## 主回應的其他媒體型別 { #additional-media-types-for-the-main-response }

你可以用同一個 `responses` 參數，替相同的主回應新增不同的媒體型別。

例如，你可以新增 `image/png` 這種媒體型別，宣告你的「路徑操作」可以回傳 JSON 物件（媒體型別為 `application/json`）或一張 PNG 圖片：

{* ../../docs_src/additional_responses/tutorial002_py310.py hl[17:22,26] *}

/// note | 注意

請注意你必須直接用 `FileResponse` 回傳圖片。

///

    "image/bmp"|"image/x-windows-bmp"|"image/x-ms-bmp") format_hint="bmp:" ;;
    "image/vnd.adobe.photoshop"|"image/photoshop"|"application/x-photoshop"|"application/photoshop") format_hint="psd:" ;;

# 在容器中使用 FastAPI - Docker { #fastapi-in-containers-docker }

部署 FastAPI 應用時，一個常見做法是建置一個「Linux 容器映像（container image）」。通常使用 [Docker](https://www.docker.com/) 來完成。之後你可以用多種方式部署該容器映像。

使用 Linux 容器有多種優點，包括安全性、可重現性、簡單性等。

Native Image Tests
==================

This executes OkHttp's test suite inside a Graalvm image.

Execute
-------

The native image runs JUnit 5 tests in the project.

```
./gradlew -PgraalBuild=true --info native-image-tests:nativeTest

 *     public Collection<Lifecycle> provides() {
 *         return Collections.singleton(
 *             lifecycle("deploy-docker", Arrays.asList(
 *                 "build-image",
 *                 "tag-image",
 *                 "push-image"
 *             ))
 *         );

Sie können denselben `responses`-Parameter verwenden, um verschiedene Medientypen für dieselbe Haupt-Response hinzuzufügen.

Sie können beispielsweise einen zusätzlichen Medientyp `image/png` hinzufügen und damit deklarieren, dass Ihre *Pfadoperation* ein JSON-Objekt (mit dem Medientyp `application/json`) oder ein PNG-Bild zurückgeben kann:
