パスパラメータ `item_id` の値は、引数 `item_id` として関数に渡されます。

しがたって、この例を実行して <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> にアクセスすると、次のレスポンスが表示されます。

```JSON
{"item_id":"foo"}
```

## パスパラメータと型

標準のPythonの型アノテーションを使用して、関数内のパスパラメータの型を宣言できます:

```Python hl_lines="7"
