Change Log
==========

## Version 4.x

See [4.x Change log](https://square.github.io/okhttp/changelogs/changelog_4x/) for the stable version changelogs.

## Version 5.0.0-alpha.14

_2024-04-17_

 *  Breaking: Move coroutines extensions to okhttp3.coroutines. Previously this artifact shared the
    `okhttp3` package name with our core module, which is incompatible with the Java Platform Module
    System.

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。
