We then proceeded to check if the credentials passed in during the course of invoking the class are valid: In the _call_ method, we defined a variable called credentials of type HTTPAuthorizationCredentials, which is created when the JWTBearer class is invoked. In the _init_ method, we enabled automatic error reporting by setting the boolean auto_error to True. So, the JWTBearer class is a subclass of FastAPI's HTTPBearer class that will be used to persist authentication on our routes. credentials else : raise HTTPException ( status_code = 403, detail = "Invalid authorization code." ) def verify_jwt ( self, jwtoken : str ) -> bool : isTokenValid : bool = False try : payload = decodeJWT ( jwtoken ) except : payload = None if payload : isTokenValid = True return isTokenValid credentials ): raise HTTPException ( status_code = 403, detail = "Invalid token or expired token." ) return credentials. scheme = "Bearer" : raise HTTPException ( status_code = 403, detail = "Invalid authentication scheme." ) if not self. _call_ ( request ) if credentials : if not credentials. _init_ ( auto_error = auto_error ) async def _call_ ( self, request : Request ): credentials : HTTPAuthorizationCredentials = await super ( JWTBearer, self ). auth_handler import decodeJWT class JWTBearer ( HTTPBearer ): def _init_ ( self, auto_error : bool = True ): super ( JWTBearer, self ). # app/auth/auth_bearer.py from fastapi import Request, HTTPException from curity import HTTPBearer, HTTPAuthorizationCredentials from.
