Webservice + WSDL

Optio’s soaplib makes it really straightforward to write SOAP web service views by using a decorator to specify types. Plus it’s the only Python library, as of today, which is able to generate WSDL documents for your web service.

import web
from soaplib.wsgi_soap import SimpleWSGISoapApp
from soaplib.service import soapmethod
from soaplib.serializers import primitive as soap_types

urls = ("/hello", "HelloService",
        "/hello.wsdl", "HelloService",
        )
render = web.template.Template("$def with (var)\n$:var")

class SoapService(SimpleWSGISoapApp):
    """Class for webservice """

    #__tns__ = 'http://test.com'

    @soapmethod(soap_types.String,_returns=soap_types.String)
    def hello(self,message):
        """ Method for webservice"""
        return "Hello world "+message


class HelloService(SoapService):
    """Class for web.py """
    def start_response(self,status, headers):
        web.ctx.status = status
        for header, value in headers:
            web.header(header, value)


    def GET(self):
        response = super(SimpleWSGISoapApp, self).__call__(web.ctx.environ, self.start_response)
        return render("\n".join(response))


    def POST(self):
        response = super(SimpleWSGISoapApp, self).__call__(web.ctx.environ, self.start_response)
        return render("\n".join(response))

app=web.application(urls, globals())

if __name__ == "__main__":
    app.run()

You can test it with a soaplib client:

>>> from soaplib.client import make_service_client
>>> from test import HelloService
>>> client = make_service_client('http://localhost:8080/hello', HelloService())
>>> client.hello('John')
'Hello world John'

And you can view the WSDL in http://localhost:8080/hello.wsdl
