Search on google for "pyaws" - it's a pretty good wrapper for amazon
ecs. It's not SOAP. You don't really need to use SOAP all the time;
all the Amazon web services have http get (or REST like) calls as
well, and a lot of "toolkits" actually use this method rather than
carry the overhead of SOAP.
To get it to work for GAE, you'll have to add this to the top:
from google.appengine.api import urlfetch
And change the query function to this:
def query(url):
"""Send the query url and return the DOM
Exception is raised if there is errors"""
result = urlfetch.fetch(url)
dom = minidom.parseString(result.content)
errors = dom.getElementsByTagName('Error')
if errors:
e = buildException(errors)
raise e
return dom
This is working in my practice app at http://www.bookdope.com. You'll
end up walking through a dom (document object model) representation of
the response, which is not great, but you can pretty much get the job
done.
But, if you find a TIGHT SOAP toolkit for Python and a nice toolkit
for Amazon ECS (Associates bla bla bla now) built to use it, let me
know :-)
