## Interdire les champs de formulaire supplémentaires { #forbid-extra-form-fields }

Dans certains cas d'utilisation particuliers (probablement peu courants), vous pourriez vouloir **restreindre** les champs de formulaire à ceux déclarés dans le modèle Pydantic, et **interdire** tout champ **supplémentaire**.

        SMBUtil.writeInt2(4, buffer, 0);
        // Write reserved field (any value is acceptable)
        buffer[2] = (byte) byte2;
        buffer[3] = (byte) byte3;

        // When
        int bytesRead = response.readBytesWireFormat(buffer, 0);

        // Then - should still read 4 bytes regardless of reserved field value
        assertEquals(4, bytesRead);
    }

    @Test

            verify(mockTree).send(cap.capture(), any(RequestParam.class));
            Smb2ReadRequest req = cap.getValue();

            // Reflectively inspect the private 'offset' field to assert it used the advanced fp
            Field offField = Smb2ReadRequest.class.getDeclaredField("offset");
            offField.setAccessible(true);
            long offVal = offField.getLong(req);

## Proibir Campos Extras de Formulários { #forbid-extra-form-fields }

Em alguns casos de uso especiais (provavelmente não muito comum), você pode desejar **restringir** os campos do formulário para aceitar apenas os declarados no modelo Pydantic. E **proibir** qualquer campo **extra**.
