[web2py] Re: web2py not reading Amazon SNS Subscription Confirmation requests?
Thanks Massimo! It worked. request.body.read() had the JSON.

There is nothing in request.vars because the request contains no HTTP
variables. It is an HTTP post with a json data in the request body. HTTP
does not know anything about json. Web2py has no clue or way to guess the
request body contains json. It may as well be gibberish. Whoever created
the protocol should have used a mime multipart content (which is how forms
are submitted).
Anyway, you can still email yourself:
request.env # the headers
and
request.body.read() # the content of the body
and you will get what you want.

Hi all,
I'm trying to confirm an Amazon SNS subscription with a web2py controller
action. The Amazon SNS subscription format is described
herehttp://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

There is nothing in request.args because I assume the URL is called without
args.
There is nothing in request.vars because the request contains no HTTP
variables. It is an HTTP post with a json data in the request body. HTTP
does not know anything about json. Web2py has no clue or way to guess the
request body contains json. It may as well be gibberish. Whoever created
