## 使用 FastAPI 流式传输 JSON Lines { #stream-json-lines-with-fastapi }

要在 FastAPI 中流式传输 JSON Lines，可以在路径操作函数中不用 `return`，而是用 `yield` 逐个产生每个数据项。

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

如果你要返回的每个 JSON 项是类型 `Item`（一个 Pydantic 模型），并且这是一个异步函数，你可以将返回类型声明为 `AsyncIterable[Item]`：
