# WebSockets { #websockets }

You can use [WebSockets](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API) with **FastAPI**.

## Install `websockets` { #install-websockets }

Make sure you create a [virtual environment](../virtual-environments.md), activate it, and install `websockets` (a Python library that makes it easy to use the "WebSocket" protocol):

<div class="termy">

```console
$ pip install websockets

---> 100%
```

        // Test with value parameters
        configParameters = "field.value.type=document\nfield.value.lang=en";
        result = ParameterUtil.createConfigParameterMap(configParameters);
        assertEquals(2, result.get(ConfigName.VALUE).size());
        assertEquals("document", result.get(ConfigName.VALUE).get("type"));
        assertEquals("en", result.get(ConfigName.VALUE).get("lang"));

        // Test with script parameters

        source.put(FieldNames.TAGS, Arrays.asList("tag1"));
        source.put(FieldNames.ROLES, Arrays.asList("role1"));
        source.put(FieldNames.LANGUAGES, Arrays.asList("en"));
        source.put(FieldNames.KINDS, Arrays.asList("query"));
        source.put(FieldNames.TIMESTAMP, System.currentTimeMillis());

        SuggestItem item = SuggestItem.parseSource(source);

* その後、`response` を返す前にさらに `response` を変更することもできます。

## Technical Details { #technical-details }

Just a technical detail for the curious nerds. 🤓

Underneath, in the ASGI technical specification, this is part of the [Lifespan Protocol](https://asgi.readthedocs.io/en/latest/specs/lifespan.html), and it defines events called `startup` and `shutdown`.

/// info

You can read more about the Starlette `lifespan` handlers in [Starlette's  Lifespan' docs](https://www.starlette.dev/lifespan/).

 * This can be a problem if using DFS in it's default configuration as that still returns referrals in short form.
 * See <a href="https://support.microsoft.com/en-us/kb/244380">KB-244380</a> for compatible server configuration.
 * See {@link jcifs.Configuration#isDfsConvertToFQDN()} for a workaround.
