Também, a melhor abordagem era usar padrões já existentes.

Então, antes mesmo de começar a codificar o **FastAPI**, eu investi vários meses estudando as especificações do OpenAPI, JSON Schema, OAuth2 etc. Entendendo suas relações, sobreposições e diferenças.

## Design { #design }

Para atualizar um item, você pode usar a operação [HTTP `PUT`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT).

Você pode usar `jsonable_encoder` para converter os dados de entrada em dados que podem ser armazenados como JSON (por exemplo, com um banco de dados NoSQL). Por exemplo, convertendo `datetime` em `str`.

{* ../../docs_src/body_updates/tutorial001_py310.py hl[28:33] *}

`PUT` é usado para receber dados que devem substituir os dados existentes.

```txt
Hello, World from Flask!
```

Y si vas a [http://localhost:8000/v2](http://localhost:8000/v2) verás el response de FastAPI:

```JSON
{
    "message": "Hello World"
}

          set +x
          VAULT_TOKEN=$(vault write -field=token auth/approle/login role_id=$VAULT_ROLE_ID secret_id=$VAULT_SECRET_ID)
          export VAULT_TOKEN
          export data=$(vault read -format=json secret/elasticsearch-ci/azure_thirdparty_test_creds)
          export azure_storage_account=$(echo $data | jq -r .data.account_id)
          export azure_storage_key=$(echo $data | jq -r .data.account_key)

This is an "advanced" feature.

If you are just starting with **FastAPI** you might want to skip this section.

## Use cases { #use-cases }

Some use cases include:

* Converting non-JSON request bodies to JSON (e.g. [`msgpack`](https://msgpack.org/index.html)).
* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

De plus, la meilleure approche était d'utiliser des normes déjà existantes.

Ainsi, avant même de commencer à coder **FastAPI**, j'ai passé plusieurs mois à étudier les spécifications d'OpenAPI, JSON Schema, OAuth2, etc. Comprendre leurs relations, leurs similarités et leurs différences.

## Conception { #design }

Vous pouvez utiliser le `jsonable_encoder` pour convertir les données d’entrée en données pouvant être stockées au format JSON (par exemple, avec une base de données NoSQL). Par exemple, convertir `datetime` en `str`.
