さらに、`status_code` パラメータを `response_class` パラメータと組み合わせて使うこともできます:

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

### `StreamingResponse` { #streamingresponse }

非同期ジェネレータ、または通常のジェネレータ/イテレータ（`yield` を持つ関数）を受け取り、レスポンスボディをストリームします。

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

Você também pode utilizar o parâmetro `status_code` combinado com o parâmetro `response_class`:

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

### `StreamingResponse` { #streamingresponse }

Recebe um gerador assíncrono ou um gerador/iterador comum (uma função com `yield`) e transmite (stream) o corpo da resposta.

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

This change also meant that if you returned a `StreamingResponse`, the exit code of the dependency with `yield` would have been already run.

For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not be able to use that session while streaming data because the session would have already been closed in the exit code after `yield`.
