### Création d'un `Enum`

Importez `Enum` et créez une sous-classe qui hérite de `str` et `Enum`.

En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.

/**
 * MSRPC implementation for enumerating shares.
 * This class provides functionality to enumerate shared resources
 * on a server using the Server Service RPC interface.
 */
public class MsrpcShareEnum extends srvsvc.ShareEnumAll {

    class MsrpcShareInfo1 extends SmbShareInfo {

        MsrpcShareInfo1(final srvsvc.ShareInfo1 info1) {

import jcifs.smb1.smb1.SmbShareInfo;

/**
 * MS-RPC share enumeration operation.
 *
 * This class implements the Server Service (SRVSVC) ShareEnumAll operation
 * for enumerating network shares on a remote server.
 */
public class MsrpcShareEnum extends srvsvc.ShareEnumAll {

    class MsrpcShareInfo1 extends SmbShareInfo {

        MsrpcShareInfo1(final srvsvc.ShareInfo1 info1) {

import jcifs.CIFSException;
import jcifs.smb.WinError;
import jcifs.util.Hexdump;

/**
 * Exception class for DCE/RPC related errors.
 * This exception is thrown when DCE/RPC protocol errors occur.
 */
public class DcerpcException extends CIFSException implements DcerpcError, WinError {

    /**

Z. B. `pip install python-multipart`.

Das, weil **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

///

Führen Sie das Beispiel aus mit:

<div class="termy">

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

///

	Primeiro, instale <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

	Ex: `pip install python-multipart`.

	Isso ocorre porque o **OAuth2** usa "dados de um formulário" para mandar o **username** e **senha**.

Execute esse exemplo com:

<div class="termy">

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

você o importa e cria uma "instância" da mesma maneira que faria com a classe `FastAPI`:

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

### *Operações de Rota* com `APIRouter`

E então você o utiliza para declarar suas *operações de rota*.

Utilize-o da mesma maneira que utilizaria a classe  `FastAPI`:

```Python hl_lines="6  11  16" title="app/routers/users.py"
