启动和关闭的逻辑很可能是连接在一起的，你可能希望启动某个东西然后结束它，获取一个资源然后释放它等等。

在不共享逻辑或变量的不同函数中处理这些逻辑比较困难，因为你需要在全局变量中存储值或使用类似的方式。

因此，推荐使用 `lifespan` 。

## 技术细节

只是为好奇者提供的技术细节。🤓

在底层，这部分是<a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">生命周期协议</a>的一部分，参见 ASGI 技术规范，定义了称为启动（`startup`）和关闭（`shutdown`）的事件。
