Python jabón usando soaplib (servidor) y espuma (cliente)

Question

Esta pregunta se relaciona con: Python SOAP server/client

En el caso del jabón con Python, hay recomendación de utilizar soaplib (http://wiki.github.com/jkp/soaplib) como servidor de jabón y espuma (https://fedorahosted.org/suds/) como un cliente de jabón. Mi objetivo es crear servicios de soap en python que puedan ser consumidos por varios clientes (java, etc.). Probé el ejemplo HelloWorld de soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). Funciona bien cuando el cliente también está utilizando soaplib.

Luego, traté de usar espuma como cliente consumiendo los servicios HelloWorld y falla. -¿Por qué está pasando esto? ¿El servidor soaplib tiene problemas para ser consumido por diferentes clientes?

Aquí el código del servidor:

from soaplib.wsgi_soap import SimpleWSGISoapApp 
from soaplib.service import soapmethod 
from soaplib.serializers.primitive import String, Integer, Arraycode 
class HelloWorldService(SimpleWSGISoapApp): 
@soapmethod(String,Integer,_returns=Array(String)) 
def say_hello(self,name,times): 
    results = [] 
    for i in range(0,times): 
     results.append('Hello, %s'%name) 
    return results 

if __name__=='__main__': 
from cherrypy.wsgiserver import CherryPyWSGIServer 
#from cherrypy._cpwsgiserver import CherryPyWSGIServer 
# this example uses CherryPy2.2, use cherrypy.wsgiserver.CherryPyWSGIServer for CherryPy 3.0 
server = CherryPyWSGIServer(('localhost',7789),HelloWorldService()) 
server.start() 

Este es el cliente soaplib:

from soaplib.client import make_service_client 
from SoapServerTest_1 import HelloWorldService 
client = make_service_client('http://localhost:7789/',HelloWorldService()) 
print client.say_hello("Dave",5) 

Resultados:

>>> ['Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave', 'Hello, Dave'] 

Este es el cliente espuma:

from suds.client import Client 
url = 'http://localhost:7789/HelloWordService?wsdl' 
client1 = Client(url) 
client1.service.say_hello("Dave",5) 

Resultados:

Answer 1

intenta importar primitivas en su clase:

class HelloWorldService(SimpleWSGISoapApp): 
    from soaplib.serializers.primitive import String, Integer, Arraycode 
    @soapmethod(String,Integer,_returns=Array(String))
