Se você usar Hypercorn, ele também tem a opção `--root-path`.

/// note | Detalhes Técnicos

A especificação ASGI define um `root_path` para esse caso de uso.

E a opção de linha de comando `--root-path` fornece esse `root_path`.

## Recap { #recap }

Use the *path operation decorator's* parameter `response_model` to define response models and especially to ensure private data is filtered out.

     * automated nullness tests, which would fail.)

Usamos `int | None` para o campo de chave primária para que, no código Python, possamos *criar um objeto sem um `id`* (`id=None`), assumindo que o banco de dados irá *gerá-lo ao salvar*. O SQLModel entende que o banco de dados fornecerá o `id` e *define a coluna como um `INTEGER` não nulo* no esquema do banco de dados.

Create a variable `ALGORITHM` with the algorithm used to sign the JWT token and set it to `"HS256"`.

Create a variable for the expiration of the token.

Define a Pydantic Model that will be used in the token endpoint for the response.

Create a utility function to generate a new access token.

## Clase de response por defecto { #default-response-class }

Al crear una instance de la clase **FastAPI** o un `APIRouter`, puedes especificar qué clase de response usar por defecto.

El parámetro que define esto es `default_response_class`.

En el ejemplo a continuación, **FastAPI** usará `ORJSONResponse` por defecto, en todas las *path operations*, en lugar de `JSONResponse`.
