Yani, aşağıdaki bağlantıya gitmek:

```
http://127.0.0.1:8000/items/
```

şu adrese gitmek ile aynı etkiye sahiptir:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Ancak, mesela şöyle bir adresi ziyaret ederseniz:

```
http://127.0.0.1:8000/items/?skip=20
```

Fonksiyonunuzdaki parametre değerleri aşağıdaki gibi olacaktır:

* `skip=20`: çünkü bağlantıda böyle tanımlandı.

`Cookie` es una clase "hermana" de `Path` y `Query`. También hereda de la misma clase común `Param`.

Pero recuerda que cuando importas `Query`, `Path`, `Cookie`  y otros de `fastapi`, en realidad son funciones que devuelven clases especiales.
