Defined in:
lib/vayacondios/server/rack/params.rb

Overview

Parses parameters in the request.

Will parse parameters from the query string as well as from the request body.

Rack gets unhappy when the parameters are anything other than a Hash but we want clients to be able to send non-Hash-like request bodies. To support this case, the request's params are stored into the _document key of the params, to be fetched later by Vayacondios::HttpServer#document.
