Например, в этом URL-адресе:

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

...параметры запроса такие:

* `skip`: со значением `0`
* `limit`: со значением `10`

Будучи частью URL-адреса, они "по умолчанию" являются строками.

	// Limit the number of returned objects if > 0.

	// Leave empty to not check disk ID.
	DiskID string

위 예에서 `skip=0`과 `limit=10`은 기본값을 갖고 있습니다.

그러므로 URL로 이동하는 것은:

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

아래로 이동하는 것과 같습니다:

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

하지만 가령 아래로 이동한 경우:

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

함수의 매개변수 값은 아래가 됩니다:

* `skip=20`: URL에서 지정했기 때문입니다
* `limit=10`: 기본값이기 때문입니다
