# OPA Quickstart Guide [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io)

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

import java.util.Iterator;
import java.util.NoSuchElementException;
import org.jspecify.annotations.Nullable;

/**
 * An iterator that supports a one-element lookahead while iterating.

### Grammar and tone

- Use instructional Turkish, consistent with existing Turkish docs.
- Use imperative/guide language (e.g. "açalım", "gidin", "kopyalayalım", "bir bakalım").
- Avoid filler words and overly long sentences.

 * java.util.function.Supplier} in a context where a {@code com.google.common.base.Supplier} is
 * needed, use {@code supplier::get}.
 *
 * <p>See the Guava User Guide article on <a
 * href="https://github.com/google/guava/wiki/FunctionalExplained">the use of {@code Function}</a>.

# チュートリアル - ユーザーガイド { #tutorial-user-guide }

このチュートリアルでは、**FastAPI**のほとんどの機能を使う方法を段階的に紹介します。

各セクションは前のセクションを踏まえた内容になっています。しかし、トピックごとに分割されているので、特定のAPIのニーズを満たすために、任意の特定のトピックに直接進めるようになっています。

また、将来的にリファレンスとして機能するように構築されているので、後で戻ってきて必要なものを正確に確認できます。

## コードを実行する { #run-the-code }

すべてのコードブロックをコピーして直接使用できます（実際にテストされたPythonファイルです）。

いずれかの例を実行するには、コードを `main.py`ファイルにコピーし、次のように `fastapi dev` を起動します:

<div class="termy">

```console
