而当使用默认的 `Depends(scope="request")` 时，`yield` 之后的退出代码会在响应发送之后执行。

你可以在文档 [带 `yield` 的依赖项 - 提前退出与 `scope`](../tutorial/dependencies/dependencies-with-yield.md#early-exit-and-scope) 中了解更多。

### 带 `yield` 的依赖项与 `StreamingResponse`（技术细节） { #dependencies-with-yield-and-streamingresponse-technical-details }

在 FastAPI 0.118.0 之前，如果你使用带 `yield` 的依赖项，它会在*路径操作函数*返回后、发送响应之前运行 `yield` 之后的退出代码。
