1. 创建项目指令：

python -m venv venv
venv\Scripts\activate

2. Requirements

fastapi==0.111.0
uvicorn==0.30.1

3.创建factory文件：

from contextlib import asynccontextmanager
from typing import AsyncGenerator
from fastapi import FastAPI

def creat_app() -> FastAPI:

    async def app_startup(application: FastAPI) -> None:
        print("app starting up.")

    async def app_shutdown(application: FastAPI) -> None:
        print("app shutting down.")

    @asynccontextmanager
    async def lifespan(application: FastAPI) -> AsyncGenerator:
        await app_startup(application)
        yield
        await app_shutdown(application)

    app: FastAPI = FastAPI(
        title = "",
        description = "",
        version = "0.0.1",
        lifespan = lifespan,
    )

4. 使用uvcorn启动项目

import uvicorn

if __name__ == '__main__':
    uvicorn.run(
        "app.factory:create_app",
        host="0.0.0.0",
        port=8080,
        access_log=False,
        reload=True,
        reload_dirs=["app"],
        factory=True,
    )
