Ele deve parecer exatamente como uma *operação de rota* normal do FastAPI:

* Ele provavelmente deveria ter uma declaração do corpo que deveria receber, por exemplo. `body: InvoiceEvent`.
* E também deveria ter uma declaração de um código de status de resposta, por exemplo. `response_model=InvoiceEventReceived`.

{* ../../docs_src/openapi_callbacks/tutorial001.py hl[16:18,21:22,28:32] *}

    * Siccome il parametro `q` è dichiarato con `= None`, è opzionale.
    * Senza il `None` sarebbe stato obbligatorio (come per il body della richiesta `PUT`).
* Per le richieste `PUT` su `/items/{item_id}`, leggerà il body come JSON, questo comprende:
    * verifica che la richiesta abbia un attributo obbligatorio `name` e che sia di tipo `str`.

`extra` 필드가 허용되지 않는다는 오류 응답을 받게 됩니다:

Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

3. The `Author` dataclass includes a list of `Item` dataclasses.

4. The `Author` dataclass is used as the `response_model` parameter.

5. You can use other standard type annotations with dataclasses as the request body.

    In this case, it's a list of `Item` dataclasses.

6. Here we are returning a dictionary that contains `items` which is a list of dataclasses.
