## Un `StreamingResponse` con `yield` { #a-streamingresponse-with-yield }

Si declaras un `response_class=StreamingResponse` en tu *path operation function*, puedes usar `yield` para enviar cada bloque de datos a su vez.

### Feature

- Add paths section to kubelet statusz endpoint ([#133239](https://github.com/kubernetes/kubernetes/pull/133239), [@Peac36](https://github.com/Peac36)) [SIG Node]

    void testSetDeviceState() {
        response.deviceState = 0x8000;
        assertEquals(0x8000, response.deviceState);
    }

    @Test
    void testSetAction() {
        response.action = 2;
        assertEquals(2, response.action);
    }

    @Test
    void testSetServerFid() {
        response.serverFid = 456;
        assertEquals(456, response.serverFid);
    }

    @Test
    void testToString() {

Logo, a seção com:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...irá gerar um link para a mesma URL que será tratada pela *path operation function* `read_item(id=id)`.

Por exemplo, com um ID de `42`, isso renderizará:

```html

    String[] DOS_ERROR_MESSAGES = { "The operation completed successfully.", "Incorrect function.", "Incorrect function.",
            "The system cannot find the file specified.", "Bad password.", "The system cannot find the path specified.", "reserved",
            "The client does not have the necessary access rights to perform the requested function.", "Access is denied.",

     */
    String[] DOS_ERROR_MESSAGES = { "The operation completed successfully.", "Incorrect function.", "Incorrect function.",
            "The system cannot find the file specified.", "Bad password.", "The system cannot find the path specified.", "reserved",
            "The client does not have the necessary access rights to perform the requested function.", "Access is denied.",

Vous pouvez ensuite créer une autre fonction de dépendance (un « dependable ») qui, en même temps, déclare sa propre dépendance (elle est donc aussi un « dependant ») :

Concentrons-nous sur les paramètres déclarés :
