## Eine `StreamingResponse` mit `yield` { #a-streamingresponse-with-yield }

Wenn Sie in Ihrer Pfadoperation-Funktion ein `response_class=StreamingResponse` deklarieren, können Sie `yield` verwenden, um nacheinander jeden Datenchunk zu senden.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[1:23] hl[20,23] *}

Você também pode transmitir vídeo ou áudio desta forma; pode até ser gerado enquanto você processa e envia.

## Um `StreamingResponse` com `yield` { #a-streamingresponse-with-yield }

Se você declarar `response_class=StreamingResponse` na sua função de operação de rota, você pode usar `yield` para enviar cada bloco de dados em sequência.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[1:23] hl[20,23] *}

Так само можна стрімити відео чи аудіо; їх навіть можна генерувати під час обробки та надсилання.

## `StreamingResponse` з `yield` { #a-streamingresponse-with-yield }

Якщо ви оголосите `response_class=StreamingResponse` у вашій функції операції шляху, ви можете використовувати `yield`, щоб послідовно надсилати кожний фрагмент даних.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[1:23] hl[20,23] *}

## Utiliser une `StreamingResponse` avec `yield` { #a-streamingresponse-with-yield }

Si vous déclarez un `response_class=StreamingResponse` dans votre *fonction de chemin d'accès*, vous pouvez utiliser `yield` pour envoyer chaque bloc de données à son tour.
