No exemplo acima eles tem valores padrão de `skip=0` e `limit=10`.

Então, se você for até a URL:

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

Seria o mesmo que ir para:

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

Mas, se por exemplo você for para:

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

Os valores dos parâmetros na sua função serão:

* `skip=20`: Por que você definiu isso na URL

        SocketInputStream sis = new SocketInputStream(in);

        // Try to skip more than available
        // Skip uses read internally, which may throw IOException when it tries to read the next header
        try {
            long skipped = sis.skip(10);
            // If it doesn't throw, it should only skip what's available
            assertEquals(3, skipped);
        } catch (IOException e) {

	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 BenchmarkMarshalMsgDailyAllTierStats(b *testing.B) {
	v := DailyAllTierStats{}
	b.ReportAllocs()
	b.ResetTimer()

In the example above they have default values of `skip=0` and `limit=10`.

So, going to the URL:

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

would be the same as going to:

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

But if you go to, for example:

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

The parameter values in your function will be:

* `skip=20`: because you set it in the URL

      // drop second byte of compression offset
      source.skip(1)

      while (length > 0) {
        // skip each part of the domain name
        source.skip(length.toLong())

  }

쿼리 매개변수는 경로에서 고정된 부분이 아니기 때문에 선택적일 수 있고 기본값을 가질 수 있습니다.

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

                            return 0;
                          }
                        };
                      }
                    })
                .iterator());
    assertEquals(0, multi.skip(-1));
    assertEquals(0, multi.skip(-1));
    assertEquals(0, multi.skip(0));
    ByteStreams.skipFully(multi, 20);
