The value of the path parameter `item_id` will be passed to your function as the argument `item_id`.

So, if you run this example and go to [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo), you will see a response of:

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

Se você não selecionar nenhum escopo, você terá "autenticado", mas quando você tentar acessar `/users/me/` ou `/users/me/items/`, você vai obter um erro dizendo que você não possui as permissões necessárias. Você ainda poderá acessar `/status/`.

E se você selecionar o escopo `me`, mas não o escopo `items`, você poderá acessar `/users/me/`, mas não `/users/me/items/`.
