Por ejemplo, como en el modelo `Image` tenemos un campo `url`, podemos declararlo como una instance de `HttpUrl` de Pydantic en lugar de un `str`:

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

El string será verificado para ser una URL válida, y documentado en JSON Schema / OpenAPI como tal.

You can send (and receive) many messages:

And all of them will use the same WebSocket connection.

## Using `Depends` and others { #using-depends-and-others }

In WebSocket endpoints you can import from `fastapi` and use:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`
