Les mêmes modèles sont partagés entre les requêtes, ce n'est donc pas un modèle par requête, ni un par utilisateur, ou quelque chose de similaire.

Imaginons que le chargement du modèle puisse **prendre pas mal de temps**, car il doit lire beaucoup de **données depuis le disque**. Vous ne voulez donc pas le faire pour chaque requête.

Vous pouvez donc utiliser `user_agent` comme vous le feriez normalement dans du code Python, au lieu d'avoir à mettre des majuscules aux premières lettres comme `User_Agent` ou quelque chose de similaire.

Si, pour une raison quelconque, vous devez désactiver la conversion automatique des traits bas en traits d'union, définissez le paramètre `convert_underscores` de `Header` sur `False` :

Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).

Each file is a list of API features, one per line.

go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.

except.txt lists features that may disappear without breaking true
compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"

`Cookie`, `Path` ve `Query`'nin "kardeş" sınıfıdır. O da aynı ortak `Param` sınıfından miras alır.

Ancak `fastapi`'dan `Query`, `Path`, `Cookie` ve diğerlerini import ettiğinizde, bunlar aslında özel sınıflar döndüren fonksiyonlardır, bunu unutmayın.

Cookie'leri tanımlamak için `Cookie` kullanmanız gerekir, aksi halde parametreler query parametreleri olarak yorumlanır.
