## Introduction
|
|
|
|
`fastapi-cache` is a tool to cache fastapi response and function result, with backends support `redis` and `memcache`.
|
|
|
|
## Features
|
|
|
|
- Support `redis` and `memcache` .
|
|
- Easily integration with `fastapi`.
|
|
- Support http cache like `ETag` and `Cache-Control`.
|
|
|
|
## Requirements
|
|
|
|
- `asyncio` environment.
|
|
- `redis` if use `RedisBackend`.
|
|
- `memcache` if use `MemcacheBackend`.
|
|
|
|
## Install
|
|
|
|
```shell
|
|
> pip install fastapi-cache2[redis]
|
|
```
|
|
|
|
or
|
|
|
|
```shell
|
|
> pip install fastapi-cache2[memcache]
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Quick Start
|
|
|
|
```python
|
|
import aioredis
|
|
import uvicorn
|
|
from fastapi import FastAPI
|
|
from starlette.requests import Request
|
|
from starlette.responses import Response
|
|
|
|
from fastapi_cache import FastAPICache
|
|
from fastapi_cache.backends.redis import RedisBackend
|
|
from fastapi_cache.decorator import cache_response, cache
|
|
|
|
app = FastAPI()
|
|
|
|
|
|
@cache()
|
|
async def get_cache():
|
|
return 1
|
|
|
|
|
|
@app.get("/")
|
|
@cache_response(expire=60)
|
|
async def index(request: Request, response: Response):
|
|
return dict(hello="world")
|
|
|
|
|
|
@app.on_event("startup")
|
|
async def startup():
|
|
redis = await aioredis.create_redis_pool("redis://localhost", encoding="utf8")
|
|
FastAPICache.init(RedisBackend(redis), prefix="fastapi-cache")
|
|
|
|
```
|
|
|
|
### Use `cache_response`
|
|
|
|
If you want cache `fastapi` response transparently, you can use cache_response as decorator between router decorator and view function and must pass `request` as param of view function.
|
|
|
|
And if you want use `ETag` and `Cache-Control` features, you must pass `response` param also.
|
|
|
|
### Use `cache`
|
|
|
|
You can use `cache` as decorator like other cache tools to cache common function result.
