Following this tutorial I converted the Unicode to String which has worked fine when following the wsgi tutorial.
For some background I am hosting this in a docker container and exposing the port from the container to the host computer. That is why I'm using 0.0.0.0 as the HOST variable.
python version: 3.8.0
spyne version 2.13.11a0
zeep version 3.4.0
import logging
from twisted.internet import reactor
from twisted.web.server import Site
from spyne import Application, rpc, Service, Iterable, String, UnsignedInteger
from spyne.protocol.soap import Soap11
from spyne.server.twisted import TwistedWebResource
HOST = '0.0.0.0'
PORT = 5050
class HelloWorldService(Service):
@rpc(String, UnsignedInteger, _returns=Iterable(String))
def say_hello(ctx, name, times):
for i in range(times):
yield f'Hello {name}'
application = Application(
[HelloWorldService], 'spyne.examples.twisted.resource_push',
in_protocol=Soap11(validator='lxml'), out_protocol=Soap11(),
)
def main():
resource = TwistedWebResource(application)
site = Site(resource)
logging.basicConfig(level=logging.DEBUG)
logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)
logging.info(f'listening on {HOST}:{PORT}')
logging.info(f'wsdl is at: http://{HOST}:{PORT}/?wsdl')
reactor.listenTCP(PORT, site, interface=HOST)
reactor.run()
if __name__ == '__main__':
main()
Using zeep to test
import zeep
wsdl = 'http://localhost:5050/?wsdl'
client = zeep.Client(wsdl=wsdl)
client.service.say_hello('Daniel', 5)
this is the error

The b'localhost' seems off. Looking at the wsdl generated it is definitely there
