# Signing key for Gradle artifacts

Below is the public PGP key used to sign all Gradle artifacts.

The key ID is `E2F38302C8075E3D` and its fingerprint is `1BD97A6A154E7810EE0BC832E2F38302C8075E3D`.
You can also find the key in the [Gradle website](https://gradle.org/keys/) and on [public key servers](https://keys.openpgp.org/search?q=maven-publishing%40gradle.com).

## Verification instructions

### Importing the key

# Événements de cycle de vie { #lifespan-events }

Vous pouvez définir une logique (du code) qui doit être exécutée avant que l'application ne **démarre**. Cela signifie que ce code sera exécuté **une seule fois**, **avant** que l'application ne **commence à recevoir des requêtes**.

Örneğin, varsayılan `401 Unauthorized` hatası yerine `403 Forbidden` hatası döndüren bir `HTTPBearer` alt sınıfı oluşturabilirsiniz:

Aslında, `Query`, `Path` ve birazdan göreceğiniz diğerleri, ortak bir `Param` sınıfının alt sınıflarından nesneler oluşturur; `Param` sınıfı da Pydantic'in `FieldInfo` sınıfının bir alt sınıfıdır.

Pydantic'in `Field`'ı da `FieldInfo`'nun bir instance'ını döndürür.
