JWT decode(String token)

Decode a token without checking its signature

Implementation

static JWT decode(String token) {
  try {
    final parts = token.split('.');
    var header = jsonBase64.decode(base64Padded(parts[0]));

    dynamic payload;

    try {
      payload = jsonBase64.decode(base64Padded(parts[1]));
    } catch (ex) {
      payload = utf8.decode(base64.decode(base64Padded(parts[1])));
    }

    if (header == null || header is! Map<String, dynamic>) {
      return JWT(payload);
    } else {
      return JWT(
        payload,
        header: header,
      );
    }
  } catch (ex, stackTrace) {
    if (ex is Exception && ex is! JWTException) {
      throw JWTUndefinedException(ex, stackTrace);
    } else {
      rethrow;
    }
  }
