Mais en utilisant `Security` au lieu de `Depends`, **FastAPI** saura qu’il peut déclarer des scopes de sécurité, les utiliser en interne et documenter l’API avec OpenAPI.

Cependant, lorsque vous importez `Query`, `Path`, `Depends`, `Security` et d’autres depuis `fastapi`, ce sont en fait des fonctions qui renvoient des classes spéciales.

## Utiliser `SecurityScopes` { #use-securityscopes }

* Add support in Kubelet to consume container metrics via CRI. [[@yguo0905](https://github.com/yguo0905)]
  * There are known bugs that result in errors when querying Kubelet's stats summary API. We expect to fix them in v1.8.1.

#### kubelet

 *         .catching(DBException.class, e -> "no user", directExecutor())
 *         .finishToFuture();
 * }
 *
 * In this example, when the {@code userName} {@link Future} is done, the transaction and the query
 * result cursor will both be closed, even if the operation is cancelled or fails.
 *
 * <h4>Manually closing</h4>
 *
 * If you want to close the captured objects manually, after you've used the final result, call

		return errCode
	}

	clientETag, err := etag.FromContentMD5(r.Header)
	if err != nil {
		return ErrInvalidDigest
	}

	// Extract either 'X-Amz-Content-Sha256' header or 'X-Amz-Content-Sha256' query parameter (if V4 presigned)
	// Do not verify 'X-Amz-Content-Sha256' if skipSHA256.
	var contentSHA256 []byte
	if skipSHA256 := skipContentSha256Cksum(r); !skipSHA256 && isRequestPresignedSignatureV4(r) {

   * by applying the given {@code AsyncFunction} to the result of the original {@code Future}.
   * Example usage:
   *
   * {@snippet :
   * FluentFuture<RowKey> rowKeyFuture = FluentFuture.from(indexService.lookUp(query));
   * ListenableFuture<QueryResult> queryFuture =
   *     rowKeyFuture.transformAsync(dataService::readFuture, executor);
   * }
   *

		}
	}

	// Parse date header.
	var err error
	date, err = time.Parse(iso8601Format, dateStr)
	if err != nil {
		return cred, "", "", time.Time{}, ErrMalformedDate
	}

	// Query string.
	queryStr := req.Form.Encode()

	// Get canonical request.
	canonicalRequest := getCanonicalRequest(extractedSignedHeaders, payload, queryStr, req.URL.Path, req.Method)

    Previously URLs with special characters like `|` and `[` would break when
    subjected to URI’s overly-strict validation.
 *  Fix: Don't re-encode `+` as `%20` in encoded URL query strings. OkHttp
    prefers `%20` when doing its own encoding, but will retain `+` when that is
    provided.
 *  Fix: Enforce that callers call `WebSocket.close()` on IO errors. Error

`Security` は実際には `Depends` のサブクラスで、後述する追加パラメータが 1 つあるだけです。

しかし `Depends` の代わりに `Security` を使うことで、**FastAPI** はセキュリティスコープを宣言・内部利用でき、OpenAPI で API をドキュメント化できると判断します。

なお、`fastapi` から `Query`、`Path`、`Depends`、`Security` などをインポートする際、それらは実際には特殊なクラスを返す関数です。

///

## `SecurityScopes` を使う { #use-securityscopes }

次に、依存関数 `get_current_user` を更新します。

これは上記の依存関係から使用されます。

	public final fun password ()Ljava/lang/String;
	public final fun pathSegments ()Ljava/util/List;
	public final fun pathSize ()I
	public final fun port ()I
	public final fun query ()Ljava/lang/String;
	public final fun queryParameter (Ljava/lang/String;)Ljava/lang/String;
	public final fun queryParameterName (I)Ljava/lang/String;
	public final fun queryParameterNames ()Ljava/util/Set;

Não! Essa não é a moral da história.
