 * The last point is subtle. Often the observable object will be managing its own internal state

## O que é "Injeção de Dependência"

**"Injeção de Dependência"** no mundo da programação significa, que existe uma maneira de declarar no seu código (nesse caso, suas *funções de operação de rota*) para declarar as coisas que ele precisa para funcionar e que serão utilizadas: "dependências".

Então, esse sistema (nesse caso o **FastAPI**) se encarrega de fazer o que for preciso para fornecer essas dependências para o código ("injetando" as dependências).

A "bearer" token is not the only option.

But it's the best one for our use case.

And it might be the best for most use cases, unless you are an OAuth2 expert and know exactly why there's another option that better suits your needs.

In that case, **FastAPI** also provides you with the tools to build it.
