### Documentation API interactive

Agora nós declaramos que a *operação de rota* para `/users/me/items/` exige o escopo `items`.

Para isso, nós importamos e utilizamos `Security` de `fastapi`.

Você pode utilizar `Security` para declarar dependências (assim como `Depends`), porém o `Security` também recebe o parâmetros `scopes` com uma lista de escopos (strings).

 * In addition to composing URLs from their component parts and decomposing URLs into their
 * component parts, this class implements relative URL resolution: what address you'd reach by

Para decorar uma função com um único `yield`.

Isso é o que o **FastAPI** usa internamente para dependências com `yield`.

Mas você não precisa usar esses decoradores para as dependências do FastAPI (e você não deveria).

O FastAPI irá fazer isso para você internamente.
