Cela fera de `tags` une liste, bien que le type des éléments de la liste ne soit pas déclaré.

## Champs de liste avec paramètre de type { #list-fields-with-type-parameter }

Mais Python a une manière spécifique de déclarer des listes avec des types internes, ou « paramètres de type » :

### Déclarer une `list` avec un paramètre de type { #declare-a-list-with-a-type-parameter }

Executing `fastapi run` starts FastAPI in production mode.

proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.

///

The docs UI would also need the OpenAPI schema to declare that this API `server` is located at `/api/v1` (behind the proxy). For example:

Bunu sağlayabilmek için `:80`-backend’in bir "allowed origins" listesi olmalıdır.

Bu örnekte `:8080`-frontend’in doğru çalışması için listede `http://localhost:8080` bulunmalıdır.

## Wildcard'lar { #wildcards }

Listeyi `"*"` (bir "wildcard") olarak tanımlayıp, hepsine izin verildiğini söylemek de mümkündür.
