## Ajouter des expressions régulières { #add-regular-expressions }

Vous pouvez définir un `pattern` d’<dfn title="Une expression régulière, regex ou regexp, est une suite de caractères qui définit un motif de recherche pour les chaînes de caractères.">expression régulière</dfn> auquel le paramètre doit correspondre :

* Объявление **параметров** из других источников: **HTTP-заголовки**, **cookies**, **поля формы** и **файлы**.
* Как задать **ограничения валидации** вроде `maximum_length` или `regex`.
* Очень мощную и простую в использовании систему **<dfn title="также известна как: компоненты, ресурсы, провайдеры, сервисы, инъекции">внедрения зависимостей</dfn>**.

**Spoiler alert**: öğretici - kullanıcı rehberi şunları içerir:

* **parameter**'ların farklı yerlerden: **header**'lar, **cookie**'ler, **form alanları** ve **file**'lar olarak tanımlanması.
* `maximum_length` ya da `regex` gibi **doğrulama kısıtlamalarının** nasıl ayarlanacağı.
* Çok güçlü ve kullanımı kolay bir **<dfn title="şöyle de bilinir: bileşenler, kaynaklar, sağlayıcılar, servisler, enjekte edilebilirler">Bağımlılık Enjeksiyonu</dfn>** sistemi.
