我想知道是否可以将dependencieskwarg 的结果传递到include_router传递给它的路由器。我想要做的是从x-token请求标头中解码 JWT 并将解码后的有效负载传递给路由books。

我知道我可以编写authenticate_and_decode_JWT为 routers/book.py 中每个路由的依赖项，但这对于大型应用程序来说会非常重复。

主要.py

from typing import Optional
from jose import jwt

from fastapi import FastAPI, Depends, Header, HTTPException, status
from jose.exceptions import JWTError

from routers import books


app = FastAPI()

def authenticate_and_decode_JWT(x_token: str = Header(None)):
    try:
        payload = jwt.decode(x_token.split(' ')[1], 'secret key', algorithms=['HS256'])
        return payload # pass decoded user information from here to books.router routes somehow
    except JWTError:
        raise HTTPException(status_code=status.HTTP_401_UNAUTHORIZED)

app.include_router(
    books.router,
    prefix="/books",
    dependencies=[Depends(authenticate_and_decode_JWT)], 
) …
