  • Method Details

    • headers

      Map<String,List<String>> headers()
      Returns a map of all HTTP headers in this message, sorted in case-insensitive order by their header name.

      This will never be null. If there are no headers an empty map is returned.

      Returns:
      An unmodifiable map of all headers in this message.

    • firstMatchingHeader

      default Optional<String> firstMatchingHeader(String header)
      Perform a case-insensitive search for a particular header in this request, returning the first matching header, if one is found.

      This is useful for headers like 'Content-Type' or 'Content-Length' of which there is expected to be only one value present.

      This is equivalent to invoking SdkHttpUtils.firstMatchingHeader(Map, String)

      .
      Parameters:
      header - The header to search for (case insensitively).
      Returns:
      The first header that matched the requested one, or empty if one was not found.
