[web2py] Building a non-trivial SOAP service using web2py

[David Mitchell]

Hello all,

I'm looking at using web2py to build a SOAP service to work as a test
harness for an infrastructure upgrade we're planning.  Unfortunately, all
the web2py SOAP info I've found has been trivial services such as adding 2
numbers together - in my case, I need my SOAP server to be able to do
something more complicated.

The sort of complexity I need to build is something like
http://www.webservicex.com/stockquote.asmx?WSDL
When I query this service from suds, the code looks something like:
>>> import suds
>>> url = 'http://www.webservicex.com/stockquote.asmx?WSDL'
>>> client = suds.client.Client(url)
>>> print client

Suds ( https://fedorahosted.org/suds/ )  version: 0.4 GA  build:
R699-20100913

Service ( StockQuote ) tns="http://www.webserviceX.NET/";
   Prefixes (0)
   Ports (2):
      (StockQuoteSoap)
         Methods (1):
            GetQuote(xs:string symbol, )
         Types (0):
      (StockQuoteSoap12)
         Methods (1):
            GetQuote(xs:string symbol, )
         Types (0):


>>> client.service.GetQuote('IBM')
<StockQuotes><Stock><Symbol>IBM</Symbol><Last>166.98</Last><Date>9/2/2011</Date><Time>4:00pm</Time><Change>0.00</Change><Open>N/A</Open><High>N/A</High><Low>N/A</Low><Volume>200</Volume><MktCap>199.4B</MktCap><PreviousClose>166.98</PreviousClose><PercentageChange>0.00%</PercentageChange><AnnRange>125.39
- 185.63</AnnRange><Earns>12.315</Earns><P-E>13.56</P-E><Name>International
Bus</Name></Stock></StockQuotes>
>>>


I figure my web2py controller code to do this would look something like:

from gluon.tools import Service
service = Service(globals())

@service.soap('GetQuote', returns={SOMETHING_HERE}, args={'symbol':str})
def stock_quote(stock):
    "Return stock quote info - everything is hardcoded..."
    symbol = "IBM"
    last = 166.98
    date = '9/2/2011'
    quote_time = '4:00pm'
    change = 0.00
    #...
    return SOMETHING_HERE

def call():
    return service()


I'm trying to work out what the 2 SOMETHING_HERE pieces should look like in
the above code.

Could someone please point me in the right direction?

Thanks in advance

Dave M.
