...bu çalışır:

Ve elbette, bazı parametreleri zorunlu, bazılarını varsayılan değerli, bazılarını da tamamen isteğe bağlı olarak tanımlayabilirsiniz:

Bu durumda, 3 tane query parametresi vardır:

Birçok durumda, FastAPI uygulamanızın önünde Traefik veya Nginx gibi bir **proxy** kullanırsınız.

Bu proxy'ler HTTPS sertifikalarını ve diğer bazı işleri üstlenebilir.
