val parts = header.split(':', limit = 2)
    if (!isSpecialHeader(parts[0])) {
      request.header(parts[0], parts[1])
    }
  }
  referer?.let {
    request.header("Referer", it)
  }
  request.header("User-Agent", userAgent)

  return request.build()
}

private fun Main.mediaType(): MediaType? {
  val mimeType =
    headers?.let {
      for (header in it) {
        val parts = header.split(':', limit = 2)

Таким образом вы можете использовать `user_agent`, как обычно, в коде Python, вместо того, чтобы вводить заглавные буквы как `User_Agent` или что-то подобное.

Если по какой-либо причине вам необходимо отключить автоматическое преобразование подчеркиваний в дефисы, установите для параметра `convert_underscores` в `Header` значение `False`:

=== "Python 3.10+"

	// MinioReleaseURL - release URL.
	MinioReleaseURL = MinioReleaseBaseURL + minioOSARCH + SlashSeparator

	// MinioStoreName - MinIO store name.
	MinioStoreName = "MinIO"

	// MinioUAName - MinIO user agent name.
	MinioUAName = "MinIO"

	// MinioBannerName - MinIO banner name for startup message.
	MinioBannerName = "MinIO Object Storage Server"

	// MinioLicense - MinIO server license.

Aber eine Variable wie `user-agent` ist in Python nicht gültig.

Darum wird `Header` standardmäßig in Parameternamen den Unterstrich (`_`) zu einem Bindestrich (`-`) konvertieren.

HTTP-Header sind außerdem unabhängig von Groß-/Kleinschreibung, darum können Sie sie mittels der Standard-Python-Schreibweise deklarieren (auch bekannt als "snake_case").

      # Unknown hosts will automatically be resolved using upstream dns servers in resolv.conf

    assertThat(recorded.headers["Accept-Encoding"]).isEqualTo("gzip, x-gzip, deflate")
    assertThat(recorded.headers["Connection"]).isEqualTo("keep-alive")
    assertThat(recorded.headers["User-Agent"]!!).startsWith("Apache-HttpClient/")
  }

## 自动转换

`Header` 比 `Path`、`Query` 和 `Cookie` 提供了更多功能。

大部分标准请求头用**连字符**分隔，即**减号**（`-`）。

但是 `user-agent` 这样的变量在 Python 中是无效的。

因此，默认情况下，`Header` 把参数名中的字符由下划线（`_`）改为连字符（`-`）来提取并存档请求头 。

同时，HTTP 的请求头不区分大小写，可以使用 Python 标准样式（即 **snake_case**）进行声明。

因此，可以像在 Python 代码中一样使用 `user_agent` ，无需把首字母大写为 `User_Agent` 等形式。

如需禁用下划线自动转换为连字符，可以把 `Header` 的 `convert_underscores` 参数设置为 `False`：

=== "Python 3.10+"

    assertThat(recorded.headers["Accept"]).isEqualTo("text/plain")
    assertThat(recorded.headers["Accept-Encoding"]).isEqualTo("gzip")
    assertThat(recorded.headers["Connection"]).isNull()
    assertThat(recorded.headers["User-Agent"]!!).matches(Regex("Jetty/.*"))
  }
