OPA is a lightweight general-purpose policy engine that can be co-located with MinIO server, in this document we talk about how to use OPA HTTP API to authorize requests. It can be used with any type of credentials (STS based like OpenID or LDAP, regular IAM users or service accounts).

OPA is enabled through MinIO's Access Management Plugin feature.

## Get started

### 1. Start OPA in a container

```sh
podman run -it \

```Python hl_lines="1"
async def needy_dependency(fresh_value: Annotated[str, Depends(get_value, use_cache=False)]):
    return {"fresh_value": fresh_value}
```

////

//// tab | Python 3.6+ без Annotated

/// tip | Подсказка

Предпочтительнее использовать версию с аннотацией, если это возможно.

///

```Python hl_lines="1"
async def needy_dependency(fresh_value: str = Depends(get_value, use_cache=False)):

    /**
     * Encodes a String as UTF-8 bytes.
     *
     * @param str the String to encode
     * @param dst the destination byte array
     * @param di the starting index in the destination array
     * @param dlim the maximum index in the destination array
     * @return the number of bytes written
     */
    public static int enc_utf8(final String str, final byte[] dst, int di, final int dlim) {
        final int start = di;

## 定義済みの値

*パスパラメータ*を受け取る *path operation* をもち、有効な*パスパラメータ*の値を事前に定義したい場合は、標準のPython <abbr title="Enumeration">`Enum`</abbr> を利用できます。

### `Enum` クラスの作成

`Enum` をインポートし、 `str` と `Enum` を継承したサブクラスを作成します。

`str` を継承することで、APIドキュメントは値が `文字列` でなければいけないことを知り、正確にレンダリングできるようになります。

そして、固定値のクラス属性を作ります。すると、その値が使用可能な値となります:

{* ../../docs_src/path_params/tutorial005.py hl[1,6,7,8,9] *}
