FastAPI 🏗 🔛 🔝 **Pydantic**, & 👤 ✔️ 🌏 👆 ❔ ⚙️ Pydantic 🏷 📣 📨 & 📨.

✋️ FastAPI 🐕‍🦺 ⚙️ <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> 🎏 🌌:

```Python hl_lines="1  7-12  19-20"
{!../../docs_src/dataclasses/tutorial001.py!}
```

- All sites must be using the **same** external IDP(s) if any.
- For [SSE-S3 or SSE-KMS encryption via KMS](https://min.io/docs/minio/linux/operations/server-side-encryption.html "MinIO KMS Guide"), all sites **must**  have access to a central KMS deployment. This can be achieved via a central KES server or multiple KES servers (say one per site) connected via a central KMS (Vault) server.

    }

  private fun enableHttps() {
    enableHttpsAndAlpn(Protocol.HTTP_1_1)
  }

  private fun enableHttp2() {
    platform.assumeHttp2Support()
    enableHttpsAndAlpn(Protocol.HTTP_2, Protocol.HTTP_1_1)

  private fun enableHttpsAndAlpn(vararg protocols: Protocol) {
    client =
      client.newBuilder()
        .sslSocketFactory(

Aber FastAPI unterstützt auf die gleiche Weise auch die Verwendung von <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a>:

```Python hl_lines="1  7-12  19-20"
{!../../docs_src/dataclasses/tutorial001.py!}
```

///

Dem `status_code`-Parameter wird eine Zahl mit dem HTTP-Statuscode übergeben.

/// info

Alternativ kann `status_code` auch ein `IntEnum` erhalten, so wie Pythons <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

Das wird:

* Diesen Statuscode mit der Response zurücksenden.

/// info | "Информация"

В качестве значения параметра `status_code` также может использоваться `IntEnum`, например, из библиотеки <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a> в Python.

///

Это позволит:

* Возвращать указанный код статуса в ответе.

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

	// Maximum size for http headers - See: https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMetadata.html
	maxHeaderSize = 8 * 1024

	// Maximum size for user-defined metadata - See: https://docs.aws.amazon.com/AmazonS3/latest/dev/UsingMetadata.html
	maxUserDataSize = 2 * 1024

	// maxBuckets upto 500000 for any MinIO deployment.
	maxBuckets = 500 * 1000
