kaya-session-redis
Redis-backed session storage for the Kaya web framework.
Provides RedisSessionStore, a SessionStore implementation (from
kaya-session) that persists session data in Redis, so sessions are shared
across processes and hosts.
Usage
from redis.asyncio import Redis
from kaya.core import KayaApp, HttpContext
from kaya.session import SessionMixin
from kaya.session.redis import RedisSessionStore
client = Redis(host='localhost', port=6379)
session = SessionMixin(RedisSessionStore(client))
app = KayaApp(mixins=[session])
@app.GET('/')
async def home(ctx: HttpContext):
n = ctx.session.get('visits', 0) + 1
ctx.session['visits'] = n
await ctx.send_str(200, f'visits: {n}')
Sessions are stored under keys with the prefix kaya:session: (configurable
via the prefix argument). Server-side expiry uses Redis key TTLs and slides
on each access when the session mixin passes a max_age.
Serialization
Session data is serialized with pickle by default, so arbitrary Python
objects can be stored. A different serializer can be plugged in via the
dumps/loads arguments:
import json
store = RedisSessionStore(
client,
dumps=lambda d: json.dumps(d).encode('utf-8'),
loads=lambda b: json.loads(b.decode('utf-8')),
)
Warning: pickle deserialization of untrusted data is unsafe. Only use the default serializer with a trusted Redis server.
