Then we can use the dependency with:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

/// info

Notice that we are only declaring one dependency in the *path operation function*, the `query_or_cookie_extractor`.

But **FastAPI** will know that it has to solve `query_extractor` first, to pass the results of that to `query_or_cookie_extractor` while calling it.

///

```mermaid

Logo, a seção com:

{% raw %}

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

{% endraw %}

...irá gerar um link para a mesma URL que será tratada pela *path operation function* `read_item(id=id)`.

Por exemplo, com um ID de `42`, isso renderizará:

```html

Para alguns tipos de aplicação específicos você pode querer adicionar dependências para toda a aplicação.

De forma semelhante a [adicionar dependências (`dependencies`) em *decoradores de operação de rota*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, você pode adicioná-las à aplicação `FastAPI`.

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:

        handler -->> client: HTTP-Error-Response
    end
    operation ->> client: Sendet Response an Client
    Note over client,operation: Response wurde gesendet, kann nicht mehr geändert werden
    opt Tasks
        operation -->> tasks: Sendet Hintergrundtasks
    end
    opt Löst andere Exception aus
        tasks -->> tasks: Handhabt Exception im Hintergrundtask-Code
    end
```

/// info

// If the most recent read or write operation on the buffer was
// not a successful [Buffer.ReadRune], UnreadRune returns an error.  (In this regard
// it is stricter than [Buffer.UnreadByte], which will unread the last byte
// from any read operation.)
func (b *Buffer) UnreadRune() error {
	if b.lastRead <= opInvalid {
		return errors.New("bytes.Buffer: UnreadRune: previous operation was not a successful ReadRune")
	}

# Globale Abhängigkeiten

Bei einigen Anwendungstypen möchten Sie möglicherweise Abhängigkeiten zur gesamten Anwendung hinzufügen.

Ähnlich wie Sie [`dependencies` zu den *Pfadoperation-Dekoratoren* hinzufügen](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} können, können Sie sie auch zur `FastAPI`-Anwendung hinzufügen.

In diesem Fall werden sie auf alle *Pfadoperationen* in der Anwendung angewendet:
