decodeHeaders static method

Http3Request decodeHeaders(Uint8List bytes)

Decode a QPACK-encoded field section into an Http3Request.

Extracts pseudo-headers (:method, :path, :scheme, :authority) and treats the remainder as regular headers. :authority is stored under the host key. The :scheme pseudo-header is currently ignored.

Implementation

static Http3Request decodeHeaders(Uint8List bytes) {
  final lines = QpackDecoder.decodeFieldLines(bytes);

  String method = '';
  String path = '';
  final headers = <String, String>{};

  for (final line in lines) {
    if (line.name == ':method') {
      method = line.value;
    } else if (line.name == ':path') {
      path = line.value;
    } else if (line.name == ':scheme') {
      // ignored for now
    } else if (line.name == ':authority') {
      headers['host'] = line.value;
    } else {
      headers[line.name] = line.value;
    }
  }

  return Http3Request(method: method, path: path, headers: headers);
}
