### Étape 5 : retourner le contenu

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

Vous pouvez retourner un dictionnaire (`dict`), une liste (`list`), des valeurs seules comme des chaines de caractères (`str`) et des entiers (`int`), etc.

Vous pouvez aussi retourner des models **Pydantic** (qui seront détaillés plus tard).

}

/// tip | Consejo

Cuando lanzas un `HTTPException`, puedes pasar cualquier valor que pueda convertirse a JSON como el parámetro `detail`, no solo `str`.

Podrías pasar un `dict`, un `list`, etc.

Son manejados automáticamente por **FastAPI** y convertidos a JSON.

            validator.validatePath("\\share\\other\\file.txt");
            fail("Should block non-whitelisted path");
        } catch (SmbException e) {
            assertTrue(e.getMessage().contains("not in allowed list"));
        }
    }

    @Test
    public void testBlacklistPriority() throws Exception {
        // Add to both blacklist and whitelist
        validator.addToBlacklist("\\share\\test");

}
```

/// tip | Dica

Quando você lançar um `HTTPException`, você pode passar qualquer valor convertível em JSON como parâmetro de `detail`, e não apenas `str`.

Você pode passar um `dict` ou um `list`, etc.
Esses tipos de dados são manipulados automaticamente pelo **FastAPI** e convertidos em JSON.
