**FastAPI**では、これを**OAuth2**を使用して構築できます。

ですが、ちょっとした必要な情報を探すために、長い仕様のすべてを読む必要はありません。

**FastAPI**が提供するツールを使って、セキュリティを制御してみましょう。

## どう見えるか

まずはこのコードを使って、どう動くか観察します。その後で、何が起こっているのか理解しましょう。

## `main.py`を作成

`main.py`に、下記の例をコピーします:

{* ../../docs_src/security/tutorial001.py *}

## 実行

/// info | 情報

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[66:73] hl[71] *}

### Ejecutar la App

Puedes ejecutar la aplicación:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

    }

    @Override
    public int hashCode() {
        return items.hashCode();
    }

     * To check how "1.2.7" compares to "1.2-SNAPSHOT", for example, you can issue

	// assert the status code of the response.
	c.Assert(response.StatusCode, http.StatusOK)

	// constructing http request to delete the bucket.
	// making an attempt to delete an non-empty bucket.
	// expected to fail.
	request, err = newTestSignedRequest(http.MethodDelete, getDeleteBucketURL(s.endPoint, bucketName),
		0, nil, s.accessKey, s.secretKey, s.signer)
	c.Assert(err, nil)

	response, err = s.client.Do(request)
