/// note | Detalles técnicos

En la especificación de OpenAPI se llama el [Objeto de Operación](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object).

///

Tiene toda la información sobre la *path operation* y se usa para generar la documentación automática.

Vous pouvez avoir un proxy qui ajoute un préfixe de chemin à votre application.

Dans ces cas, vous pouvez utiliser `root_path` pour configurer votre application.

Le `root_path` est un mécanisme fourni par la spécification ASGI (sur laquelle FastAPI est construit, via Starlette).

Le `root_path` est utilisé pour gérer ces cas spécifiques.

Et il est également utilisé en interne lors du montage de sous‑applications.

* *path*, bir [OpenAPI 3 expression](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression) (aşağıda daha fazlası) içerebilir; böylece parametreler ve sizin API'nize gönderilen orijinal request'in bazı parçalarıyla değişkenler kullanılabilir.

/// note | Teknik Detaylar

OpenAPI spesifikasyonunda buna [Operation Nesnesi](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object) denir.

Bu, *path operation* hakkında tüm bilgileri içerir ve otomatik dokümantasyonu üretmek için kullanılır.
