Or you might have any other way to communicate with the WebSocket endpoint.

But for this example, we'll use a very simple HTML document with some JavaScript, all inside a long string.

This, of course, is not optimal and you wouldn't use it for production.

In production you would have one of the options above.

* Documentarlo como tal en el esquema de OpenAPI (y por lo tanto, en las interfaces de usuario):

/// note | Nota

Algunos códigos de response (ver la siguiente sección) indican que el response no tiene un body.

FastAPI sabe esto, y producirá documentación OpenAPI que establece que no hay un response body.

   * thus a motivated caller may be able to expose the reference to another thread that would then
   * call cancel() and be unable to cancel the delegate.
   * There are a number of ways to solve this, none of which are very pretty, and it is currently
   * believed to be a purely theoretical problem (since the other actions should supply sufficient
   * write-barriers).

## Versões disponíveis

Você pode ver as versões disponíveis (por exemplo, para verificar qual é a versão atual) em [Release Notes](../release-notes.md){.internal-link target=\_blank}.

## Sobre versões

The steps below show how to use this notification target in `namespace` format. The other format is very similar and is omitted for brevity.

### Step 1: Ensure Elasticsearch minimum requirements are met

        Smb2LeaseKey key = leaseManager.requestLease(path, requestedState);
        assertNotNull(leaseManager.getLease(key));

        // Wait a bit and then cleanup with a very short expiration time
        Thread.sleep(10);
        int cleaned = leaseManager.cleanupExpiredLeases(1); // 1ms expiration

        assertEquals(1, cleaned);
        assertNull(leaseManager.getLease(key));
    }

You can also read more about them in the <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia for Environment Variable</a>.

In many cases it's not very obvious how environment variables would be useful and applicable right away. But they keep showing up in many different scenarios when you are developing, so it's good to know about them.

It is based on <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, which in turn is designed based on Requests, so it's very familiar and intuitive.

With it, you can use <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> directly with **FastAPI**.
