### Úsalo

Ahora puedes pasar ese `oauth2_scheme` en una dependencia con `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

Esta dependencia proporcionará un `str` que se asigna al parámetro `token` de la *path operation function*.

**FastAPI** sabrá que puede usar esta dependencia para definir un "security scheme" en el esquema OpenAPI (y en los docs automáticos del API).

        assertFalse(emptyIterator.hasNext(), "Empty iterator should have no next element");

        // Note: Standard Iterator would throw NoSuchElementException, but this implementation returns null
        // This is a design choice for this specific implementation
        assertNull(emptyIterator.next(), "This implementation returns null instead of throwing");

        // Verify remove can be called (even though no-op)

        return redirect(getClass());
    }

The special key `default` indicates a Go version to take unspecified
settings from. This allows setting the GODEBUG defaults separately
from the Go language version in the module.
In this example, the program is asking for Go 1.21 semantics and
then asking for the old pre-Go 1.21 `panic(nil)` behavior and the
new Go 1.23 `asynctimerchan=0` behavior.

Only the work module's `go.mod` is consulted for `godebug` directives.
