Hi Jia.
SOAPpy generates default XML SOAP messaging a bit confusing for web
services.
If you set server.config.debug = 1, you can see the messages generated by
default.
Below I send you a code that worked for me.
Here the code:
===========
from SOAPpy import SOAPProxy
def test_tornadows_sum():
"""test for tornadows
"""
#TODO:in this way, invoking tornadows is also failed, what a pity.
url = "http://localhost:8000/SumService";
# noroot = 0 generate <sum SOAP-ENC:root="1">
# noroot = 1 ommit SOAP-ENC:root="1", <sum>
server = SOAPProxy(url,noroot=1)
# With debug = 1 show the communication and messages soap xml.
server.config.debug = 1
# typed = 0 generates the types into the elements
# <a xsi:type="xsd:int">2</a>
# <b xsi:type="xsd:int">1</b>
# with typed = 1 omits the types into the elements
# <a>2</a>
# <a>1</b>
server.config.typed = 0
print
# sending the parameters a=val1, b=val2, make that respect the elements
# defined in the schema of the wsdl.
print "Result is : "+server.sum(a=200,b=10)
test_tornadows_sum()
I hope help you.
Rodrigo.
