/// tip | İpucu

[Response Model](../tutorial/response-model.md) kullanmak, doğrudan `JSONResponse` döndürmeye kıyasla genellikle çok daha iyi performans sağlar; çünkü veriyi Pydantic ile, Rust tarafında serialize eder.

///

## Bir `Response` Döndürme { #return-a-response }

Aslında herhangi bir `Response` veya onun herhangi bir alt sınıfını döndürebilirsiniz.

/// info | Bilgi

Normalerweise erzielen Sie eine deutlich bessere Leistung, wenn Sie ein [Responsemodell](../tutorial/response-model.md) verwenden, als wenn Sie direkt eine `JSONResponse` zurückgeben, da die Serialisierung der Daten dabei mit Pydantic in Rust erfolgt.

///

## Eine `Response` zurückgeben { #return-a-response }

Tatsächlich können Sie jede `Response` oder jede Unterklasse davon zurückgeben.

/// info | Info

/// tip | Consejo

Normalmente tendrás mucho mejor rendimiento usando un [Response Model](../tutorial/response-model.md) que devolviendo un `JSONResponse` directamente, ya que de esa forma serializa los datos usando Pydantic, en Rust.

///

## Devolver una `Response` { #return-a-response }

De hecho, puedes devolver cualquier `Response` o cualquier subclase de ella.

/// info | Información

然后，**FastAPI** 会在后台将这些兼容 JSON 的数据（比如字典）放到一个 `JSONResponse` 中，该 `JSONResponse` 会用来发送响应给客户端。

但是你可以在你的 *路径操作* 中直接返回一个 `JSONResponse`。

/// tip | 提示

通常使用 [响应模型](../tutorial/response-model.md) 会比直接返回 `JSONResponse` 拥有更好的性能，因为它会在 Rust 中使用 Pydantic 序列化数据。

///

## 返回 `Response` { #return-a-response }

事实上，你可以返回任意 `Response` 或者任意 `Response` 的子类。

/// info | 信息

`JSONResponse` 本身是一个 `Response` 的子类。

///

Vous aurez normalement une bien meilleure performance en utilisant un [Modèle de réponse](../tutorial/response-model.md) qu'en renvoyant directement une `JSONResponse`, car de cette façon la sérialisation des données est effectuée par Pydantic, en Rust.

///

## Renvoyer une `Response` { #return-a-response }

Vous pouvez renvoyer une `Response` ou n'importe laquelle de ses sous-classes.

    had a crash `IllegalArgumentException: Not a Conscrypt trust manager` because we depended on
    initialization order of companion objects.


## Version 4.7.1

 *  Fix: Pass the right arguments in the trust manager created for `addInsecureHost()`. Without the
    fix insecure hosts crash with an `IllegalArgumentException` on Android.
