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.

Then APIStar stopped to exist as a server and Starlette was created, and was a new better foundation for such a system. That was the final inspiration to build **FastAPI**.

I consider **FastAPI** a "spiritual successor" to APIStar, while improving and increasing the features, typing system, and other parts, based on the learnings from all these previous tools.
