### Eine `HTTPException` in Ihrem Code auslösen

`HTTPException` ist eine normale Python-<abbr title="Exception – Ausnahme, Fehler: Python-Objekt, das einen Fehler nebst Metadaten repräsentiert">Exception</abbr> mit einigen zusätzlichen Daten, die für APIs relevant sind.

Weil es eine Python-Exception ist, geben Sie sie nicht zurück, (`return`), sondern Sie lösen sie aus (`raise`).

        return QueryBuilders.wildcardQuery(urlField, queryString).boost(boost);

Vamos começar com um aplicativo **FastAPI** simples:

 *  Fix: Degrade HTTP/2 connections after a timeout. When an HTTP/2 stream times out it may impact
    the stream only or the entire connection. With this fix OkHttp will now send HTTP/2 pings after
    a stream timeout to determine whether the connection should remain eligible for pooling.

Sie können das überschreiben, indem Sie direkt eine `Response` zurückgeben, wie in [Eine Response direkt zurückgeben](response-directly.md){.internal-link target=_blank} gezeigt.
