You can also use the `status_code` parameter combined with the `response_class` parameter:

{* ../../docs_src/custom_response/tutorial006c_py310.py hl[2,7,9] *}

### `StreamingResponse` { #streamingresponse }

Takes an async generator or a normal generator/iterator (a function with `yield`) and streams the response body.

{* ../../docs_src/custom_response/tutorial007_py310.py hl[3,16] *}

在此情況下，所使用的 `status_code` 會是 `RedirectResponse` 的預設值 `307`。

你也可以同時搭配 `status_code` 與 `response_class` 參數：

{* ../../docs_src/custom_response/tutorial006c_py310.py hl[2,7,9] *}

### `StreamingResponse` { #streamingresponse }

接收一個 async 產生器或一般的產生器／疊代器（帶有 `yield` 的函式），並以串流方式傳送回應本文。

{* ../../docs_src/custom_response/tutorial007_py310.py hl[3,16] *}

/// note | 技術細節

## Streaming (JSON Lines, SSE, bytes)

See [the streaming reference](references/streaming.md) for JSON Lines, Server-Sent Events (`EventSourceResponse`, `ServerSentEvent`), and byte streaming (`StreamingResponse`) patterns.

## Tooling

See [the other tools reference](references/other-tools.md) for details on uv, Ruff, ty for package management, linting, type checking, formatting, etc.

## Other Libraries

## «`StreamingResponse` с `yield`» { #a-streamingresponse-with-yield }

Если вы укажете `response_class=StreamingResponse` в своей *функции-обработчике пути*, вы можете использовать `yield`, чтобы по очереди отправлять каждый чанк данных.

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

## Un `StreamingResponse` con `yield` { #a-streamingresponse-with-yield }

Si declaras un `response_class=StreamingResponse` en tu *path operation function*, puedes usar `yield` para enviar cada bloque de datos a su vez.

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

FastAPI entregará cada bloque de datos a `StreamingResponse` tal cual, no intentará convertirlo a JSON ni nada parecido.

Vous pouvez aussi diffuser de la **vidéo** ou de l'**audio** de cette manière ; cela peut même être généré au fil du traitement et de l'envoi.

## 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.

## `yield` ile bir `StreamingResponse` { #a-streamingresponse-with-yield }

*Path operation function* içinde `response_class=StreamingResponse` belirtirseniz, her veri parçasını sırayla göndermek için `yield` kullanabilirsiniz.

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

FastAPI her veri parçasını olduğu gibi `StreamingResponse`'a verir; JSON'a ya da benzeri bir formata dönüştürmeye çalışmaz.

Sie könnten auf diese Weise auch **Video** oder **Audio** streamen, es könnte sogar beim Verarbeiten erzeugt und gesendet werden.

## 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] *}
