Action Message Format RPC¶
Action Message Format (AMF) is a binary format used for serializing ActionScript objects. It's primarily used for communication between Flash and a server, though it can be used from clients in other languages as well.
AMF support is provided by utilizing the PyAMF package.
pyramid_rpc exposes AMF as a Remoting gateway in a similar manner to
PyAMF's Django gateway support. This allows a remoting gateway to be exposed
as a normal Pyramid view.
Exposing AMF Services¶
Exposing functions for AMF remoting is done by setting up standard AMF functions and defining a gateway view:
# yourproject/amfgateway.py
from pyramid_rpc.amfgateway import PyramidGateway
def echo(request, data):
return data
services = {
'myservice.echo': echo
# could include other functions as well
}
echoGateway = PyramidGateway(services)
Then expose the gateway as if it was a standard Pyramid view:
# yourproject/run.py
from pyramid.config import Configurator
from paste.httpserver import serve
if __name__ == '__main__':
config = Configurator()
config.add_view('amfgateway.echoGateway')
app = config.make_wsgi_app()
serve(app, host='0.0.0.0')
The request passed into the service function is the standard Pyramid request
object. It can be disabled by passing expose_request=False into the
PyramidGateway instantiation.
