Abre tu navegador en [http://127.0.0.1:8000/items/5?q=somequery](http://127.0.0.1:8000/items/5?q=somequery).

Verás el response JSON como:

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

Ya creaste una API que:

* Recibe requests HTTP en los _paths_ `/` y `/items/{item_id}`.
* Ambos _paths_ toman _operaciones_ `GET` (también conocidas como métodos HTTP).

Você acabou de criar uma API que:

* Recebe requisições HTTP nos _paths_ `/` e `/items/{item_id}`.

3. `Author` dataclass'ı, `Item` dataclass'larından oluşan bir liste içerir.

4. `Author` dataclass'ı, `response_model` parametresi olarak kullanılır.

5. Request body olarak dataclass'larla birlikte diğer standart type annotation'ları da kullanabilirsiniz.

    Bu örnekte, `Item` dataclass'larından oluşan bir listedir.

6. Burada `items` içeren bir dictionary döndürüyoruz; `items` bir dataclass listesi.
