但由于 `generate_stream()` 并不使用数据库会话，因此在发送响应期间保持会话打开并非必要。

如果你使用的是 SQLModel（或 SQLAlchemy）并碰到这种特定用例，你可以在不再需要时显式关闭会话：

{* ../../docs_src/dependencies/tutorial014_an_py310.py ln[24:28] hl[28] *}

这样会话会释放数据库连接，让其他请求可以使用。

如果你还有其他需要在 `yield` 依赖项中提前退出的用例，请创建一个 [GitHub 讨论问题](https://github.com/fastapi/fastapi/discussions/new?category=questions)，说明你的具体用例以及为何提前关闭会对你有帮助。

如果确有有力的用例需要提前关闭，我会考虑新增一种选择性启用提前关闭的方式。

但因為 `generate_stream()` 並未使用資料庫 session，實際上不需要在傳送回應時保持 session 開啟。

如果你用的是 SQLModel（或 SQLAlchemy）且有這種特定情境，你可以在不再需要時明確關閉該 session：

{* ../../docs_src/dependencies/tutorial014_an_py310.py ln[24:28] hl[28] *}

如此一來，該 session 就會釋放資料庫連線，讓其他請求可以使用。

如果你有不同的情境，需要從含有 `yield` 的相依中提早結束，請建立一個 [GitHub 討論問題](https://github.com/fastapi/fastapi/discussions/new?category=questions)，描述你的具體情境，以及為何提早關閉含有 `yield` 的相依對你有幫助。
