代码

from fastapi import FastAPI
import aioredis

app = FastAPI()

@app.on_event('startup')
async def startup_event():
    # 线程池
    app.state.redis_client  = aioredis.from_url('redis://xxx.xxx.xxx.xx/0',encoding="utf-8", decode_responses=True)
    

@app.on_event('shutdown')
async def shutdown_event():
    await app.state.redis_client.close()


@app.get('/index')
async def index():
    key = 'liuwei'
    # 设置缓存
    await app.state.redis_client.set(key, '123456')
    
    # 读取
    result = await app.state.redis_client.get(key)
    print(result)
    return {'msg': 'ok'}


if __name__ == '__main__':
    import uvicorn
    uvicorn.run(app='main:app', host='0.0.0.0', port=8001, reload=True)

报错

定位分析

  File "F:\all_django_project\pyscript_demo\fast_api_env\Lib\site-packages\aioredis\exceptions.py", line 14, in <module>
    class TimeoutError(asyncio.TimeoutError, builtins.TimeoutError, RedisError):
TypeError: duplicate base class TimeoutError

启动连接时会报一个TypeError: duplicate base class TimeoutError的错误
问了Copilot，说是兼容性问题，在 Python3.11 中，asyncio.TimeoutError 被移动到了 asyncio.exceptions 模块中，而 aioredis 库没有及时更新以适应这个变化。
所以我们找到aioredis目录下的exceptions.py文件，定位到14行代码
class TimeoutError(asyncio.TimeoutError, builtins.TimeoutError, RedisError):
    pass

所以我们修改为如下代码，即可运行
class TimeoutError(asyncio.exceptions.TimeoutError, RedisError):
    pass
