{!../../../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()`。 `APIRoute.get_route_handler()` 方法返回的是函数,并且返回的函数接收请求并返回响应。 本例用它根据原始请求创建 `GzipRequest`。 ```Python hl_lines="18-26" {!../../../docs_src/custom_request_and_route/tutorial001.py!} ``` !!! note "技术细节"

## Accessing the request body in an exception handler !!! tip To solve this same problem, it's probably a lot easier to use the `body` in a custom handler for `RequestValidationError` ([Handling Errors](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

假设要触发的自定义异常叫作 `UnicornException`。 且需要 FastAPI 实现全局处理该异常。 此时,可以用 `@app.exception_handler()` 添加自定义异常控制器: ```Python hl_lines="5-7 13-18 24" {!../../../docs_src/handling_errors/tutorial003.py!} ``` 请求 `/unicorns/yolo` 时,路径操作会触发 `UnicornException`。 但该异常将会被 `unicorn_exception_handler` 处理。 接收到的错误信息清晰明了,HTTP 状态码为 `418`,JSON 内容如下: ```JSON
