## Utilizando a dependência { #use-the-dependency }

Então podemos utilizar a dependência com:

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

/// info | Informação

Perceba que nós estamos declarando apenas uma dependência na *função de operação de rota*, em `query_or_cookie_extractor`.

 *
 * Supported on Android 2.3+.
 * Supported on JDK 8+ via Conscrypt.
 *
 * ### ALPN (Application Layer Protocol Negotiation)
 *
 * Supported on Android 5.0+.
 *
 * Supported on OpenJDK 8 via the JettyALPN-boot library or Conscrypt.
 *
 * Supported on OpenJDK 9+ via SSLParameters and SSLSocket features.
 *
 * ### Trust Manager Extraction

## Die Abhängigkeit verwenden { #use-the-dependency }

Diese Abhängigkeit verwenden wir nun wie folgt:

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

/// info | Info

Beachten Sie, dass wir in der *Pfadoperation-Funktion* nur eine einzige Abhängigkeit deklarieren, den `query_or_cookie_extractor`.

Затем вы можете использовать этот новый класс в `response_class=PNGStreamingResponse` в своей *функции-обработчике пути*:

{* ../../docs_src/stream_data/tutorial002_py310.py ln[23:27] hl[23] *}

### Симулировать файл { #simulate-a-file }

В этом примере мы симулируем файл с помощью `io.BytesIO` — это «файлоподобный» объект, который существует только в памяти, но позволяет использовать тот же интерфейс.

## Usa la dependencia { #use-the-dependency }

Entonces podemos usar la dependencia con:

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

/// info | Información

Fíjate que solo estamos declarando una dependencia en la *path operation function*, `query_or_cookie_extractor`.
