/// tip | Dica

Você pode definir uma sobreposição de dependência para uma dependência que é utilizada em qualquer lugar da sua aplicação **FastAPI**.

A dependência original pode estar sendo utilizada em uma *função de operação de rota*, um *docorador de operação de rota* (quando você não utiliza o valor retornado), uma chamada ao `.include_router()`, etc.

O FastAPI ainda poderá sobrescrevê-lo.

///

Para isso você precisa acessar a requisição diretamente.

{* ../../docs_src/using_request_directly/tutorial001.py hl[1,7:8] *}

Ao declarar o parâmetro com o tipo sendo um `Request` em sua *função de operação de rota*, o **FastAPI** saberá como passar o `Request` neste parâmetro.

/// tip | Dica

Note que neste caso, nós estamos declarando o parâmetro da rota ao lado do parâmetro da requisição.
