# Response - Изменение cтатус кода

Вы, вероятно, уже читали о том, что можно установить [Состояние ответа по умолчанию](../tutorial/response-status-code.md){.internal-link target=_blank}.

Но в некоторых случаях вам нужно вернуть код состояния, отличный от установленного по умолчанию.

## Пример использования

Например, представьте, что вы хотите возвращать HTTP код состояния "OK" `200` по умолчанию.

	healthNodesOnlineCount  = "nodes_online_count"
)

var (
	healthNodesOfflineCountMD = NewGaugeMD(healthNodesOfflineCount,
		"Count of offline nodes in the cluster")
	healthNodesOnlineCountMD = NewGaugeMD(healthNodesOnlineCount,
		"Count of online nodes in the cluster")
)

// loadClusterHealthNodeMetrics - `MetricsLoaderFn` for cluster health node
// metrics.

    * If you are not switching kube-proxy between different modes, this change should not require any action.

   */
  public final N nodeV() {
    return nodeV;
  }

  /**
   * Returns the node that is adjacent to {@code node} along the origin edge.
   *
   * @throws IllegalArgumentException if this {@link EndpointPair} does not contain {@code node}
   * @since 20.0 (but the argument type was changed from {@code Object} to {@code N} in 31.0)
   */
  public final N adjacentNode(N node) {
    if (node.equals(nodeU)) {
      return nodeV;

  @Test
  public void immutableValueGraphBuilder_addNode() {
    ImmutableValueGraph<String, Integer> graph =
        ValueGraphBuilder.directed().<String, Integer>immutable().addNode("A").build();

    assertThat(graph.nodes()).containsExactly("A");
    assertThat(graph.edges()).isEmpty();
  }

  @Test
  public void immutableValueGraphBuilder_putEdgeFromNodes() {
    ImmutableValueGraph<String, Integer> graph =

public interface SuccessorsFunction<N> {

  /**
   * Returns all nodes in this graph adjacent to {@code node} which can be reached by traversing
   * {@code node}'s outgoing edges in the direction (if any) of the edge.
   *
   * <p>This is <i>not</i> the same as "all nodes reachable from {@code node} by following outgoing
   * edges". For that functionality, see {@link Graphs#reachableNodes(Graph, Object)}.
   *

# 응답 - 상태 코드 변경

기본 [응답 상태 코드 설정](../tutorial/response-status-code.md){.internal-link target=_blank}이 가능하다는 걸 이미 알고 계실 겁니다.

하지만 경우에 따라 기본 설정과 다른 상태 코드를 반환해야 할 때가 있습니다.

## 사용 예

예를 들어 기본적으로 HTTP 상태 코드 "OK" `200`을 반환하고 싶다고 가정해 봅시다.

하지만 데이터가 존재하지 않으면 이를 새로 생성하고, HTTP 상태 코드 "CREATED" `201`을 반환하고자 할 때가 있을 수 있습니다.

이때도 여전히 `response_model`을 사용하여 반환하는 데이터를 필터링하고 변환하고 싶을 수 있습니다.

이런 경우에는 `Response` 파라미터를 사용할 수 있습니다.
