При створенні API, "шлях" є основним способом розділення "завдань" і "ресурсів".
#### Operation

"Операція" (operation) тут означає один з "методів" HTTP.

Один з:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...та більш екзотичних:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

If you want to read more about these encodings and form fields, head to the <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST" class="external-link" target="_blank"><abbr title="Mozilla Developer Network">MDN</abbr> web docs for <code>POST</code></a>.

# 응답 모델

어떤 *경로 작동*이든 매개변수 `response_model`를 사용하여 응답을 위한 모델을 선언할 수 있습니다:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 기타.

```Python hl_lines="17"
{!../../docs_src/response_model/tutorial001.py!}
```

/// note | "참고"

`response_model`은 "데코레이터" 메소드(`get`, `post`, 등)의 매개변수입니다. 모든 매개변수들과 본문(body)처럼 *경로 작동 함수*가 아닙니다.

#### Operation

„Operation“ bezieht sich hier auf eine der HTTP-„Methoden“.

Eine von diesen:

* `POST`
* `GET`
* `PUT`
* `DELETE`

... und die etwas Exotischeren:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`
