Nós precisamos instalar o `PyJWT` para criar e verificar os tokens JWT em Python.

Certifique-se de criar um [ambiente virtual](../../virtual-environments.md), ativá-lo e então instalar o `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info | Informação

Dann könnten Sie OpenAPI (einschließlich der Dokumentationsoberflächen) deaktivieren, indem Sie die Umgebungsvariable `OPENAPI_URL` auf einen leeren String setzen, wie zum Beispiel:

<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>

Vous pouvez alors désactiver OpenAPI (y compris les interfaces utilisateur des documents) en définissant la variable d'environnement `OPENAPI_URL` sur la chaîne vide, comme ceci :

<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>

Потім ми використовуємо його під час створення застосунку `FastAPI`.

Далі ви можете вимкнути OpenAPI (включно з інтерфейсами документації), встановивши змінну оточення `OPENAPI_URL` у пусту строку, наприклад:

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

### Vérifier la documentation API automatique { #check-the-automatic-api-docs }

Exécutez maintenant la commande `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>

Ardından `FastAPI` app'ini oluştururken bunu kullanıyoruz.

Sonrasında, environment variable `OPENAPI_URL`'i boş string olarak ayarlayarak OpenAPI'yi (UI docs dahil) devre dışı bırakabilirsiniz; örneğin:

<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>

## Несколько воркеров { #multiple-workers }

Можно запустить несколько воркеров с помощью опции командной строки `--workers`:

//// tab | `fastapi`

Если вы используете команду `fastapi`:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

///

## Vários trabalhadores { #multiple-workers }

Você pode iniciar vários trabalhadores com a opção de linha de comando `--workers`:

//// tab | `fastapi`

Se você usar o comando `fastapi`:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

///

## Birden Fazla Worker { #multiple-workers }

Komut satırında `--workers` seçeneğiyle birden fazla worker başlatabilirsiniz:

//// tab | `fastapi`

`fastapi` komutunu kullanıyorsanız:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

## `SQLModel` Kurulumu { #install-sqlmodel }

Önce [virtual environment](../virtual-environments.md) oluşturduğunuzdan emin olun, aktive edin ve ardından `sqlmodel`’i yükleyin:

<div class="termy">

```console
$ pip install sqlmodel
---> 100%
```

</div>
