    !!! tip "Подсказка"
        Рекомендуется использовать 'Annotated' версию, если это возможно.

Теперь мы можем изменить зависимость `common_parameters`, указанную выше, на класс `CommonQueryParams`:

首先，创建 `GzipRequest` 类，覆盖解压请求头中请求体的 `Request.body()` 方法。

请求头中没有 `gzip` 时，`GzipRequest` 不会解压请求体。

这样就可以让同一个路由类处理 gzip 压缩的请求或未压缩的请求。

```Python hl_lines="8-15"
{!../../../docs_src/custom_request_and_route/tutorial001.py!}
```

### 创建自定义 `GzipRoute` 类

接下来，创建使用 `GzipRequest` 的 `fastapi.routing.APIRoute  ` 的自定义子类。

此时，这个自定义子类会覆盖 `APIRoute.get_route_handler()`。

경로 매개변수와 요청 본문을 동시에 선언할 수 있습니다.

**FastAPI**는 경로 매개변수와 일치하는 함수 매개변수가 **경로에서 가져와야 한다**는 것을 인지하며, Pydantic 모델로 선언된 그 함수 매개변수는 **요청 본문에서 가져와야 한다**는 것을 인지할 것입니다.

现在试着发送一个无效的 `item`，例如：

```JSON
{
  "title": "towel",
  "size": "XL"
}

```

收到的响应包含 `body` 信息，并说明数据是无效的：

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }
  ],
  "body": {
