5. It sends the HTTP request and reads the response.

If there's a problem with the connection, OkHttp will select another route and try again. This allows OkHttp to recover when a subset of a server's addresses are unreachable. It's also useful when a pooled connection is stale or if the attempted TLS version is unsupported.

after a failed authentication, they used the HTTP status code `403 Forbidden`.

Starting with FastAPI version `0.122.0`, they use the more appropriate HTTP status code `401 Unauthorized`, and return a sensible `WWW-Authenticate` header in the response, following the HTTP specifications, <a href="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1" class="external-link" target="_blank">RFC 7235</a>, <a href="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized" class="external-link"...

falha na autenticação, eles usavam o código de status HTTP `403 Forbidden`.

A partir da versão `0.122.0` do FastAPI, eles usam o código de status HTTP `401 Unauthorized`, mais apropriado, e retornam um cabeçalho `WWW-Authenticate` adequado na response, seguindo as especificações HTTP, <a href="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1" class="external-link" target="_blank">RFC 7235</a>, <a href="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized" class="external-link"...

Erstellen Sie eine Variable für das Ablaufdatum des Tokens.

Definieren Sie ein Pydantic-Modell, das im Token-Endpunkt für die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> verwendet wird.

Erstellen Sie eine Hilfsfunktion, um einen neuen Zugriffstoken zu generieren.
