Tornado and Soap web services in python 3.x

[Abhishek Mishra]

Hello,
I am doing a project which uses soap protocol over HTTP. I used Tornado and Inbuild soap library in Tornado WS. I am facing the following problem. Please help us.

1. Can any one tell that whether tornado along with soap web service is available for Python 3.x.
I have tried many soap libraries but found that they are not working on python 3.x, Though they are working on 2.x

2. Please share the details of soap libraries which is compatible with python 3.x and tornado.

3. Is there any pre build version available for the above.


Thanks
Abhishek Misra

Hi, Abhishek.

I made changes to my API tornado-webservices (https://github.com/rancavil/tornado-webservices) to work with Python 3.3.

tornado-webservices is a SOAP API to work over Tornado.

You can install with:

pip install tornado-webserver

Hi,

Can I use this to:

1. Expose web services (not consume)

2. Use complex data type for both input and output

3. Auto generate WSDL

I'm currently using Ladon but it has some bugs. Also I already have a Tornado setup with Python 3.X, so I'm heavily looking forward if I can use this instead!

Regards,

Hi, If you are talking of tornado-webservices api, Yes...

1 You can expose web service: http://tws33-rigby.rhcloud.com/CertService?wsdl
2. Yes, you can see here https://github.com/rancavil/tornado-webservices/blob/master/demos/RegisterService.py
3. Yes, the WSDL is generated automaticaly from the classes.

Hi I really like your work and I think it is very useful.I have been trying to initialized  the webservice class

where i can pass in the persistent object such the domain_manager .

How can i initialize the soap webservice class and pass a parameter in the constructor  on the server side only?

example here is the code

#cloud service

class CloudService(soaphandler.SoapHandler):

        def initialize(self, domain_manager):

            self.domain = domain_manager

        @webservice(_params=str,_returns=Output)

        def test(self, input):

                output = Output()

                output.success.value  = True

                output.message.value ="Testing soap!  "

                for num in range(10,100000):

                  self.client(num)

                return output

and i want to pass the 

def run(self):

      try:

         #initialize the domain manager

          self.domain_manager = DomainManager(SERVER_CONFIG['cloud_database'])

service = [('Authenticate',Authenticate),('CloudService',CloudService,dict(domain_manager=self.domain_manager))]

app = webservices.WSGIWebService(service,**settings)

      except:

         .......

The problem is on the client  when i  try connecting the CloudService 

this is error i got on the server side

initialize() takes exactly 2 arguments (1 given)

Hi Rodrigo,

Thanks a lot for your helpful package. We've been using it.

Can you tell me how do we make a field of a complex-type element optional? So that if we do not include that field of the complex-type object in request, the server will not throw faultstring?

Thanks a lot.
