Ce code est utilisable dans votre application, enregistrez les hachages de mots de passe dans votre base de données, etc.

Nous allons repartir d'où nous nous sommes arrêtés dans le chapitre précédent et l'enrichir.

## À propos de JWT { #about-jwt }

JWT signifie « JSON Web Tokens ».

    assert response.status_code == 201, response.text

Wenn Sie in Ihrem Browser eine URL wie:

```
http://127.0.0.1:8000/items/foo-item
```

... öffnen, ohne den benötigten Parameter `needy`, dann erhalten Sie einen Fehler wie den folgenden:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".

FastAPI는 이 반환 타입을 사용하여:

* 반환된 데이터를 **검증**합니다.
    * 데이터가 유효하지 않다면(예: 필드가 누락된 경우), 이는 *여러분의* 앱 코드가 깨져서 의도한 값을 반환하지 못한다는 의미이며, 잘못된 데이터를 반환하는 대신 서버 오류를 반환합니다. 이렇게 하면 여러분과 클라이언트는 기대한 데이터와 데이터 형태를 받는다는 것을 확실히 할 수 있습니다.
* OpenAPI *경로 처리*의 응답에 **JSON Schema**를 추가합니다.
    * 이는 **자동 문서**에서 사용됩니다.
    * 또한 자동 클라이언트 코드 생성 도구에서도 사용됩니다.
* 반환된 데이터를 Pydantic을 사용해 JSON으로 **직렬화**합니다. Pydantic은 **Rust**로 작성되어 있어 **훨씬 더 빠릅니다**.

하지만 가장 중요한 것은:

Wenn Sie gerade erst mit **FastAPI** beginnen, möchten Sie diesen Abschnitt vielleicht überspringen.

## Anwendungsfälle { #use-cases }

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. [`msgpack`](https://msgpack.org/index.html)).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.
