Async Cache session expire_after does not set properly

[N4S4]

Good dday,

With below code:

import asyncio
from homeassistant_api import Client
from aiohttp_client_cache import CachedSession, FileBackend
from datetime import timedelta
import logging

logging.basicConfig(filename='log.log', encoding='utf-8', level=logging.DEBUG)

hassurl = 'MY URL'
token = 'MY TOKEN'

client = Client(
    hassurl,
    token,
    async_cache_session=CachedSession(cache=FileBackend(),
                                      expire_after=timedelta(seconds=5)),
    use_async=True
)


async def main():
    async with client:
        while True:
            door = await client.async_get_state(entity_id='sensor.testing')
            if door.state == 'on':

                return True
            else:
                print(door)


asyncio.get_event_loop().run_until_complete(main())

whenever I run this code it works properly except for the update of the cache

looking at the debug log i find this string:

DEBUG:aiohttp_client_cache.cache_control:Determining expiration time based on: -1

whatever I set as expire_after in CachedSession it will always be set to -1

does this event occur to me only?

I can reproduce this.

I've looked around and it looks like the expire_after parameter actually goes to the backend instead.

cache=FileBackend(expire_after=timedelta(seconds=5)),

Here's where I found this, on the docs for asyncio_client_cache

[N4S4]

Yes it works flawlessly, thank you so much!
will this be reflected in docs too?

[GrandMoff100]

Oooh yea good point. I will add it to the docs! Thank you for opening an issue about it.

[N4S4]

thank you for the support!

[GrandMoff100]

Happy to help.

[GrandMoff100]

Done :)
