By contributing to the BVLC/caffe repository through pull-request, comment,

{* ../../docs_src/first_steps/tutorial001.py hl[7] *}

This is a Python function.

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:

  "disabled": false
}
```

If you open the developer tools, you could see how the data sent only includes the token, the password is only sent in the first request to authenticate the user and get that access token, but not afterwards:

/// note

Notice the header `Authorization`, with a value that starts with `Bearer `.

# リクエストボディ

クライアント (ブラウザなど) からAPIにデータを送信する必要があるとき、データを **リクエストボディ (request body)** として送ります。

**リクエスト** ボディはクライアントによってAPIへ送られます。**レスポンス** ボディはAPIがクライアントに送るデータです。

APIはほとんどの場合 **レスポンス** ボディを送らなければなりません。しかし、クライアントは必ずしも **リクエスト** ボディを送らなければいけないわけではありません。

**リクエスト** ボディを宣言するために <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> モデルを使用します。そして、その全てのパワーとメリットを利用します。
