## Dependências para um grupo de *operações de rota*

Mais a frente, quando você ler sobre como estruturar aplicações maiores ([Bigger Applications - Multiple Files](../../tutorial/bigger-applications.md){.internal-link target=_blank}), possivelmente com múltiplos arquivos, você aprenderá a declarar um único parâmetro `dependencies` para um grupo de *operações de rota*.

## Dependências globais

## Exemplo

Para um exemplos simples, vamos considerar uma estrutura de arquivos semelhante ao descrito em [Bigger Applications](../tutorial/bigger-applications.md){.internal-link target=_blank} e [Testing](../tutorial/testing.md){.internal-link target=_blank}:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

    prefix="/admin",
    tags=["admin"],
    dependencies=[Depends(get_token_header)],
    responses={418: {"description": "I'm a teapot"}},
)


@app.get("/")
async def root():

     * credentials try try when accessing SMB resources described by the <tt>getRequestingURL</tt> and
     * <tt>getRequestingException</tt> methods.
     * If this method returns <tt>null</tt> the <tt>SmbAuthException</tt> that triggered the authenticator check will
     * simply be rethrown. The default implementation returns <tt>null</tt>.
     */
    protected NtlmPasswordAuthenticator getNtlmPasswordAuthentication () {
        return null;
    }

つまり、すでにどこかで使っている通常の依存関係（値を返すもの）を再利用することができ、値は使われなくても依存関係は実行されます:

```Python hl_lines="9 14"
{!../../docs_src/dependencies/tutorial006.py!}
```
