## Verificar el `username` y la forma de los datos { #verify-the-username-and-data-shape }

Verificamos que obtenemos un `username`, y extraemos los scopes.

And multiple processes normally **don't share any memory**. This means that each running process has its own things, variables, and memory. And if you are consuming a large amount of memory in your code, **each process** will consume an equivalent amount of memory.

## `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。
