Method addHook

types/instance.d.ts:227–227

* `onRequest` is the first hook to be executed in the request lifecycle. There was no previous hook, the next hook will be `preParsing`. * Notice: in the `onRequest` hook, request.body will always be null, because the body parsing happens before the `preHandler` hook.
