UserInDB(**user_dict)
```

dann ist das ungefähr äquivalent zu:

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

Oder, präziser, `user_dict` wird direkt verwendet, welche Werte es auch immer haben mag:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],

  /**
   * The decoded username, or an empty string if none is present.
   *
   * | URL                              | `username()` |
   * | :------------------------------- | :----------- |
   * | `http://host/`                   | `""`         |
   * | `http://username@host/`          | `"username"` |
   * | `http://username:password@host/` | `"username"` |
   * | `http://a%20b:c%20d@host/`       | `"a b"`      |

        // Then

Así que, revisémoslo desde ese punto de vista simplificado:

* El usuario escribe el `username` y `password` en el frontend, y presiona `Enter`.
* El frontend (ejecutándose en el navegador del usuario) envía ese `username` y `password` a una URL específica en nuestra API (declarada con `tokenUrl="token"`).
* La API verifica ese `username` y `password`, y responde con un "token" (no hemos implementado nada de esto aún).

예를 들어, OAuth2 사양을 사용할 수 있는 방법 중 하나("패스워드 플로우"라고 함)로 `username`과 `password`를 폼 필드로 보내야 합니다.

<abbr title="specification">사양</abbr>에서는 필드 이름이 `username` 및 `password`로 정확하게 명명되어야 하고, JSON이 아닌 폼 필드로 전송해야 합니다.

`Form`을 사용하면 유효성 검사, 예제, 별칭(예: `username` 대신 `user-name`) 등을 포함하여 `Body`(및 `Query`, `Path`, `Cookie`)와 동일한 구성을 선언할 수 있습니다.
