Y luego la usamos al crear la app de `FastAPI`.

Entonces podrías desactivar OpenAPI (incluyendo las UI de documentación) configurando la variable de entorno `OPENAPI_URL` a una string vacía, así:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

{* ../../docs_src/json_base64_bytes/tutorial001_py310.py ln[1:9,29:35] hl[9] *}

Если вы откроете `/docs`, вы увидите, что поле `data` ожидает байты, закодированные в base64:

<div class="screenshot">
<img src="/img/tutorial/json-base64-bytes/image01.png">
</div>

Вы можете отправить такой HTTP-запрос:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[11, 19] *}

### Проверьте автоматическую документацию API { #check-the-automatic-api-docs }

Теперь запустите команду `fastapi`:

<div class="termy">

```console
$ fastapi dev

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

然後 Traefik 會把它的請求轉發到在 `http://127.0.0.1:8000` 上運行的 Uvicorn。

現在啟動 Traefik：

<div class="termy">

```console
$ ./traefik --configFile=traefik.toml

INFO[0000] Configuration loaded from file: /home/user/awesomeapi/traefik.toml
```

</div>

然後啟動你的應用，使用 `--root-path` 選項：

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

먼저 [가상 환경](../virtual-environments.md)을 만들고 활성화한 다음, `pydantic-settings` 패키지를 설치하세요:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

또는 다음처럼 `all` extras를 설치하면 함께 포함됩니다:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

### 安裝 `pydantic-settings` { #install-pydantic-settings }

首先，請先建立你的[虛擬環境](../virtual-environments.md)，啟用它，然後安裝 `pydantic-settings` 套件：

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

當你用 `all` extras 安裝時，它也會一併包含在內：

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

### 建立 `Settings` 物件 { #create-the-settings-object }
