Implement RBAC in FastAPI with a JWT role dependency
WHAT IT TESTS: FastAPI dependency composition for JWT role validation. ANSWER OUTLINE: build a dependency that decodes the JWT, checks the role, raises 403 if not admin, and inject via Depends. RED FLAG: parsing headers inside route not using dependencies.
WHAT IT TESTS: designing composable FastAPI dependencies that enforce RBAC by inspecting JWT claims outside business logic. ANSWER OUTLINE: first, create a get_current_user dependency to extract and verify the JWT; second, build a require_role dependency that checks the role claim and raises HTTPException with status 403 if unauthorized; third, apply it with Depends. RED FLAG: decoding JWTs inside the route handler, hardcoding role strings, or returning 401 instead of 403 for insufficient privileges.
