# Using Dataclasses

FastAPI is built on top of **Pydantic**, and I have been showing you how to use Pydantic models to declare requests and responses.

But FastAPI also supports using <a href="https://docs.python.org/3/library/dataclasses.html" class="external-link" target="_blank">`dataclasses`</a> the same way:

{* ../../docs_src/dataclasses/tutorial001.py hl[1,7:12,19:20] *}

Il est intégré à Let's Encrypt. Ainsi, il peut gérer toutes les parties HTTPS, y compris l'acquisition et le renouvellement des certificats.

# Remove functions from the list of exported variables, they mess up with the `env` command.
for f in $(declare -F -x | cut -d ' ' -f 3);
do
  unset -f "${f}"
done

# Set conditional host mounts
CONDITIONAL_HOST_MOUNTS="${CONDITIONAL_HOST_MOUNTS:-} "
container_kubeconfig=''

E também é usado internamente ao montar sub-aplicações.

## Proxy com um prefixo de caminho removido

Ter um proxy com um prefixo de caminho removido, nesse caso, significa que você poderia declarar um caminho em `/app` no seu código, mas então, você adiciona uma camada no topo (o proxy) que colocaria sua aplicação **FastAPI** sob um caminho como `/api/v1`.

Nesse caso, o caminho original `/app` seria servido em `/api/v1/app`.

* 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"`).
* A API checa aquele `username` e `senha`, e responde com um "token" (nós não implementamos nada disso ainda).
