Minimal example of implementation with encode and decode

[brunolnetto]

I implemented a minimal example for this library on my FastAPI app. However, I do not know how to add the JWT_SECRET to the JWT instance using library objects.

Expected Result

from datetime import timedelta
from os import environ
from typing import Dict
from time import time
from jwt import JWT

JWT_SECRET = str(environ.get('JWT_SECRET'))
JWT_ALGORITHM = str(environ.get('JWT_ALGORITHM')) 

def token_response(token: str):
    return {
        "access_token": token,
        "token_type": "bearer"
    }

def signJWT(user_id: str, expires_delta: timedelta) -> Dict[str, str]:
    payload = {
        "user_id": user_id,
        "expires": time() + 600
    }
    jwt_obj = JWT()

    token = jwt_obj.encode(payload, key=JWT_SECRET, alg=JWT_ALGORITHM)

    return token_response(token)

def decodeJWT(token: str) -> dict:
    try:
        jwt_obj = JWT()

        decoded_token = jwt_obj.decode(token, key=JWT_SECRET, alg=JWT_ALGORITHM)
        
        return decoded_token if decoded_token["expires"] >= time.time() else None
    except:
        return {}

Actual Result

E TypeError: key must be an instance of a class implements jwt.AbstractJWKBase
