How can I create a basic Soap server with spyne in django - django

Question

I want to create a server which uses Django and make and take response as SOAP, so I try to use spyne for this reason but I can't run the given code
class HelloWorldService(ServiceBase):
#rpc(Unicode, Integer, _returns=Iterable(Unicode))
def say_hello(ctx, name, times):
"""Docstrings for service methods appear as documentation in the wsdl.
<b>What fun!</b>
#param name the name to say hello to
#param times the number of times to say hello
#return the completed array
"""
for i in range(times):
yield u'Hello, %s' % name
application = Application([HelloWorldService], 'spyne.examples.hello.soap',
in_protocol=Soap11(validator='lxml'),
out_protocol=Soap11())
wsgi_application = WsgiApplication(application)
if __name__ == '__main__':
import logging
from wsgiref.simple_server import make_server
logging.basicConfig(level=logging.DEBUG)
logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)
logging.info("listening to http://127.0.0.1:8000")
logging.info("wsdl is at: http://localhost:8000/?wsdl")
server = make_server('127.0.0.1', 8000, wsgi_application)
server.serve_forever()

Answer 1

Remove validator='lxml' option in in_protocol
I don't know the reason, the validator took a long time response or did not work.
And add import statements
from spyne import Application, rpc, ServiceBase, Iterable, Integer, Unicode
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication
class HelloWorldService(ServiceBase):
#rpc(Unicode, Integer, _returns=Iterable(Unicode))
def say_hello(ctx, name, times):
"""Docstrings for service methods appear as documentation in the wsdl.
<b>What fun!</b>
#param name the name to say hello to
#param times the number of times to say hello
#return the completed array
"""
for i in range(times):
yield u'Hello, %s' % name
application = Application([HelloWorldService], 'spyne.examples.hello.soap',
in_protocol=Soap11(),
out_protocol=Soap11())
wsgi_application = WsgiApplication(application)
if __name__ == '__main__':
import logging
from wsgiref.simple_server import make_server
logging.basicConfig(level=logging.DEBUG)
logging.getLogger('spyne.protocol.xml').setLevel(logging.DEBUG)
logging.info("listening to http://127.0.0.1:8000")
logging.info("wsdl is at: http://localhost:8000/?wsdl")
server = make_server('127.0.0.1', 8000, wsgi_application)
server.serve_forever()
This is my test result by Postman and curl
Body of POST commend
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<say_hello xmlns="spyne.examples.hello.soap">

curl POST commend with XML lint for terminal pipeline

And my python version and spyne version
$ python --version
Python 3.10.4
$ pip show spyne
Name: spyne
