`images`キーが画像オブジェクトのリストを持つようになったことに注目してください。

///

## 深くネストされたモデル

深くネストされた任意のモデルを定義することができます:

{* ../../docs_src/body_nested_models/tutorial007.py hl[9,14,20,23,27] *}

/// info | 情報

`Offer`は`Item`のリストであり、オプションの`Image`のリストを持っていることに注目してください。

## 純粋なリストのボディ

期待するJSONボディのトップレベルの値がJSON`array`（Pythonの`list`）であれば、Pydanticモデルと同じように、関数のパラメータで型を宣言することができます:

```Python
images: List[Image]

     * on what they know about the particular Joiner instances the calls are performed on.
     *
     * (In addition to useForNull, we also offer skipNulls. It, too, tolerates null inputs, but its
     * tolerance is implemented differently: Its implementation avoids calling this toString(Object)
     * method in the first place.)
     */
    requireNonNull(part);

			x.versions = append(x.versions[:i], x.versions[i+1:]...)
			// if uv has tiered content we add a
			// free-version to track it for
			// asynchronous deletion via scanner.
			if freeVersion, toFree := ver.ObjectV2.InitFreeVersion(fi); toFree {
				err = x.addVersion(freeVersion)
			}
		}

		if fi.Deleted {
			err = x.addVersion(ventry)
		}

Si estás ejecutando tu contenedor detrás de un Proxy de Terminación TLS (load balancer) como Nginx o Traefik, añade la opción `--proxy-headers`, esto le dirá a Uvicorn (a través de la CLI de FastAPI) que confíe en los headers enviados por ese proxy indicando que la aplicación se está ejecutando detrás de HTTPS, etc.

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```

**This release candidate turns on web socket compression.**

The [spec][rfc_7692] includes a sophisticated mechanism for client and server to negotiate
compression features. We strive to offer great performance in our default configuration and so we're
making compression the default for everyone starting with this release candidate.
