## Mais informações { #more-info }

Para aprender mais sobre as opções, verifique a documentação do Starlette para:

* <a href="https://www.starlette.dev/websockets/" class="external-link" target="_blank">A classe `WebSocket`</a>.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

In these cases, you would normally return an **HTTP status code** in the range of **400** (from 400 to 499).

### `startup` and `shutdown` together { #startup-and-shutdown-together }

There's a high chance that the logic for your *startup* and *shutdown* is connected, you might want to start something and then finish it, acquire a resource and then release it, etc.

Doing that in separated functions that don't share logic or variables together is more difficult as you would need to store values in global variables or similar tricks.

With any of the methods above it would look like this in the `/docs`:

<img src="/img/tutorial/body-fields/image01.png">

### `Body` with multiple `examples` { #body-with-multiple-examples }

You can of course also pass multiple `examples`:

{* ../../docs_src/schema_extra_example/tutorial004_an_py310.py hl[23:38] *}

When you do this, the examples will be part of the internal **JSON Schema** for that body data.

De esta manera, en muchos casos puedes aprender sobre contenedores y Docker y reutilizar ese conocimiento con muchas herramientas y componentes diferentes.

		subrouter.Methods(http.MethodPost).Path("/v1/runlock").HandlerFunc(lockServer.RUnlockHandler)
		subrouter.Methods(http.MethodPost).Path("/v1/force-unlock").HandlerFunc(lockServer.ForceUnlockHandler)

		nodes[i] = httptest.NewServer(router)
