To keep the Groovy DSL ergonomic, we generate methods as necessary from the non-Groovy equivalents.

Doing this provides the following specific benefits:
- **Reduce the API surface** - We no longer need to maintain two methods.
- **Consistency** - All languages have consistent access to the same APIs and ergonomics in the DSL.

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

## `username` とデータ構造の検証 { #verify-the-username-and-data-shape }

`username` を取得できていることを確認し、スコープを取り出します。

そして、そのデータを Pydantic モデルで検証します（`ValidationError` 例外を捕捉）。JWT トークンの読み取りや Pydantic によるデータ検証でエラーが発生した場合は、先ほど作成した `HTTPException` を送出します。

そのために、Pydantic モデル `TokenData` に新しいプロパティ `scopes` を追加します。

Pydantic でデータを検証することで、例えばスコープは `str` の `list`、`username` は `str` といった、正確な型になっていることを保証できます。
