### 回调路径表达式 { #the-callback-path-expression }

回调*路径*支持包含发送给您的 API 的原始请求的部分的 [OpenAPI 3 表达式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)。

本例中是 `str`：

```Python
"{$callback_url}/invoices/{$request.body.id}"
```

	certificate, err := getTLSCert()
	if err != nil {
		return nil, err
	}
	return &certificate, nil
}

### 콜백 경로 표현식 { #the-callback-path-expression }

콜백 *path*는 *여러분의 API*로 보내진 원래 요청의 일부를 포함할 수 있는 [OpenAPI 3 표현식](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)을 가질 수 있습니다.

이 경우, 다음 `str`입니다:

- Range requests for GetObject/HeadObject for individual files from zip is not supported.
- Names inside ZIP files are kept unmodified, but some may lead to invalid paths. See [Object key naming guidelines](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-keys.html) on safe names.
- This API behavior is limited for following **read** operations on files inside a zip archive:
  - `HeadObject`
  - `GetObject`

In diesem Beispiel verwenden wir zwei erfundene benutzerdefinierte Header `X-Key` und `X-Token`.

Aber in realen Fällen würden Sie bei der Implementierung von Sicherheit mehr Vorteile durch die Verwendung der integrierten [Sicherheits-Werkzeuge (siehe nächstes Kapitel)](../security/index.md) erzielen.
