# Corpo - Atualizações

## Atualização de dados existentes com `PUT`

Para atualizar um item, você pode usar a operação <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

Você pode usar `jsonable_encoder` para converter os dados de entrada em dados que podem ser armazenados como JSON (por exemplo, com um banco de dados NoSQL). Por exemplo, convertendo `datetime` em `str`.

{* ../../docs_src/body_updates/tutorial001_py310.py hl[28:33] *}

`PUT` se usa para recibir datos que deben reemplazar los datos existentes.

### Advertencia sobre el reemplazo

Esto significa que si quieres actualizar el ítem `bar` usando `PUT` con un body que contenga:

```Python
{
    "name": "Barz",
    "price": 3,

        assertEquals("pdf", fileTypeHelper.get("application/pdf"));
        assertEquals("text", fileTypeHelper.get("text/plain"));

        // Test non-existent mimetype returns default value
        assertEquals("others", fileTypeHelper.get("non/existent"));
    }

    public void test_get_withNullMimetype() {
        assertEquals("others", fileTypeHelper.get(null));
    }

        UnknownHostException exception = assertThrows(UnknownHostException.class, () -> {
            nameServiceClient.getNbtByName("NONEXISTENT-FAST-FAIL");
        }, "Should throw UnknownHostException for non-existent NetBIOS name");

        // Verify the exception message indicates name resolution failure
        assertTrue(exception.getMessage().contains("NONEXISTENT") || exception.getMessage().contains("unknown")

    public void test_get_nullProperty() {
        // Test getting non-existent property
        try {
            fessConfig.get("non.existent.property");
            fail("Should throw exception for non-existent property");
        } catch (ConfigPropertyNotFoundException e) {
            // Expected exception
            assertTrue(e.getMessage().contains("non.existent.property"));
        }
    }

        assertEquals(0, mockService.getRegistrationCount());
        assertFalse(mockService.hasRegistration("non-existent"));
        assertFalse(mockService.unregisterWitness("non-existent"));
        assertFalse(mockService.processHeartbeat("non-existent", 1));

        // Test registration with null/empty values
        String regId1 = mockService.registerWitness(null, "192.168.1.100", 1);

	}
