It declares an optional query parameter `q` as a `str`, and then it just returns it.

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

## Second dependency, "dependable" and "dependant"

# CORS (オリジン間リソース共有)

<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS" class="external-link" target="_blank">CORSまたは「オリジン間リソース共有」</a> は、ブラウザで実行されているフロントエンドにバックエンドと通信するJavaScriptコードがあり、そのバックエンドがフロントエンドとは異なる「オリジン」にある状況を指します。

## オリジン

オリジンはプロトコル (`http`、`https`) とドメイン (`myapp.com`、`localhost`、`localhost.tiangolo.com`) とポート (`80`、`443`、`8080`) の組み合わせです。

したがって、以下はすべて異なるオリジンです:

* `http://localhost`
* `https://localhost`
