Hacer eso en funciones separadas que no comparten lógica o variables juntas es más difícil ya que necesitarías almacenar valores en variables globales o trucos similares.

Debido a eso, ahora se recomienda en su lugar usar el `lifespan` como se explicó arriba.

## Detalles Técnicos { #technical-details }

Solo un detalle técnico para los nerds curiosos. 🤓

Ainsi, avant même de commencer à coder **FastAPI**, j'ai passé plusieurs mois à étudier les spécifications d'OpenAPI, JSON Schema, OAuth2, etc. Comprendre leurs relations, leurs similarités et leurs différences.

## Conception

Ensuite, j'ai passé du temps à concevoir l'"API" de développeur que je voulais avoir en tant qu'utilisateur (en tant que développeur utilisant FastAPI).

* `swagger_css_url`: the URL where the HTML for your Swagger UI docs can get the **CSS** file. This is the custom CDN URL.

And similarly for ReDoc...

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[2:6,11:19,22:24,27:33] *}

/// tip

The *path operation* for `swagger_ui_redirect` is a helper for when you use OAuth2.

// RefreshHandler - refresh the current lock

	// Add a timeout similar to what we expect upstream.
	ctx, cancel := context.WithTimeout(context.Background(), dsync.DefaultTimeouts.RefreshCall)
	defer cancel()

	resp := lockRPCRefresh.NewResponse()
	refreshed, err := l.ll.Refresh(ctx, *args)

Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).

Each file is a list of API features, one per line.

go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.

except.txt lists features that may disappear without breaking true
compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"
