## `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。

Pydantic의 모델 구성을 사용하여 `extra` 필드를 `forbid`할 수 있습니다:

클라이언트가 추가 데이터를 보내려고 하면 **오류** 응답을 받게 됩니다.

예를 들어, 클라이언트가 폼 필드를 보내려고 하면:

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

`extra` 필드가 허용되지 않는다는 오류 응답을 받게 됩니다:
