用浏览器打开 [http://127.0.0.1:8000/items/5?q=somequery](http://127.0.0.1:8000/items/5?q=somequery)。

你会看到如下 JSON 响应：

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

你已经创建了一个 API，它可以：

* 在路径 `/` 和 `/items/{item_id}` 接收 HTTP 请求。
* 以上两个路径都接受 `GET` 操作（也称为 HTTP 方法）。
* 路径 `/items/{item_id}` 有一个应为 `int` 的路径参数 `item_id`。
* 路径 `/items/{item_id}` 有一个可选的 `str` 类型查询参数 `q`。
