Der Wert des Pfad-Parameters `item_id` wird Ihrer Funktion als das Argument `item_id` übergeben.

Wenn Sie dieses Beispiel ausführen und auf <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> gehen, sehen Sie als Response:

```JSON
{"item_id":"foo"}
```

* procure o subpacote `routers` (o diretório em `app/routers/`)...
* e dele, importe o submódulo `items` (o arquivo em `app/routers/items.py`) e `users` (o arquivo em `app/routers/users.py`)...

O módulo `items` terá uma variável `router` (`items.router`). Esta é a mesma que criamos no arquivo `app/routers/items.py`, é um objeto `APIRouter`.

E então fazemos o mesmo para o módulo `users`.

Também poderíamos importá-los como:

  // +optional
  optional k8s.io.apimachinery.pkg.apis.meta.v1.ListMeta metadata = 2;

  // items contains each of the included items.
  repeated k8s.io.apimachinery.pkg.apis.meta.v1.PartialObjectMetadata items = 1;
