asynchrone Funktionsaufrufe in Ihre Tests integrieren (z. B. bei Verwendung von [MongoDBs MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)), dann denken Sie daran, Objekte zu instanziieren, die einen Event Loop nur innerhalb asynchroner Funktionen benötigen, z. B. einen `@app.on_event("startup")`-Callback.

事件函数既可以声明为异步函数（`async def`），也可以声明为普通函数（`def`）。

### `startup` 事件 { #startup-event }

使用事件 `"startup"` 声明一个在应用启动前运行的函数：

{* ../../docs_src/events/tutorial001_py310.py hl[8] *}

本例中，`startup` 事件处理器函数为项目“数据库”（只是一个 `dict`）提供了一些初始值。

**FastAPI** 支持多个事件处理器函数。

只有所有 `startup` 事件处理器运行完毕，**FastAPI** 应用才开始接收请求。

### `shutdown` 事件 { #shutdown-event }

使用事件 `"shutdown"` 声明一个在应用关闭时运行的函数：
