simple suds client. I used the code from the top answer here to get a list of the methods of my little webservice, as well as they're parameters and types. The result I got wasn't particularly encouraging: 

say_hello(None: say_hello)

So it appears that the reason that I was unable to call the function properly is that it's parameters and types do not appear to register: However, as far as I can tell this should not be the case. I'm particularly dumbfounded as this is the hello world program presented on the soaplib website.

I've searched both here and elsewhere, but I don't seem to find a similar problem anywhere. Any thoughts?

I've tried the soaplib "Hello world" example. It works if you add from soaplib.core.service import soap as you did.

I've installed both soaplib and suds using pip install.

$ pip freeze | grep -e'soaplib\|suds'
soaplib==2.0.0-beta2
suds==0.4

It seems soaplib was refactored to rpclib which was replaced by spyne. It doesn't provide confidence in the project.

  • Indeed, you're right. Do you have any other suggestions for a toolkit for a python-based webservice? – user1401321 Jul 20 '12 at 13:59
  • A general suggestion would be don't use SOAP unless you have specific requirements that justify it. There are tons of [web-frameworks](http://wiki.python.org/moin/WebFrameworks). For a simple service you could start with something like Flask, Pyramid (suitable for RESTful services). `spyne` *might* be the best there is for SOAP-based services (I haven't evaluated SOAP options in a while). – jfs Jul 20 '12 at 14:35
  • Haha, believe me, I'd rather not use SOAP. Sadly, it's one of the requirements of the project I'm working on. :) Thanks for your suggestions! – user1401321 Jul 20 '12 at 14:43
