JWTVerify Instructions

Input: Request with Authorization header, shared secret. Output: Verified user claims or 401 error. Steps:

  1. Install dependencies if needed (jose, fastapi-security).
  2. Generate middleware code. Example Code: from fastapi import Depends, HTTPException from jose import JWTError, jwt from fastapi.security import HTTPBearer security = HTTPBearer() async def verify_jwt(token: str = Depends(security)): try: payload = jwt.decode(token.credentials, SECRET_KEY, algorithms=["HS256"]) return payload except JWTError: raise HTTPException(401, "Invalid token")
