Usage
-----

A trivial usage example:

.. code:: python

import time
from aiohttp import web
from aiohttp_session import setup, get_session
from aiohttp_session_mongo import MongoStorage
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)


async def init_mongo(loop):
url = "mongodb://localhost:27017"
conn = aiomotor.AsyncIOMotorClient(
url, maxPoolSize=2, io_loop=loop)
db = 'my_db'
return conn[db]


async def setup_mongo(app, loop):
db = await init_mongo(loop)

async def close_mongo(app):
db.client.close()

app.on_cleanup.append(close_mongo)
return db


async def make_app():
app = web.Application()
loop = asyncio.get_event_loop()

db = await setup_mongo(app, loop)
session_collection = db['sessions']

max_age = 3600 * 24 * 365 # 1 year
setup(app, MongoStorage(session_collection, max_age=max_age))

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


web.run_app(make_app())
