Backport #25701 by @CaiCandong we refactored `userIDFromToken` for the token parsing part into a new function `parseToken`. `parseToken` returns the string `token` from request, and a boolean `ok` representing whether the token exists or not. So we can distinguish between token non-existence and token inconsistency in the `verfity` function, thus solving the problem of no proper error message when the token is inconsistent. close #24439 related #22119 Co-authored-by: caicandong <50507092+CaiCandong@users.noreply.github.com> Co-authored-by: Jason Song <i@wolfogre.com>
