En algunos casos de uso especiales (probablemente no muy comunes), podrías querer **restringir** los parámetros query que deseas recibir.

この`app`はコマンドで`uvicorn`が参照するものと同じです:

<div class="termy">

```console
$ uvicorn main:app --reload

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

</div>

以下のようなアプリを作成したとき:

{* ../../docs_src/first_steps/tutorial002.py hl[3] *}

そして、それを`main.py`ファイルに置き、次のように`uvicorn`を呼び出します:

<div class="termy">

```console

<div style="text-align: right; margin-right: 10%;">Kabir Khan - <strong>Microsoft</strong> <a href="https://github.com/fastapi/fastapi/pull/26" target="_blank"><small>(ref)</small></a></div>

---

"_We adopted the **FastAPI** library to spawn a **REST** server that can be queried to obtain **predictions**. [for Ludwig]_"

        assertFalse(matchesTag(tags[0], "<a></a>"));

        assertTrue(matchesTag(tags[1], "<div id=\"main\"></div>"));
        assertFalse(matchesTag(tags[1], "<div></div>"));

        assertTrue(matchesTag(tags[2], "<p class=\"image\"></p>"));
        assertFalse(matchesTag(tags[2], "<p></p>"));

        assertTrue(matchesTag(tags[3], "<a rel=\"nofollow\"></a>"));

<div style="text-align: right; margin-right: 10%;">Kabir Khan - <strong>Microsoft</strong> <a href="https://github.com/fastapi/fastapi/pull/26" target="_blank"><small>(ref)</small></a></div>

"_We adopted the **FastAPI** library to spawn a **REST** server that can be queried to obtain **predictions**. [for Ludwig]_"

Cette `app` est la même que celle à laquelle fait référence `uvicorn` dans la commande :

<div class="termy">

```console
$ uvicorn main:app --reload

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

</div>

Si vous créez votre app avec :

{* ../../docs_src/first_steps/tutorial002.py hl[3] *}

## Gunicorn und Uvicorn installieren

<div class="termy">

```console
$ pip install "uvicorn[standard]" gunicorn

---> 100%
```

</div>

Dadurch wird sowohl Uvicorn mit zusätzlichen `standard`-Packages (um eine hohe Leistung zu erzielen) als auch Gunicorn installiert.

## Gunicorn mit Uvicorn-Workern ausführen

Dann können Sie Gunicorn ausführen mit:

<div class="termy">

```console

## Check the Docs { #check-the-docs }

You can see the query parameters in the docs UI at `/docs`:
