AND main.py file,

@app.get("/")
@cache(expire=60)
async def index(request: Request, response: Response):
    return dict(hello="world")

@app.on_event("startup")
async def startup():
    redis =  aioredis.from_url("redis://127.0.0.1", encoding="utf8", decode_responses=True)
    FastAPICache.init(RedisBackend(redis), prefix="fastapi-cache")

Any assistance is much appreciated! 谢谢大佬
