different loop` when integrating asynchronous function calls in your tests (e.g. when using [MongoDB's MotorClient](https://stackoverflow.com/questions/41584243/runtimeerror-task-attached-to-a-different-loop)), remember to instantiate objects that need an event loop only within async functions, e.g. an `@app.on_event("startup")` callback.

In addition to individual updates that happen on demand, all dependencies in
the std and cmd modules are updated to their latest available versions at least
twice during every major release cycle. This is done to avoid the possibility of
some dependencies being left on very old versions and in turn make their eventual
update more disruptive. This recurring process is tracked in go.dev/issue/36905.

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：

		prev.Count++
		l.IDMap[id] = prev
		shouldLog = false
	}
	l.Unlock()

	if shouldLog {
		logIf(ctx, subsystem, err, errKind...)
	}
}

// Cleanup the map every one hour so that the log message is printed again for the user to notice.
func (l *logOnceType) cleanupRoutine() {
	for {
		time.Sleep(time.Hour)

		l.Lock()
		l.IDMap = make(map[string]onceErr)
		l.Unlock()

        }
        List<LogNotificationEvent> events = helper.drainAll();
        // The newest events should be retained; oldest dropped
        // Last event should be msg1099
        LogNotificationEvent last = events.get(events.size() - 1);
        assertEquals("msg1099", last.getMessage());
    }
