### Verifique a documentação { #check-the-docs }

Como os valores disponíveis para o *parâmetro de path* são predefinidos, a documentação interativa pode mostrá-los de forma agradável:

### Trabalhando com *enumerações* do Python { #working-with-python-enumerations }

Esses headers preservam informações sobre a requisição original que, de outra forma, seriam perdidas:

* X-Forwarded-For: o endereço IP original do cliente
* X-Forwarded-Proto: o protocolo original (`https`)
* X-Forwarded-Host: o host original (`mysuperapp.com`)

Quando a **CLI do FastAPI** é configurada com `--forwarded-allow-ips`, ela confia nesses headers e os utiliza, por exemplo, para gerar as URLs corretas em redirecionamentos.

/// info | Informação

`users.router` contém o `APIRouter` dentro do arquivo `app/routers/users.py`.

E `items.router` contém o `APIRouter` dentro do arquivo `app/routers/items.py`.

///

Com `app.include_router()` podemos adicionar cada `APIRouter` ao aplicativo principal `FastAPI`.
