* verifica che la richiesta abbia un attributo obbligatorio `name` e che sia di tipo `str`.
    * verifica che la richiesta abbia un attributo obbligatorio `price` e che sia di tipo `float`.
    * verifica che la richiesta abbia un attributo opzionale `is_offer` e che sia di tipo `bool`, se presente.
    * Tutto questo funzionerebbe anche con oggetti JSON più complessi.

Existem utilitários para configurá-lo facilmente que você pode usar diretamente em sua aplicação **FastAPI** (fornecidos pelo Starlette).

Stellen Sie zunächst sicher, dass Sie Ihre Umgebung wie oben beschrieben einrichten, was alles Benötigte installiert.

### Dokumentation live

Während der lokalen Entwicklung gibt es ein Skript, das die Site erstellt, auf Änderungen prüft und direkt neu lädt (Live Reload):

<div class="termy">

```console
$ python ./scripts/docs.py live

<span style="color: green;">[INFO]</span> Serving on http://127.0.0.1:8008

```

</div>

这样会对每一种语言构建一个独立的文档站点，并最终把这些站点全部打包输出到 `./site/` 目录。



然后你可以使用命令 `serve` 来运行生成的站点：

<div class="termy">

```console
// Use the command "serve" after running "build-all"
$ python ./scripts/docs.py serve

Warning: this is a very simple server. For development, use mkdocs serve instead.
This is here only to preview a site with translations already built.

Requests a un design très simple et intuitif, il est très facile à utiliser, avec des valeurs par défaut raisonnables, tout en étant très puissant et personnalisable.

C'est pourquoi, comme le dit le site officiel :

> Requests est l'un des packages Python les plus téléchargés de tous les temps

La façon dont vous l'utilisez est très simple. Par exemple, pour faire une requête `GET`, vous devez écrire :
