## Importe `Field` { #import-field }

Primeiro, você tem que importá-lo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | Atenção

Note que `Field` é importado diretamente do `pydantic`, não do `fastapi` como todo o resto (`Query`, `Path`, `Body`, etc).

///

        Field[] fields = SecurityInfo.class.getDeclaredFields();

        for (Field field : fields) {
            int modifiers = field.getModifiers();
            assertTrue(Modifier.isPublic(modifiers), "Field " + field.getName() + " should be public");
            assertTrue(Modifier.isStatic(modifiers), "Field " + field.getName() + " should be static");

        }
    }

    // Helper method to set private dialectIndex field using reflection
    private void setDialectIndex(SmbComNegotiateResponse response, int dialectIndex) {
        try {
            Field field = response.getClass().getDeclaredField("dialectIndex");
            field.setAccessible(true);
            field.set(response, dialectIndex);
        } catch (Exception e) {

## Імпорт `Field`

Спочатку вам потрібно імпортувати це:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning

Зверніть увагу, що `Field` імпортується прямо з `pydantic`, а не з `fastapi`, як всі інші (`Query`, `Path`, `Body` тощо).
