Mas nesse caso, a mesma aplicação **FastAPI** irá lidar com a API e a autenticação.

Então, vamos rever de um ponto de vista simplificado:

* O usuário digita o `username` e a `senha` no frontend e aperta `Enter`.
* O frontend (rodando no browser do usuário) manda o `username` e a `senha` para uma URL específica na sua API (declarada com `tokenUrl="token"`).

O = MyOrg
OU = MyOU
CN = MyServerName

[v3_req]
subjectAltName = @alt_names

[alt_names]
IP.1 = 127.0.0.1
DNS.1 = localhost
```

Run `openssl` by specifying the configuration file and enter a passphrase if prompted:

```sh
openssl req -new -x509 -nodes -days 730 -keyout private.key -out public.crt -config openssl.conf
```

Vous pouvez étendre le schéma OpenAPI pour une *opération de chemin* en utilisant le paramètre `openapi_extra`.

### Extensions OpenAPI

Cet `openapi_extra` peut être utile, par exemple, pour déclarer [OpenAPI Extensions](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#specificationExtensions) :
