一般情况下你可能不会在代码中直接使用它。

但在某些高级场景中需要时，你可以添加自定义响应头：

{* ../../docs_src/handling_errors/tutorial002_py310.py hl[14] *}

## 安装自定义异常处理器 { #install-custom-exception-handlers }

可以使用[与 Starlette 相同的异常处理工具](https://www.starlette.dev/exceptions/)添加自定义异常处理器。

假设有一个自定义异常 `UnicornException`（你自己或你使用的库可能会 `raise` 它）。

并且你希望用 FastAPI 在全局处理该异常。

此时，可以用 `@app.exception_handler()` 添加自定义异常处理器：
