## ユーザーの取得

`get_current_user` は作成した（偽物の）ユーティリティ関数を使って、 `str` としてトークンを受け取り、先ほどのPydanticの `User` モデルを返却します:

{* ../../docs_src/security/tutorial002.py hl[19:22,26:27] *}

## 現在のユーザーの注入

ですので、 `get_current_user` に対して同様に *path operation* の中で `Depends` を利用できます。

{* ../../docs_src/security/tutorial002.py hl[31] *}

Pydanticモデルの `User` として、 `current_user` の型を宣言することに注意してください。

その関数の中ですべての入力補完や型チェックを行う際に役に立ちます。
