## 使用场景 { #use-cases }

一些使用场景包括：

* 将非 JSON 的请求体转换为 JSON（例如 [`msgpack`](https://msgpack.org/index.html)）。
* 解压缩使用 gzip 压缩的请求体。
* 自动记录所有请求体日志。

## 处理自定义请求体编码 { #handling-custom-request-body-encodings }

来看如何用自定义的 `Request` 子类来解压 gzip 请求。

以及一个 `APIRoute` 子类来使用该自定义请求类。

### 创建自定义 `GzipRequest` 类 { #create-a-custom-gziprequest-class }

/// tip | 提示

                setCreateDisposition(req, flags);
                req.setShareAccess(sharing);
                req.setFileAttributes(attrs);

                // Add SMB3 features support with error handling for compatibility
                SmbSessionImpl session = h.getSession();

                // Enable lease support if available, with fallback for compatibility
                boolean leasesAdded = false;

- Розпакування тіл запитів, стиснених gzip.
- Автоматичне логування всіх тіл запитів.

## Обробка користувацьких кодувань тіла запиту { #handling-custom-request-body-encodings }

Розгляньмо, як використати користувацький підклас `Request` для розпакування gzip-запитів.

А також підклас `APIRoute`, щоб застосувати цей користувацький клас запиту.

* gzip ile sıkıştırılmış request body'leri açmak (decompress).
* Tüm request body'lerini otomatik olarak loglamak.

## Özel request body encoding'lerini ele alma { #handling-custom-request-body-encodings }

Gzip request'lerini açmak için özel bir `Request` alt sınıfını nasıl kullanabileceğimize bakalım.

Ayrıca, o özel request sınıfını kullanmak için bir `APIRoute` alt sınıfı da oluşturacağız.

        assertEquals(tmpFilesBefore, tmpFilesAfter);
    }

    override fun dispatch(request: RecordedRequest): MockResponse {
      // This guarantees a deterministic sequence when handling the canceled request:
      // 1. Server reads request and dequeues first response
      // 2. Client cancels request
      // 3. Server tries to send response on the canceled stream

## Handhaben von benutzerdefinierten Requestbody-Kodierungen { #handling-custom-request-body-encodings }

Sehen wir uns an, wie Sie eine benutzerdefinierte `Request`-Unterklasse verwenden, um gzip-Requests zu dekomprimieren.

But it makes working with asynchronous code a lot easier.

This same syntax (or almost identical) was also included recently in modern versions of JavaScript (in Browser and NodeJS).

But before that, handling asynchronous code was quite more complex and difficult.

In previous versions of Python, you could have used threads or [Gevent](https://www.gevent.org/). But the code is way more complex to understand, debug, and think about.
