Im vorherigen Kapitel hat das Sicherheitssystem (das auf dem Dependency Injection System basiert) der *Pfadoperation-Funktion* einen `token` vom Typ `str` überreicht:

{* ../../docs_src/security/tutorial001_an_py310.py hl[12] *}

Aber das ist immer noch nicht so nützlich.

Lassen wir es uns den aktuellen Benutzer überreichen.
