发生异常时，`Request` 实例仍在作用域内，因此处理错误时可以读取和使用请求体：

```Python hl_lines="16-18"

```

## 在路由中自定义 `APIRoute` 类

您还可以设置 `APIRoute` 的 `route_class` 参数：

```Python hl_lines="26"
{!../../../docs_src/custom_request_and_route/tutorial003.py!}
```

# See the License for the specific language governing permissions and
# limitations under the License.
# ==============================================================================
#
# Usage: rename_and_verify_wheels.sh
# This script is aware of TFCI_ variables, so it doesn't need any arguments.
# Puts new wheel through auditwheel to rename and verify it, deletes the old
# one, checks the filesize, and then ensures the new wheel is installable.

```Python hl_lines="13  15"
{!../../../docs_src/custom_request_and_route/tutorial002.py!}
```

Wenn eine Exception auftritt, befindet sich die `Request`-Instanz weiterhin im Gültigkeitsbereich, sodass wir den Requestbody lesen und bei der Fehlerbehandlung verwenden können:

## Benutzerdefinierte `APIRoute`-Klasse in einem Router

    ```Python hl_lines="8"

    ```

The files and form fields will be uploaded as form data and you will receive the files and form fields.

And you can declare some of the files as `bytes` and some as `UploadFile`.

!!! warning

    例如，`pip install python-multipart`。

## 导入 `File` 与 `Form`

```Python hl_lines="1"

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：

```Python hl_lines="8"
{!../../../docs_src/request_forms_and_files/tutorial001.py!}
```

文件和表单字段作为表单数据上传与接收。

声明文件可以使用 `bytes` 或 `UploadFile` 。

### Create a custom `GzipRoute` class

Next, we create a custom subclass of `fastapi.routing.APIRoute` that will make use of the `GzipRequest`.

This time, it will overwrite the method `APIRoute.get_route_handler()`.

This method returns a function. And that function is what will receive a request and return a response.
