## 추가 쿼리 매개변수 금지

몇몇의 특이한 경우에 (흔치 않지만), 허용할 쿼리 매개변수를 **제한**해야할 수 있습니다.

Pydantic 모델 설정에서 `extra` 필드를 `forbid` 로 설정할 수 있습니다.

{* ../../docs_src/query_param_models/tutorial002_an_py310.py hl[10] *}

만약 클라이언트가 쿼리 매개변수로 **추가적인** 데이터를 보내려고 하면, 클라이언트는 **에러** 응답을 받게 됩니다.

        final long original = 0x1122334455667788L;
        NdrHyper hyper = new NdrHyper(original);
        // Create buffer with extra space for alignment
        NdrBuffer buf = new NdrBuffer(new byte[16], 0);
        hyper.encode(buf);
        // Reset buffer position for decoding
        buf.reset();
        NdrHyper decoded = new NdrHyper(0);

		Method: Deflate,
		Extra:  []byte(ts.Format(time.RFC3339Nano)), // missing tag and len, but Extra is best-effort parsing
	}

	testValidHeader(&h, t)
}

func TestHeaderTooShort(t *testing.T) {
	h := FileHeader{
		Name:   "foo.txt",
		Method: Deflate,
		Extra:  []byte{zip64ExtraID}, // missing size and second half of tag, but Extra is best-effort parsing
	}

## Запрет дополнительных cookies { #forbid-extra-cookies }

В некоторых случаях (не особо часто встречающихся) вам может понадобиться **ограничить** cookies, которые вы хотите получать.

Luego declara los parámetros de header usando la misma estructura que con `Path`, `Query` y `Cookie`.

Puedes definir el valor por defecto así como toda la validación extra o los parámetros de anotaciones:
