Um **die Grundlagen von HTTPS** aus Sicht des Benutzers zu erlernen, schauen Sie sich <a href="https://howhttps.works/" class="external-link" target="_blank">https://howhttps.works/</a> an.

Aus **Sicht des Entwicklers** sollten Sie beim Nachdenken über HTTPS Folgendes beachten:

* Für HTTPS muss **der Server** über von einem **Dritten** generierte **„Zertifikate“** verfügen.

    * Pythonの`datetime.timedelta`です。
    * リクエストとレスポンスでは合計秒数の`float`で表現されます。
    * Pydanticでは「ISO 8601 time diff encoding」として表現することも可能です。<a href="https://docs.pydantic.dev/latest/concepts/serialization/" class="external-link" target="_blank">詳細はドキュメントを参照してください</a>。
* `frozenset`:
    * リクエストとレスポンスでは`set`と同じように扱われます:
        * リクエストでは、リストが読み込まれ、重複を排除して`set`に変換されます。
        * レスポンスでは`set`が`list`に変換されます。

For production you would use `fastapi run` instead. 🚀

Internally, **FastAPI CLI** uses <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, a high-performance, production-ready, ASGI server. 😎

## `fastapi dev`

Running `fastapi dev` initiates development mode.

## Ausführen

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

Das, weil **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

///

Führen Sie das Beispiel aus mit:

///

```Python
{!> ../../docs_src/security/tutorial001.py!}
```

////

## 运行

/// info | "说明"

先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

安装命令： `pip install python-multipart`。

这是因为 **OAuth2** 使用**表单数据**发送 `username` 与 `password`。

///

用下面的命令运行该示例：

<div class="termy">

```console
