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:

## What is Bit Rot protection?

  - This changes the tokens provided to containers at `/var/run/secrets/kubernetes.io/serviceaccount/token` to be time-limited, auto-refreshed, and invalidated when the containing pod is deleted.
  - Clients should reload the token from disk periodically (once per minute is recommended) to ensure they continue to use a valid token. `k8s.io/client-go` version v11.0.0+ and v0.15.0+ reload tokens automatically.

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。
