/// tip

Keep in mind that JSON only supports `str` as keys.

But Pydantic has automatic data conversion.

This means that, even though your API clients can only send strings as keys, as long as those strings contain pure integers, Pydantic will convert them and validate them.

And the `dict` you receive as `weights` will actually have `int` keys and `float` values.

/// tip | Совет

Имейте в виду, что JSON поддерживает только ключи типа `str`.

Но Pydantic обеспечивает автоматическое преобразование данных.

Это значит, что даже если пользователи вашего API могут отправлять только строки в качестве ключей, при условии, что эти строки содержат целые числа, Pydantic автоматический преобразует и валидирует эти данные.

# Fehlerbehandlung

Es gibt viele Situationen, in denen Sie einem Client, der Ihre API benutzt, einen Fehler zurückgeben müssen.

Dieser Client könnte ein Browser mit einem Frontend, Code von jemand anderem, ein <abbr title="Internet of Things – Internet der Dinge: Geräte, die über das Internet Informationen austauschen">IoT</abbr>-Gerät, usw., sein.

Sie müssten beispielsweise einem Client sagen:

	"github.com/minio/minio/internal/auth"
	"github.com/minio/minio/internal/bucket/bandwidth"
	"github.com/minio/minio/internal/color"
	"github.com/minio/minio/internal/config"
	"github.com/minio/minio/internal/config/api"
	"github.com/minio/minio/internal/handlers"
	"github.com/minio/minio/internal/hash/sha256"
	xhttp "github.com/minio/minio/internal/http"
	xioutil "github.com/minio/minio/internal/ioutil"
