getAuthString method

Implementation

String getAuthString(HttpRequestModel res) {
  final cnonce = _computeNonce();
  final url = Uri.parse(res.url);
  final method = res.method.name.toUpperCase();
  final body = res.body ?? '';
  _nc += 1;
  // if url has query parameters, append query to path
  final path = url.hasQuery ? '${url.path}?${url.query}' : url.path;

  // after the first request we have the nonce, so we can provide credentials
  final authValues = computeResponse(
