minio/minio ``` ### Installing certificates from third party CAs MinIO can connect to other servers, including MinIO nodes or other server types such as NATs and Redis. If these servers use certificates that were not registered with a known CA, add trust for these certificates to MinIO Server by bundling these certificates into a Kubernetes secret and providing it to Helm via the `trustedCertsSecret` value. If `.Values.tls.enabled` is `true` and you're installing certificates for third party CAs, remember...

    * Ceci sera également utilisé par les outils de génération automatique de code client.
* **Sérialiser** les données renvoyées en JSON en utilisant Pydantic, qui est écrit en **Rust**, ce qui sera **beaucoup plus rapide**.

Mais surtout :

* Il **limitera et filtrera** les données de sortie à ce qui est défini dans le type de retour.

如果你追求效能，使用[回應模型](../tutorial/response-model.md) 大概會比使用 `orjson` 回應更好。

有了回應模型，FastAPI 會使用 Pydantic 直接將資料序列化為 JSON，而不需要像其他情況那樣先經過 `jsonable_encoder` 之類的中介步驟。

而且在底層，Pydantic 用來序列化為 JSON 的 Rust 機制和 `orjson` 相同，因此用回應模型已經能獲得最佳效能。

## 預設回應類別 { #default-response-class }

在建立 **FastAPI** 類別實例或 `APIRouter` 時，你可以指定預設要使用哪個回應類別。

用來設定的是 `default_response_class` 參數。

* Then **comment** saying that you did that, that's how I will know you really checked it.

/// info

Unfortunately, I can't simply trust PRs that just have several approvals.

* OpenAPI *경로 처리*의 응답에 **JSON Schema**를 추가합니다.
    * 이는 **자동 문서**에서 사용됩니다.
    * 또한 자동 클라이언트 코드 생성 도구에서도 사용됩니다.
* 반환된 데이터를 Pydantic을 사용해 JSON으로 **직렬화**합니다. Pydantic은 **Rust**로 작성되어 있어 **훨씬 더 빠릅니다**.

하지만 가장 중요한 것은:

* 반환 타입에 정의된 내용으로 출력 데이터를 **제한하고 필터링**합니다.
    * 이는 특히 **보안**에 매우 중요합니다. 아래에서 더 자세히 살펴보겠습니다.
