Agora, execute o comando `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>

E abra a documentação em [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

然後你可以將環境變數 `OPENAPI_URL` 設為空字串，以停用 OpenAPI（包含文件 UI），如下：

<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>

之後若你造訪 `/openapi.json`、`/docs` 或 `/redoc`，會看到如下的 `404 Not Found` 錯誤：

```JSON
{
    "detail": "Not Found"
}

Now, run the `fastapi` command:

<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>

And open the docs at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

You will see the automatic API docs for the main app, including only its own _path operations_:

     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Uvicorn running on <font color="#729FCF"><u style="text-decoration-style:solid">http://0.0.0.0:8000</u></font> <b>(</b>Press CTRL+C to
             quit<b>)</b>
     <span style="background-color:#007166"><font color="#D3D7CF"> INFO </font></span>  Started parent process <b>[</b><font color="#34E2E2"><b>27365</b></font><b>]</b>

接着，你可以通过把环境变量 `OPENAPI_URL` 设为空字符串来禁用 OpenAPI（包括文档 UI），例如：

<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>

然后如果你访问 `/openapi.json`、`/docs` 或 `/redoc`，就会得到一个 `404 Not Found` 错误，例如：

```JSON
{
    "detail": "Not Found"
}

Vous pouvez personnaliser plusieurs configurations de métadonnées dans votre application **FastAPI**.

## Métadonnées pour l'API { #metadata-for-api }

Vous pouvez définir les champs suivants qui sont utilisés dans la spécification OpenAPI et les interfaces utilisateur de documentation automatique de l’API :

| Paramètre | Type | Description |
|------------|------|-------------|
| `title` | `str` | Le titre de l’API. |

이제 `fastapi` 명령어를 실행하세요:

<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>

그리고 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)에서 문서를 여세요.

메인 앱의 자동 API 문서를 보게 될 것이며, 메인 앱 자체의 _경로 처리_만 포함됩니다:

  echo "Error: Generated wheel is too big! Limit is $TFCI_WHL_SIZE_LIMIT"
  echo '(search for TFCI_WHL_SIZE_LIMIT to change it)'
  ls -sh *.whl

# Quick install checks
venv_dir=$(mktemp -d)

else

// traverseAndHeal - traverses on-disk data and performs healing
// according to settings. At each "safe" point it also checks if an
// external quit signal has been received and quits if so. Since the
// healing traversal may be mutating on-disk data when an external
// quit signal is received, this routine cannot quit immediately and
// has to wait until a safe point is reached, such as between scanning
// two objects.

Les modèles, bien qu'ils soient généralement livrés avec une configuration spécifique, sont conçus pour être flexibles et personnalisables. Cela vous permet de les modifier et de les adapter aux exigences de votre projet, ce qui en fait un excellent point de départ. 🏁

Vous pouvez utiliser ce modèle pour démarrer, car il inclut une grande partie de la configuration initiale, la sécurité, la base de données et quelques endpoints d'API déjà prêts pour vous.
