### 4. Setup MinIO with OPA

Set the `MINIO_POLICY_PLUGIN_URL` as the endpoint that MinIO should send authorization requests to. Then start the server.

```sh
export MINIO_POLICY_PLUGIN_URL=http://localhost:8181/v1/data/httpapi/authz/allow
export MINIO_CI_CD=1
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123

* フロントエンドはそのトークンを一時的にどこかに保存します。
* ユーザーがフロントエンドでクリックして、フロントエンドのWebアプリの別のセクションに移動します。
* フロントエンドはAPIからさらにデータを取得する必要があります。
    * しかし、特定のエンドポイントの認証が必要です。
    * したがって、APIで認証するため、HTTPヘッダー`Authorization`に`Bearer`の文字列とトークンを加えた値を送信します。
    * トークンに`foobar`が含まれている場合、`Authorization`ヘッダーの内容は次のようになります: `Bearer foobar`。

## **FastAPI**の`OAuth2PasswordBearer`

**FastAPI**は、これらのセキュリティ機能を実装するために、抽象度の異なる複数のツールを提供しています。

		version   string
		resource  string
	}{
		{
			version:  "v1",
			resource: "namespaces",
		},
		{
			group:    "rbac.authorization.k8s.io",
			version:  "v1",
			resource: "clusterroles",
		},
		{
			group:    "rbac.authorization.k8s.io",
			version:  "v1",
			resource: "clusterrolebindings",
		},
		{
			group:    "apiextensions.k8s.io",
			version:  "v1",

## Wildcards

It's also possible to declare the list as `"*"` (a "wildcard") to say that all are allowed.

But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware`

The following example shows how to get the details of the user with `{userid}` from `{realm}` realm:

```
curl \
  -H "Authorization: Bearer eyJhbGciOiJSUz..." \
  "http://localhost:8080/auth/admin/realms/{realm}/users/{userid}"
```

### Configure MinIO

                    oauth2.errCb({
                        authId: oauth2.auth.name,
                        source: "auth",
                        level: "warning",
                        message: "Authorization may be unsafe, passed state was changed in server. The passed state wasn't returned from auth server."
                    });
                }

                if (qp.code) {
                    delete oauth2.state;
