Aber selbst wenn Sie **FastAPI** nie verwenden, wird es für Sie nützlich sein, ein wenig darüber zu lernen.

Fangen wir mit einem einfachen Beispiel an:

Un token "bearer" no es la única opción.

Pero es la mejor para nuestro caso de uso.

Y podría ser la mejor para la mayoría de los casos de uso, a menos que seas un experto en OAuth2 y sepas exactamente por qué hay otra opción que se adapta mejor a tus necesidades.

En ese caso, **FastAPI** también te proporciona las herramientas para construirlo.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

And it can return anything you want.

In this case, this dependency expects:

* An optional query parameter `q` that is a `str`.
* An optional query parameter `skip` that is an `int`, and by default is `0`.
* An optional query parameter `limit` that is an `int`, and by default is `100`.
