async def read_user_item(
    item_id: str, needy: str, skip: int = 0, limit: int | None = None
):
    item = {"item_id": item_id, "needy": needy, "skip": skip, "limit": limit}

Dans l'exemple ci-dessus, ils ont des valeurs par défaut qui sont `skip=0` et `limit=10`.

Donc, accéder à l'URL :

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

serait équivalent à accéder à l'URL :

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

Mais si vous accédez à, par exemple :

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

Les valeurs des paramètres de votre fonction seront :

    if (length < 0) {
      // compressed name pointer, first two bits are 1
      // drop second byte of compression offset
      source.skip(1)
    } else {
      while (length > 0) {
        // skip each part of the domain name
        source.skip(length.toLong())
        length = source.readByte().toInt()
      }
    }
  }

    [
        (
            "/items/",
            [{"item_name": "Foo"}, {"item_name": "Bar"}, {"item_name": "Baz"}],
        ),
        (
            "/items/?skip=1",
            [{"item_name": "Bar"}, {"item_name": "Baz"}],
        ),
        (
            "/items/?skip=1&limit=1",
            [{"item_name": "Bar"}],
        ),
    ],
)
def test_read_user_item(client: TestClient, path, expected_json):

В примере выше значения по умолчанию равны `skip=0` и `limit=10`.

Таким образом, результат перехода по URL-адресу:

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

будет таким же, как если перейти используя параметры по умолчанию:

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

Но если вы введёте, например:

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

Значения параметров в вашей функции будут:

	if err != nil {
		t.Fatal(err)
	}
	if len(left) > 0 {
		t.Errorf("%d bytes left over after UnmarshalMsg(): %q", len(left), left)
	}

	left, err = msgp.Skip(bts)
	if err != nil {
		t.Fatal(err)
	}
	if len(left) > 0 {
		t.Errorf("%d bytes left over after Skip(): %q", len(left), left)
	}
}

func BenchmarkMarshalMsgAccElem(b *testing.B) {
	v := AccElem{}
	b.ReportAllocs()
	b.ResetTimer()

	if err != nil {
		t.Fatal(err)
	}
	if len(left) > 0 {
		t.Errorf("%d bytes left over after UnmarshalMsg(): %q", len(left), left)
	}

	left, err = msgp.Skip(bts)
	if err != nil {
		t.Fatal(err)
	}
	if len(left) > 0 {
		t.Errorf("%d bytes left over after Skip(): %q", len(left), left)
	}
}

func BenchmarkMarshalMsgBatchJobExpire(b *testing.B) {
	v := BatchJobExpire{}
	b.ReportAllocs()
	b.ResetTimer()
