Vous obtenez alors cette réponse <abbr title="JavaScript Object Notation">JSON</abbr> :

```JSON
{"item_id": 5, "q": "somequery"}
```

Vous venez de créer une API qui :

* Reçoit les requêtes HTTP pour les _chemins_ `/` et `/items/{item_id}`.

</details>

### 檢查

使用瀏覽器開啟 <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>。

你將會看到以下的 JSON 回應：

```JSON
{"item_id": 5, "q": "somequery"}
```

你已經建立了一個具有以下功能的 API：

- 透過路徑 `/` 和 `/items/{item_id}` 接受 HTTP 請求。
- 以上路經都接受 `GET` 請求（也被稱為 HTTP _方法_）。
- 路徑 `/items/{item_id}` 有一個 `int` 型別的 `item_id` 參數。
