クエリパラメータはパスの固定部分ではないので、オプショナルとしたり、デフォルト値をもつことができます。

上述の例では、`skip=0` と `limit=10` というデフォルト値を持っています。

したがって、以下のURLにアクセスすることは:

```
http://127.0.0.1:8000/items/
```

以下のURLにアクセスすることと同等になります:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

しかし、例えば、以下にアクセスすると:

```
http://127.0.0.1:8000/items/?skip=20
```

関数内のパラメータの値は以下の様になります:

* `skip=20`: URL内にセットしたため
* `limit=10`: デフォルト値
