Usage

-----

A trivial usage example:

.. code:: python

    import time

    import base64

    from cryptography import fernet

    from aiohttp import web

    from aiohttp_session import setup, get_session

    from aiohttp_session_dynamodb import DynamoDBStorage

    import motor.motor_asyncio as aiomotor

    import asyncio

    async def handler(request):

        session = await get_session(request)

        last_visit = session['last_visit'] if 'last_visit' in session else None

        session['last_visit'] = time.time()

        text = 'Last visited: {}'.format(last_visit)

        return web.Response(text=text)

    def init_dynamo(loop):

        async def init_dynamo(loop):

            url = "dynamodb://localhost:27017"

            conn = aiomotor.AsyncIOMotorClient(

                url, maxPoolSize=2, io_loop=loop)

            return conn

        conn = loop.run_until_complete(init_dynamo(loop))

        db = 'my_db'

        return conn[db]

    async def setup_dynamo(app, loop):

        dynamo = init_dynamo(loop)

        async def close_dynamo(app):

            dynamo.client.close()

        app.on_cleanup.append(close_dynamo)

        return dynamo

    def make_app():

        app = web.Application()

        loop = asyncio.get_event_loop()

        dynamo = setup_dynamo(app, loop)

        session_collection = dynamo['sessions']

        setup(app, DynamoDBStorage(session_collection,

                                max_age=max_age,

                                key_factory=lambda: uuid.uuid4().hex)

                                )

        app.router.add_get('/', handler)

        return app

    web.run_app(make_app())
