不过,也可以使用自定义处理器覆盖默认异常处理器。 ### 覆盖请求验证异常 请求中包含无效数据时,**FastAPI** 内部会触发 `RequestValidationError`。 该异常也内置了默认异常处理器。 覆盖默认异常处理器时需要导入 `RequestValidationError`,并用 `@app.excption_handler(RequestValidationError)` 装饰异常处理器。 这样,异常处理器就可以接收 `Request` 与异常。 {* ../../docs_src/handling_errors/tutorial004.py hl[2,14:16] *} 访问 `/items/foo`,可以看到默认的 JSON 错误信息: ```JSON {Created: Sun Dec 28 07:19:09 GMT 2025 - Last Modified: Sat Oct 11 17:48:49 GMT 2025 - 8.2K bytes - Click Count (0) -

Und es enthält auch einen Default-Exceptionhandler für diesen. Um diesen zu überschreiben, importieren Sie den `RequestValidationError` und verwenden Sie ihn mit `@app.exception_handler(RequestValidationError)`, um den Exceptionhandler zu dekorieren. Der Exceptionhandler erhält einen `Request` und die Exception.

Let's say you have a custom exception `UnicornException` that you (or a library you use) might `raise`. And you want to handle this exception globally with FastAPI. You could add a custom exception handler with `@app.exception_handler()`: {* ../../docs_src/handling_errors/tutorial003_py39.py hl[5:7,13:18,24] *} Here, if you request `/unicorns/yolo`, the *path operation* will `raise` a `UnicornException`.
