If a certificate is presented for authentication and has its signing CA key is in this file, then it may be
used for authentication for any user listed in the certificate's principals list. 

Note that certificates that lack a list of principals will not be permitted for authentication using trusted-user-ca-key.

Cela diffère de l'utilisation d'un `APIRouter`, car une application montée est complètement indépendante. L'OpenAPI et les documents de votre application principale n'incluront rien provenant de l'application montée, etc.

Vou mostrar alguns dos principais conceitos que você provavelmente deve ter em mente ao implantar uma aplicação **FastAPI** (embora a maior parte se aplique a qualquer outro tipo de aplicação web).
