Hi all,
I'm trying to confirm an Amazon SNS subscription with a web2py controller
action. The Amazon SNS subscription format is described
here<http://docs.amazonwebservices.com/sns/latest/gsg/SendMessageToHttp.html#SendMessageToHttp.confirm>
(through
probably not necessary to understand this problem.)
My controller action (default/amazon_sns_endpoint) basically just emails
request.vars and request.args to myself. It receives a POST request from
the subscription service. However, for some reason, it doesn't seem to be
able to process the POST request, i.e. request.vars and request.args are
always {} and []. (I do, however, get the email.)
Maybe web2py messes up when it handles some of the headers? An example POST
request looks like this:
POST / HTTP/1.1
