By default this plugin uses HTTP 1.x. To enable HTTP2 use the `MINIO_POLICY_PLUGIN_ENABLE_HTTP2` environment variable.

## Request and Response

MinIO will make a `POST` request with a JSON body to the given plugin URL. If the auth token parameter is set, it will be sent as an authorization header.

The JSON body structure can be seen from this sample:

假设现在包含**FastAPI** app的文件 `main.py`  有些其他**路径操作**。

有个 `GET` 操作会返回错误。

有个 `POST` 操作会返回一些错误。

所有*路径操作* 都需要一个`X-Token` 头。

We see that we are going to need some dependencies used in several places of the application.

So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

또한 코드에서 사용되지 않는 매개변수를 보고 불필요하다고 생각할 수 있는 새로운 개발자의 혼란을 방지하는데 도움이 될 수 있습니다.

이 예시에서 `X-Key`와 `X-Token`이라는 커스텀 헤더를 만들어 사용했습니다.

그러나 실제로 보안을 구현할 때는 통합된 [보안 유틸리티 (다음 챕터)](../security/index.md){.internal-link target=_blank}를 사용하는 것이 더 많은 이점을 얻을 수 있습니다.
