In many cases, when you use regular Pydantic models without customizations, you will be able to automate most of the process of migrating from Pydantic v1 to Pydantic v2.

You can use <a href="https://github.com/pydantic/bump-pydantic" class="external-link" target="_blank">`bump-pydantic`</a> from the same Pydantic team.

### `response` の前後

*path operation* が `request` を受け取る前に、 `request` とともに実行されるコードを追加できます。

また `response` が生成された後、それを返す前にも追加できます。

例えば、リクエストの処理とレスポンスの生成にかかった秒数を含むカスタムヘッダー `X-Process-Time` を追加できます:

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}
