Python wird sich beschweren, wenn Sie einen Wert mit einem „Default“ vor einem Wert ohne „Default“ setzen.

Aber Sie können die Reihenfolge ändern und den Wert ohne Default (den Query-Parameter `q`) zuerst setzen.

Für **FastAPI** spielt es keine Rolle. Es erkennt die Parameter anhand ihrer Namen, Typen und Default-Deklarationen (`Query`, `Path`, usw.), es kümmert sich nicht um die Reihenfolge.

TLS Configuration History
=========================

OkHttp tracks the dynamic TLS ecosystem to balance connectivity and security. This page is a log of
changes we've made over time to OkHttp's default TLS options.

[OkHttp 3.14][OkHttp314]
------------------------

_2019-03-14_

Remove 2 TLSv1.3 cipher suites that are neither available on OkHttp’s host platforms nor enabled in releases of Chrome and Firefox.
