example.py

import falcon
from falcon import testing


class RedirectorComponent(object):
    def process_request(self, req, resp):
        raise falcon.HTTPMovedPermanently('http://example.org/foo')


class HelloResource(object):
    def on_get(self, req, resp):
        resp.body = '{"message": "Hello world!"}'


app = falcon.API(middleware=[RedirectorComponent()])
app.add_route('/', HelloResource())

environ = testing.create_environ('/')
srmock = testing.StartResponseMock()

app(environ, srmock)

print(srmock.status)
print(srmock.headers)
