To pytanie dotyczy:Serwer / klient Python SOAP

W przypadku mydła z pytonem zaleca się stosowanie soaplib (http://wiki.github.com/jkp/soaplib) jako serwer mydlany i mydliny (https://fedorahosted.org/suds/) jako klient mydła. Moim celem jest stworzenie usług mydlanych w Pythonie, które mogą być wykorzystywane przez kilku klientów (java itp.). Próbowałem przykładu HelloWorld z soaplib (http://trac.optio.webfactional.com/wiki/HelloWorld). Działa dobrze, gdy klient używa także soaplib.

Następnie próbowałem użyć suds jako klienta korzystającego z usług HelloWorld i zawodzi. -Dlaczego tak się dzieje? Czy serwer soaplib ma problemy z używaniem przez różnych klientów?

Oto kod serwera:

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()

To jest klient 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)

Wyniki:

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

To klient mydlin:

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

Wyniki:
