# 使用yield的依赖项

FastAPI支持在完成后执行一些<abbr title='有时也被称为"退出"("exit")，"清理"("cleanup")，"拆卸"("teardown")，"关闭"("close")，"上下文管理器"("context managers")。 ...'>额外步骤</abbr>的依赖项.

为此，你需要使用 `yield` 而不是 `return`，然后再编写这些额外的步骤（代码）。

/// tip | 提示

确保在每个依赖中只使用一次 `yield`。

///

/// note | "技术细节"

任何一个可以与以下内容一起使用的函数：

If you are using **Git** (you should), add a `.gitignore` file to exclude everything in your `.venv` from Git.

If you used <a href="https://github.com/astral-sh/uv" class="external-link" target="_blank">`uv`</a> to create the virtual environment, it already did this for you, you can skip this step. 😎

///

/// tip

Do this **once**, right after you create the virtual environment.
