你可能之前已经了解到，你可以设置默认的[响应状态码](../tutorial/response-status-code.md)。

但在某些情况下，你需要返回一个不同于默认值的状态码。

## 使用场景 { #use-case }

例如，假设你想默认返回一个HTTP状态码为“OK”`200`。

但如果数据不存在，你想创建它，并返回一个HTTP状态码为“CREATED”`201`。

但你仍然希望能够使用`response_model`过滤和转换你返回的数据。

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数 { #use-a-response-parameter }

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

//     newerThan: "7d" # match objects newer than this value (e.g. 7d10h31s)
//     olderThan: "7d" # match objects older than this value (e.g. 7d10h31s)
//     createdAfter: "date" # match objects created after "date"
//     createdBefore: "date" # match objects created before "date"
//     tags:
//       - key: "name"
//         value: "pick*" # match objects with tag 'name', with all values starting with 'pick'
//     metadata:

    builder.put(k5, v5);
    return builder.build();
  }

  // looking for of() with > 5 entries? Use the builder instead.

  /**
   * Returns a new builder. The generated builder is equivalent to the builder created by the {@link
   * Builder} constructor.
   */
  public static <K, V> Builder<K, V> builder() {
    return new Builder<>();
  }

  /**

    /*
     * We don't "need" to schedule a countDown() call at all here, but by doing
     * so, we come the closest we can to testing that the wait time is
     * appropriately decreased on each progressive await() call.
     */
    TimedLatch latch = new TimedLatch(/* countdownInMillis= */ LONG_DELAY_MS);
    repeatedlyInterruptTestThread(tearDownStack);
    latch.awaitUnsuccessfully(70);

            assertEquals(VALID_UUID_STRING, result.toUpperCase(), "toString() should return the correct UUID string in uppercase");
        }

        @Test
        @DisplayName("toString() should work correctly for UUID created from string")
        void testToStringFromConstructorWithString() {
            // Arrange
            UUID uuid = new UUID(VALID_UUID_STRING);

            // Act
            String result = uuid.toString();

MinIO needs a persistent volume to store configuration and application data. For testing purposes, you can launch MinIO by simply passing a directory (`/data` in the example below). This directory gets created in the container filesystem at the time of container start. But all the data is lost after container exits.

```sh
docker run \
  -p 9000:9000 \
  -p 9001:9001 \
  -e "MINIO_ROOT_USER=AKIAIOSFODNN7EXAMPLE" \

package okhttp3

import javax.net.ssl.SSLSocket
import javax.net.ssl.SSLSocketFactory
import okhttp3.FallbackTestClientSocketFactory.Companion.TLS_FALLBACK_SCSV

/**
 * An SSLSocketFactory that delegates calls. Sockets created by the delegate are wrapped with ones
 * that will not accept the [TLS_FALLBACK_SCSV] cipher, thus bypassing server-side fallback
 * checks on platforms that support it. Unfortunately this wrapping will disable any

## Пример использования { #use-case }

Например, представьте, что вы хотите по умолчанию возвращать HTTP статус-код «OK» `200`.

Но если данные не существовали, вы хотите создать их и вернуть HTTP статус-код «CREATED» `201`.

При этом вы всё ещё хотите иметь возможность фильтровать и преобразовывать возвращаемые данные с помощью `response_model`.

Для таких случаев вы можете использовать параметр `Response`.

	b := make([]byte, size)

	// zeroes
	_, err := NewReader(bytes.NewReader(b), size)
	if err != ErrFormat {
		t.Errorf("zeroes: error=%v, want %v", err, ErrFormat)
	}

	// repeated directoryEndSignatures
	sig := make([]byte, 4)
	binary.LittleEndian.PutUint32(sig, directoryEndSignature)
	for i := 0; i < size-4; i += 4 {
		copy(b[i:i+4], sig)
	}
	_, err = NewReader(bytes.NewReader(b), size)

                    logger.warn("A process was created in $suite but wasn't shutdown properly. Killing PID $pid")
                    KillLeakingJavaProcesses.pkill(pid)
                }
            }
        }
    }
