Pero `open()` no usa `async` y `await`.

Por eso, declaramos la función manejadora del evento con `def` estándar en vez de `async def`.

### `startup` y `shutdown` juntos

Hay una gran posibilidad de que la lógica para tu *startup* y *shutdown* esté conectada, podrías querer iniciar algo y luego finalizarlo, adquirir un recurso y luego liberarlo, etc.

`OAuth2PasswordRequestForm` é uma dependência de classe que declara um corpo de formulário com:

* O `username`.
* A `password`.
* Um campo `scope` opcional como uma string grande, composta de strings separadas por espaços.
* Um `grant_type` (tipo de concessão) opcional.

Ce qu'il faut retenir c'est qu'en utilisant les types standard de Python, à un seul endroit (plutôt que d'ajouter plus de classes, de décorateurs, etc.), **FastAPI** fera une grande partie du travail pour vous.

Isso é especialmente útil para uma **base de código grande** onde **as mesmas dependências** são utilizadas repetidamente em **muitas *operações de rota***.

## `Async` ou não, eis a questão

    private SmbTransportInternal exclusiveTransport;
    private boolean nonPooled;

    private final AtomicLong usageCount = new AtomicLong();

    private static final Random RAND = new Random();

    protected SmbTreeConnection(final CIFSContext ctx) {
        this.ctx = ctx;
        this.delegate = null;
    }

    protected SmbTreeConnection(final SmbTreeConnection treeConnection) {

Import the modules installed.

Create a random secret key that will be used to sign the JWT tokens.

To generate a secure random secret key use the command:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

And copy the output to the variable `SECRET_KEY` (don't use the one in the example).

Создайте случайный секретный ключ, который будет использоваться для подписи JWT-токенов.

Для генерации безопасного случайного секретного ключа используйте команду:

<div class="termy">

```console
$ openssl rand -hex 32

09d25e094faa6ca2556c818166b7a9563b93f7099f6f0f4caa6cf63b88e8d3e7
```

</div>

И скопируйте полученный результат в переменную `SECRET_KEY` (не используйте тот, что в примере).
