### 확인하기

브라우저로 <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>를 열어보십시오.

아래의 JSON 응답을 볼 수 있습니다:

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

여러분은 벌써 API를 만들었습니다:

* _경로_ `/` 및 `/items/{item_id}`에서 HTTP 요청 받기.
* 두 _경로_ 모두 `GET` 연산(HTTP _메소드_ 로 알려진)을 받습니다.
* _경로_ `/items/{item_id}`는 _경로 매개변수_ `int`형 이어야 하는 `item_id`를 가지고 있습니다.
