     * Automatically accept changes that are valid property upgrades of a getter or setter.

     * Here we automatically accept the following cases:
     * - A setter `setX` of an upgraded property is removed
     * - A boolean `isX` of an upgraded property is removed
     * - A new getter `getX` is added, where the old getter is a boolean getter `isX` of an upgraded property

在某些情況下，你可能想要覆寫 `Request` 與 `APIRoute` 類別所使用的邏輯。

特別是，這可能是替代中介軟體（middleware）中實作邏輯的一個好方法。

例如，如果你想在應用程式處理之前讀取或操作請求本文（request body）。

/// danger

這是進階功能。

如果你剛開始使用 **FastAPI**，可以先跳過本節。

///

## 使用情境 { #use-cases }

可能的使用情境包括：

* 將非 JSON 的請求本文轉換為 JSON（例如 [`msgpack`](https://msgpack.org/index.html)）。
* 解壓縮以 gzip 壓縮的請求本文。
* 自動記錄所有請求本文。

## 處理自訂請求本文編碼 { #handling-custom-request-body-encodings }

/// info | 信息

关键在于你的应用可以逐行生成数据，而客户端在消费前面的行。

///

/// note | 技术细节

由于每个 JSON 对象将以换行分隔，它们的内容中不能包含字面量换行符，但可以包含转义换行符（`\n`），这属于 JSON 标准的一部分。

不过通常你无需操心，这些都会自动完成，继续阅读即可。🤓

///

## 使用场景 { #use-cases }

你可以用它来从 AI LLM 服务、日志或遥测中流式传输数据，或其他可以用 JSON 项目来结构化的数据。

/// tip | 提示

如果你想流式传输二进制数据，例如视频或音频，请查看进阶指南：[流式传输数据](../advanced/stream-data.md)。
