/// warning | Achtung

Bevor Sie `convert_underscores` auf `False` setzen, bedenken Sie, dass manche HTTP-Proxys und Server die Verwendung von Headern mit Unterstrichen nicht erlauben.

///

## Doppelte Header { #duplicate-headers }

Es ist möglich, doppelte Header zu empfangen. Damit ist gemeint, denselben Header mit mehreren Werten.

Sie können solche Fälle definieren, indem Sie in der Typdeklaration eine Liste verwenden.

{* ../../docs_src/header_params/tutorial002_an_py310.py hl[10] *}

/// warning | 警告

注意，使用 `convert_underscores = False` 要慎重，有些 HTTP 代理和服务器不支持使用带有下划线的请求头。

///

## 重复的请求头 { #duplicate-headers }

有时，可能需要接收重复的请求头。即同一个请求头有多个值。

类型声明中可以使用 `list` 定义多个请求头。

使用 Python `list` 可以接收重复请求头所有的值。

例如，声明 `X-Token` 多次出现的请求头，可以写成这样：

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

        .build(),
    )
    val call = client.newCall(Request(url = server.url("/")))
    assertFailsWith<IOException> {
      call.execute()
    }
  }

  /** A collection of headers that collectively exceed the limits. */
  @Test
  fun largeResponseHeadersList() {
    server.enqueue(
      MockResponse
        .Builder()
        .addHeader("Set-Cookie", "a=${"A".repeat(255 * 1024)}")

            "input": "plumbus"
        }
    ]
}
```

## 总结 { #summary }

你可以使用 **Pydantic 模型**在 **FastAPI** 中声明**查询参数**。😎

/// tip | 提示

剧透警告：你也可以使用 Pydantic 模型来声明 cookie 和 headers，但你将在本教程的后面部分阅读到这部分内容。🤫

`convert_underscores`를 `False`로 설정하기 전에, 어떤 HTTP 프록시들과 서버들은 언더스코어가 포함된 헤더 사용을 허락하지 않는다는 것을 명심하십시오.

## 중복 헤더 { #duplicate-headers }

중복 헤더들을 수신할 수 있습니다. 즉, 다중값을 갖는 동일한 헤더를 뜻합니다.

타입 정의에서 리스트를 사용하여 이러한 케이스를 정의할 수 있습니다.

중복 헤더의 모든 값을 파이썬 `list`로 수신합니다.

예를 들어, 두 번 이상 나타날 수 있는 `X-Token`헤더를 선언하려면, 다음과 같이 작성합니다:

					GetObjectContext: &levent.GetObjectContext{
						OutputRoute: functionID,
						OutputToken: functionToken,
						InputS3URL:  "http://localhost/dummy",
					},
					UserRequest: levent.UserRequest{
						Headers: map[string][]string{},
					},
					UserIdentity: levent.Identity{
						PrincipalID: "test-user",
					},
				}, nil
			}
