Par exemple, dans l'URL :

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

... les paramètres de requête sont :

* `skip` : avec une valeur de `0`
* `limit` : avec une valeur de `10`

Comme ils font partie de l'URL, ce sont « naturellement » des chaînes de caractères.

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.

JSON solo puede contener strings codificados en UTF-8, así que no puede contener bytes crudos.

Base64 puede codificar datos binarios en strings, pero para hacerlo necesita usar más caracteres que los datos binarios originales, así que normalmente sería menos eficiente que los archivos normales.

Usa base64 solo si definitivamente necesitas incluir datos binarios en JSON y no puedes usar archivos para eso.

an integer value identifying a Unicode code point.
A rune literal is expressed as one or more characters enclosed in single quotes,
as in <code>'x'</code> or <code>'\n'</code>.
Within the quotes, any character may appear except newline and unescaped single
quote. A single quoted character represents the Unicode value
of the character itself,
while multi-character sequences beginning with a backslash encode
values in various formats.
