Sie könnten einen benutzerdefinierten Exceptionhandler mit `@app.exception_handler()` hinzufügen:

{* ../../docs_src/handling_errors/tutorial003_py39.py hl[5:7,13:18,24] *}

Hier, wenn Sie `/unicorns/yolo` anfordern, wird die *Pfadoperation* eine `UnicornException` `raise`n.

Aber diese wird von `unicorn_exception_handler` gehandhabt.

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：

{* ../../docs_src/handling_errors/tutorial003.py hl[5:7,13:18,24] *}

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
{"message": "Oops! yolo did something. There goes a rainbow..."}

```
