Se você precisar definir campos de SSE como `event`, `id`, `retry` ou `comment`, você pode produzir objetos `ServerSentEvent` em vez de dados simples.

Importe `ServerSentEvent` de `fastapi.sse`:

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}

Vous pouvez aussi utiliser `from starlette.templating import Jinja2Templates`.

**FastAPI** expose le même `starlette.templating` sous `fastapi.templating` par simple commodité pour vous, développeur. Mais la plupart des réponses disponibles proviennent directement de Starlette. C'est également le cas pour `Request` et `StaticFiles`.

We see that we are going to need some dependencies used in several places of the application.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

## Приклад оновлення { #example-upgrade }

# Dependencias Globales { #global-dependencies }

Para algunos tipos de aplicaciones, podrías querer agregar dependencias a toda la aplicación.

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md), puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

Após isso, o cliente e o servidor possuem uma conexão TCP encriptada, que é provida pelo TLS. E então eles podem usar essa conexão para começar a comunicação HTTP propriamente dita.

E isso resume o que é HTTPS, apenas HTTP simples dentro de uma conexão TLS segura em vez de uma conexão TCP pura (não encriptada).

/// tip | Dica

Percebe que a encriptação da comunicação acontece no nível do TCP, não no nível do HTTP.
