## Simple and Powerful { #simple-and-powerful }

Although the hierarchical dependency injection system is very simple to define and use, it's still very powerful.

Requestsは非常にシンプルかつ直感的なデザインで使いやすく、適切なデフォルト値を設定しています。しかし同時に、非常に強力でカスタマイズも可能です。

公式サイトで以下のように言われているのは、それが理由です。

> Requestsは今までで最もダウンロードされたPythonパッケージである

使い方はとても簡単です。例えば、`GET`リクエストを実行するには、このように書けば良いです:

```Python
response = requests.get("http://example.com/some/url")
```

対応するFastAPIのパスオペレーションはこのようになります:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

//
// Newer API response with policy timestamps is returned with query parameter
// `v=2` like:
//
// GET /minio/admin/v3/info-canned-policy?name={policyName}&v=2
//
// The newer API will eventually become the default (and only) one. The older
// response is to return only the policy JSON. The newer response returns
