  • basic authentication using a token
import falcon

from falcon_dbapi.middlewares.auth_middleware import AuthMiddleware
from falcon_dbapi.middlewares.json_middleware import RequireJSON, JSONTranslator, JsonError
from falcon_dbapi.resources.index import IndexResource
from falcon_dbapi.resources.sqlalchemy import CollectionResource, SingleResource

from sqlalchemy.ext.automap import automap_base
from sqlalchemy import create_engine

from wsgiref import simple_server

engine = create_engine("sqlite:///mydatabase.db")
Base = automap_base()
Base.prepare(engine, reflect=True)

app = application = falcon.API(
    middleware=[
        AuthMiddleware('/', {'project-id': 'token-value'}),
        RequireJSON(),
        JSONTranslator(),
    ]
)

for name, model in Base.classes.items():
    app.add_route('/' + name, CollectionResource(model, engine)),
    app.add_route('/' + name + '/{id}', SingleResource(model, engine)),

app.add_route('/', IndexResource(['/' + name for name in Base.classes.keys()]))
app.add_error_handler(Exception, JsonError.handle)

simple_server.make_server('localhost', 8888, app).serve_forever()
