* You can check all the valid Pydantic data types here: <a href="https://docs.pydantic.dev/latest/usage/types/types/" class="external-link" target="_blank">Pydantic data types</a>.

## Example

Here's an example *path operation* with parameters using some of the above types.

		return
	}

	sts, err := credentials.NewSTSClientGrants(stsEndpoint, getTokenExpiry)
	if err != nil {
		log.Fatal(err)
	}

	// Uncomment this to use MinIO API operations by initializing minio
	// client with obtained credentials.

	opts := &minio.Options{
		Creds:        sts,
		BucketLookup: minio.BucketLookupAuto,
	}

	u, err := url.Parse(stsEndpoint)

}
```

These credentials can now be used to perform MinIO API operations, these credentials automatically expire in 1hr. To understand more about credential expiry duration and client grants STS API read further [here](https://github.com/minio/minio/blob/master/docs/sts/client-grants.md).

相対 URL を使うことは、[プロキシと接続](../../advanced/behind-a-proxy.md){.internal-link target=_blank}のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。

///

このパラメーターはエンドポイント/ *path operation*を作成しません。しかし、URL`/token`はクライアントがトークンを取得するために使用するものであると宣言します。この情報は OpenAPI やインタラクティブな API ドキュメントシステムで使われます。

実際のpath operationもすぐに作ります。

/// info | "情報"

非常に厳格な「Pythonista」であれば、パラメーター名のスタイルが`token_url`ではなく`tokenUrl`であることを気に入らないかもしれません。
