/// tip | Dica

Leve em condideração que o JSON só suporta `str` como chaves.

Mas o Pydantic tem conversão automática de dados.

Isso significa que, embora os clientes da API só possam enviar strings como chaves, desde que essas strings contenham inteiros puros, o Pydantic irá convertê-los e validá-los.

E o `dict` que você recebe como `weights` terá, na verdade, chaves `int` e valores` float`.

Aquí tienes una representación visual de cómo el **proxy** añade headers reenviados entre el cliente y el **application server**:

    participant Client as Cliente
    participant Proxy as Proxy/Load Balancer
    participant Server as Servidor de FastAPI

    Client->>Proxy: HTTPS Request<br/>Host: mysuperapp.com<br/>Path: /items

    Note over Proxy: El proxy añade headers reenviados

But there are specific cases where it's useful to get the `Request` object.

## Use the `Request` object directly { #use-the-request-object-directly }

Let's imagine you want to get the client's IP address/host inside of your *path operation function*.

For that you need to access the request directly.
