### Kiểm tra

Mở trình duyệt của bạn tại <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>.

Bạn sẽ thấy một JSON response:

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

Bạn đã sẵn sàng để tạo một API như sau:

* Nhận HTTP request với _đường dẫn_ `/` và `/items/{item_id}`.

</details>

### 检查

使用浏览器访问 <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>。

你将会看到如下 JSON 响应：

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

你已经创建了一个具有以下功能的 API：

* 通过 _路径_ `/` 和 `/items/{item_id}` 接受 HTTP 请求。
* 以上 _路径_ 都接受 `GET` 操作（也被称为 HTTP _方法_）。
* `/items/{item_id}` _路径_ 有一个 _路径参数_ `item_id` 并且应该为 `int` 类型。

In this case, if you go to:

```
http://127.0.0.1:8000/items/foo?short=1
```

or

```
http://127.0.0.1:8000/items/foo?short=True
```

or

```
http://127.0.0.1:8000/items/foo?short=true
```

or

```
http://127.0.0.1:8000/items/foo?short=on
```

or

```
http://127.0.0.1:8000/items/foo?short=yes
```
