### Required, can be `None` { #required-can-be-none }

You can declare that a parameter can accept `None`, but that it's still required. This would force clients to send a value, even if the value is `None`.

To do that, you can declare that `None` is a valid type but simply do not declare a default value:

 * Provides common functionality for handling initialization parameters,
 * content length checks, and default method implementations.
 * It defines the basic structure and configuration options for crawler clients.

Bedenken Sie, dass JSON nur `str` als Schlüssel unterstützt.

Aber Pydantic hat automatische Datenkonvertierung.

Das bedeutet, dass Ihre API-Clients nur Strings senden können, aber solange diese Strings nur Zahlen enthalten, wird Pydantic sie konvertieren und validieren.

Und das `dict`, welches Sie als `weights` erhalten, wird `int`-Schlüssel und `float`-Werte haben.

# MinIO STS Quickstart Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

The MinIO Security Token Service (STS) is an endpoint service that enables clients to request temporary credentials for MinIO resources. Temporary credentials work almost identically to default admin credentials, with some differences:

Wenn Sie Daten von einem <abbr title="Client: Eine Software, die sich mit einem Server verbindet.">Client</abbr> (sagen wir, einem Browser) zu Ihrer API senden müssen, senden Sie sie als **Requestbody**.

Ein <abbr title="Anfragekörper">**Request**body</abbr> sind Daten, die vom Client zu Ihrer API gesendet werden. Ein <abbr title="Antwortkörper">**Response**body</abbr> sind Daten, die Ihre API zum Client sendet.
