`Depends`'e yalnızca tek bir parametre verirsiniz.

Bu parametre, bir fonksiyon gibi bir şey olmalıdır.

Onu doğrudan **çağırmazsınız** (sonuna parantez eklemezsiniz), sadece `Depends()`'e parametre olarak verirsiniz.

Ve bu fonksiyon da, *path operation function*'lar gibi parametre alır.

# Cookie 參數模型 { #cookie-parameter-models }

如果你有一組彼此相關的「**Cookie**」，你可以建立一個「**Pydantic 模型**」來宣告它們。🍪

這樣你就能在**多處**重複使用該模型，並且能一次性為所有參數宣告**驗證**與**中繼資料**。😎

/// note | 注意

自 FastAPI 版本 `0.115.0` 起支援。🤓

///

/// tip

同樣的技巧也適用於 `Query`、`Cookie` 與 `Header`。😎

## 以 Pydantic 模型宣告 Cookie { #cookies-with-a-pydantic-model }

在 **Pydantic 模型**中宣告所需的 **Cookie** 參數，接著將參數宣告為 `Cookie`：

## Mit `Last-Event-ID` fortsetzen { #resuming-with-last-event-id }

Wenn ein Browser nach einem Verbindungsabbruch erneut verbindet, sendet er die zuletzt empfangene `id` im Header `Last-Event-ID`.

Sie können ihn als Header-Parameter einlesen und verwenden, um den Stream dort fortzusetzen, wo der Client aufgehört hat:

{* ../../docs_src/server_sent_events/tutorial004_py310.py hl[25,27,31] *}

### Arguments de `url_for` dans le template { #template-url-for-arguments }

Vous pouvez aussi utiliser `url_for()` dans le template ; elle prend en paramètres les mêmes arguments que ceux utilisés par votre *fonction de chemin d'accès*.

Ainsi, la section suivante :

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}
