{!../../../docs_src/events/tutorial003.py!} ``` Ein **Kontextmanager** in Python ist etwas, das Sie in einer `with`-Anweisung verwenden können, zum Beispiel kann `open()` als Kontextmanager verwendet werden: ```Python with open("file.txt") as file: file.read() ``` In neueren Versionen von Python gibt es auch einen **asynchronen Kontextmanager**. Sie würden ihn mit `async with` verwenden: ```Python async with lifespan(app): await do_stuff()

{!../../../docs_src/events/tutorial003.py!} ``` Um **gerenciador de contexto** em Python é algo que você pode usar em uma declaração `with`, por exemplo, `open()` pode ser usado como um gerenciador de contexto: ```Python with open("file.txt") as file: file.read() ``` Nas versões mais recentes de Python, há também um **gerenciador de contexto assíncrono**. Você o usaria com `async with`: ```Python async with lifespan(app): await do_stuff()

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 使用 `shutdown` 事件声明 `app` 关闭时运行的函数: ```Python hl_lines="6" {!../../../docs_src/events/tutorial002.py!} ``` 此处,`shutdown` 事件处理器函数在 `log.txt` 中写入一行文本 `Application shutdown`。 !!! info "说明" `open()` 函数中,`mode="a"` 指的是**追加**。因此这行文本会添加在文件已有内容之后,不会覆盖之前的内容。 !!! tip "提示" 注意,本例使用 Python `open()` 标准函数与文件交互。 这个函数执行 I/O(输入/输出)操作,需要等待内容写进磁盘。

응용 프로그램이 종료될 때 실행하려는 함수를 추가하려면 `"shutdown"` 이벤트로 선언합니다: ```Python hl_lines="6" {!../../../docs_src/events/tutorial002.py!} ``` 이 예제에서 `shutdown` 이벤트 핸들러 함수는 `"Application shutdown"`이라는 텍스트가 적힌 `log.txt` 파일을 추가할 것입니다. !!! info "정보" `open()` 함수에서 `mode="a"`는 "추가"를 의미합니다. 따라서 이미 존재하는 파일의 내용을 덮어쓰지 않고 새로운 줄을 추가합니다. !!! tip "팁" 이 예제에서는 파일과 상호작용 하기 위해 파이썬 표준 함수인 `open()`을 사용하고 있습니다.
