 * worse performance than data access by row key.

Wenn Sie die Abhängigkeit `common_parameters()` verwenden, müssen Sie den gesamten Parameter mit der Typannotation und `Depends()` schreiben:

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

Da wir jedoch `Annotated` verwenden, können wir diesen `Annotated`-Wert in einer Variablen speichern und an mehreren Stellen verwenden:

For example:

* **Audio** or **image processing**.
* **Computer vision**: an image is composed of millions of pixels, each pixel has 3 values / colors, processing that normally requires computing something on those pixels, all at the same time.

## 共用 `Annotated` 依賴 { #share-annotated-dependencies }

在上面的範例中，可以看到有一點點的「重複程式碼」。

當你要使用 `common_parameters()` 這個依賴時，你得寫出完整的型別註解搭配 `Depends()`：

```Python
commons: Annotated[dict, Depends(common_parameters)]
```

但因為我們在使用 `Annotated`，我們可以把這個 `Annotated` 的值存到一個變數中，並在多個地方重複使用：

{* ../../docs_src/dependencies/tutorial001_02_an_py310.py hl[12,16,21] *}

/// tip | 提示

* Imposer la sécurité, l’authentification, des exigences de rôles, etc.
* Et bien d’autres choses ...

Tout cela, en minimisant la répétition de code.

## Premiers pas { #first-steps }

Voyons un exemple très simple. Il sera tellement simple qu’il n’est pas très utile, pour l’instant.

Mais de cette façon nous pouvons nous concentrer sur le fonctionnement du système d’**injection de dépendances**.

```console

<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure

Result (German):
