### `HTMLResponse`

Usa algum texto ou sequência de bytes e retorna uma resposta HTML. Como você leu acima.

### `PlainTextResponse`

Usa algum texto ou sequência de bytes para retornar uma resposta de texto não formatado.

Вы можете объявить некоторые файлы как `bytes`, а некоторые - как `UploadFile`.

/// warning | Внимание

O `secrets.compare_digest()` necessita receber `bytes` ou `str` que possuem apenas caracteres ASCII (os em inglês). Isso significa que não funcionaria com caracteres como o `á`, como em `Sebastián`.

Para lidar com isso, primeiramente nós convertemos o `username` e o `password` para `bytes`, codificando-os com UTF-8.
