### 覆盖 `HTTPException` 错误处理器 { #override-the-httpexception-error-handler }

同理，也可以覆盖 `HTTPException` 的处理器。

例如，只为这些错误返回纯文本响应，而不是 JSON：

                """
                By default, if no HTTP Authorization header is provided, required for
                OAuth2 authentication, it will automatically cancel the request and
                send the client an error.

                If `auto_error` is set to `False`, when the HTTP Authorization header
                is not available, instead of erroring out, the dependency result will
                be `None`.
